Aerostrip gives excellent paint stripping performance on conventional aircraft paint schemes and on some age hardened schemes it will even out perform conventional products. Persistent performance over time with one application of product makes Aerostrip very cost-effective to use.

Aerostrip is more environmentally acceptable than conventional dichloromethane based materials. This product is free from chlorinated hydrocarbons, phenolic materials and has no unusual toxicity/health problems.

APPLICATION

Before application

1. Aerostrip should be applied using a 10:1 ratio air driven pump. All pump components that come into contact with Aerostrip should be made of stainless steel or PTFE. Contact Dasic for advice on suitable equipment. Apply the product directly from the drum or via a clean container that does not contain any other paint remover residues or contaminants such as rust.

2. Ensure that the pump is scrupulously clean and that product delivery lines are empty and clean with no paint remover trapped in the connectors.

3. The hangar temperature should be between 23°C and 30°C for best results.

4. All magnesium, perspex, polycarbonate and composite areas should be effectively masked before application of Aerostrip.

5. Never mix Aerostrip with other paint removers as a violent reaction could result.

During application

1. Ensure that the operator complies with all health and safety precautions, including full face protection and eye protection.

2. Ensure adequate ventilation during the stripping process.

3. After the top coat has lifted, it can be beneficial to remove it and apply another layer of Aerostrip.

After application

1. Remove remaining paint residues with a stiff bristle brush or squeegee. Do not confine the denatured paint in closed containers. (Any residual hydrogen peroxide could release oxygen and heat and could cause a dangerous pressure build up.)

2. Clean the treated surfaces with a 10% solution of Dasic Aerokleen DP4477 and then rinse thoroughly with high pressure water.

3. All waste and waste water should be disposed of in accordance with local and national regulations.

4. Thoroughly clean all pumps, product lines and containers with water immediately after application of Aerostrip. Do not use solvents for this purpose as dangerous reactions could occur.

High performance, phenolic, epoxy and polyurethane paint removers

• Extremely effective on chemical resistant epoxy and polyurethane paint schemes
• Suitable for use on all conventional metal and alloys used in aircraft construction
• Superior evaporation retardants increase drying time, therefore, prolonging stripping activity
• Ease of rinsing in order to leave a wax free substrate ready for paint

Dasic D23V has been formulated to give the highest possible efficiency in the removal of the chemical resistant epoxy and polyurethane paint schemes used on aircraft, whilst being suitable for use on all conventional metals and alloys used in aircraft construction.

Dasic D23V can be used for both brush and spray applications.
Increased drying times and, therefore, prolonged stripping activity has been obtained by incorporating highly effective evaporation retardants into the formulation.
Ease of rinsing in order to leave a wax free substrate ready to paint with a minimum of preparation is an additional feature of the products and has been achieved by incorporating superior emulsifying agents into the formulation.

Dasic D23V will degrade the majority of rubber and plastic materials and areas containing these should be masked off before using the products.

APPLICATIONS:

a) Spray/Flow Coating Application
Dasic D23V should be applied using a Dasic D23 Pump Unit. (See separate product data sheet). This unit allows the product to be applied to the surface as a thick even coating without atomising the material.

b) Brush Application
Dasic D23V should be applied to the substrate as a thick even coating. This effect can be most easily obtained by stippling the product onto the surface rather than using a conventional brushing action.

With both application methods, the stripper should be allowed to fully penetrate the paint system, with further applications being overcoated in situations where multiple layers of paint absorb the initial coating of stripper. For maximum effectiveness, no attempt should be made to remove the paint until it is evident that complete blistering has taken place.
In some situations it will be found that the top layer of paint rapidly blisters and separates from the substrate thus reducing the effectiveness of the stripper on the subsequent layers of paint.
Where this occurs, it is advantageous to scrape off the loose paint and re-apply paint remover prior to rinsing. The dwell time will depend on the substrate and the chemical resistance of the paint, but will probably be of the order of 30-90 minutes for an operationally aged system but may extend to several hours where manufacturers' finishes on anodised substrates are encountered.
After complete blistering remaining paint residues may be removed with a Tufnol or Teflon scraper. The area should then be treated with a 2-5% aqueous solution of Dasic Aerokleen CD1 followed by a water rinse. This will leave a totally wax free substrate ready for subsequent pre-treatment and repainting.

NOTE:
Extreme caution should be exercised when opening all paint stripping containers, this includes the wearing of protective clothing and face visor.

Acid activated phenolic paint remover

Dasic D223 is an approved acid activated phenolic paint remover developed to strip the most chemically resistant products of modern paint technology.

Dasic D223 is designed to facilitate the removal of acid cured epoxy coating systems from aluminium substrates and is recommended for use in removing obdurate areas of primer left after stripping with Dasic D23.

IMPORTANT:

Dasic D223 can have a detrimental effect on high tensile steel, magnesium, cadmium plate and zinc substrates and contact with these metals must be avoided. The product will also degrade the majority of rubber and plastic materials. Where adequate masking-off of these materials cannot be guaranteed, Dasic D223 should not be used.

APPLICATIONS:

a) Removal of obdurate primers
Following initial paint removal applications with Dasic D23, the aircraft skin should be rinsed with water and allowed to dry. All susceptible areas must then be efficiently masked off. Dasic D223 should then be applied to the skin surface to give a heavy uniform coat by spray or brush application. Sufficient time should then be allowed for the remover to penetrate the primer coating. Dwell times required will vary according to chemical resistance of the primer but should NOT exceed a period of 2 hours. When the primer coating is sufficiently softened, it should be removed with a Tufnol or Teflon scraper and the area thoroughly washed with a 2-5% aqueous solution of Dasic Aerokleen CD1 followed by a water rinse. This will ensure a wax free substrate ready for subsequent pre-treatment and re-painting.

b) Removal of complete paint schemes
Dasic D223 may be used to strip complete air frames, assuming the correct masking procedures (see above) have been followed. However, in most cases, its use will be limited to specific areas of exceptionally resistant paint that have proved difficult to remove with Dasic D23.

NOTE: Extreme caution should be exercised when opening all paint stripping containers, this

Non-phenolic paint remover

Dasic D83 a thixotropic material which has been specifically developed to provide the aircraft industry with an effective heavy duty application paint remover suitable for use on selectively strippable acrylic and other schemes with low chemical resistances.

Dasic D83 is completely free of both ammonia and phenolic materials.
The formulation incorporates a very effective evaporation retardant and emulsifier system. The former is to minimise solvent loss, thereby preventing the premature \\\\\\\"drying-out\\\\\\\" of the Dasic D83 coating where prolonged dwell times are necessary. The latter factor provides excellent water rinsing properties, leaving a wax free substrate requiring minimal preparation before repainting Dasic D83 will degrade the majority of rubber and plastic materials and areas containing these should be masked off before using paint remover.

APPLICATIONS

a) Spray flow coating application

Dasic D83 is applied by means of the Dasic D23 Pump Unit (see separate product data sheet). This unit allows the product to be applied to the surface as a thick uniform coat which should be allowed to penetrate the paint scheme. The dwell time will depend on the substrate and the chemical resistance and thickness of the paint, but will probably be in the order of 1 - 2 hours. After complete blistering of the area, the paint is removed with a Tufnol or Teflon scraper and the area thoroughly washed with water, or 2-5% aqueous solution of Dasic Aerokleen CD1 followed by a water rinse. This will leave a totally wax free substrate ready for subsequent pre-treatment and repainting.

b) Brush application
Dasic D83 should be stippled on to the substrate to give a thick even coating and then treated as above.

NOTE:

Extreme caution should be exercised when opening all paint stripping containers, this includes the wearing of protective clothing and face visor.

Acid-activated, non-phenolic application paint remover

Dasic D283 is a phenol free, acid activated paint remover, specifically developed to provide the optimum in paint removing power. In situations where legislation inhibits the use of phenolic materials, removal of polyurethane and epoxy paint systems applied to chemically pre-treated aluminium surfaces is now readily achievable. Incorporated within the Dasic D283 formulation is an emulsifier system which ensures effective water rinsing, leaving a wax free substrate which requires minimum preparation before painting.

APPLICATIONS

IMPORTANT:

All susceptible high tensile steel, magnesium and zinc areas should be effectively masked off as Dasic D283 may have a detrimental effect on these materials. Dasic D283 will degrade the majority of rubber and plastic materials and areas containing these should also be masked off before using paint remover.

Dasic D283 should be applied by either brush or by means of the Dasic D23 Pump Unit to give a thick uniform coat which is then allowed to penetrate the paint scheme. The dwell time will depend on the substrate, the chemical resistance and thickness of the paint, but will probably be in the order of 15-60 minutes. A maximum dwell time of 2 hours before removal is recommended.
After complete blistering of the area, paint is removed with Tufnol or Teflon scrapers and the area thoroughly washed with water or a 2-5% aqueous solution of Dasic Aerokleen CD1 followed by a water rinse. This will leave a wax free substrate ready for subsequent pre-treatment and re-painting.

NOTE:

Extreme caution should be exercised when opening all paint stripping containers, this includes the wearing of protective clothing and face visor.
