ADHESION PU55 Body is a one-part, very fast curing, polyurethane elastic adhesive and sealant designed for car body construction and repair which cures on exposure to atmospheric moisture. Specifically developed to meet the car industry requirements, thanks to its balanced viscosity the product can easy to be brushed and tooled in order to match the original brush mark. Once cured, the products reach high levels of hardness that gives a first equipment appearance to the material.
Pre-test substrates for adhesion. Cleaners and/or primers may be required to achieve optimal adhesion. As a rule, the substrates must be prepared in accordance with the NPT instructions; technical guidance regarding adhesion on specific surfaces may be obtained by submitting substrate samples for analysis to our laboratories. Surfaces must be clean, dry, free of water, oil, grease or rust and of sound quality. Remove all loose particles or residues with a jet of compressed air, sandpaper or hard brush. Glass, metal and other non-porous surfaces must be free of any coatings and wiped clean with solvent.
Pierce through the protective membrane in the front threaded section. Screw on the plastic nozzle and cut it at an angle according to the desired bead thickness and profile. Fit the cartridge into a manual or pneumatic air operated gun (provided with telescopic piston) and extrude the adhesive/sealant carefully preventing air entrapment. Once opened, packs should be used up within a relatively short time.
The optimum operating temperature for both substrate and sealant is between 15°C and 25°C.
Long term resistance to fresh water, seawater, lime water and cleaning agents. Short term resistance to petrol, grease and mineral oil. Not resistant to organic acids, concentrated mineral acids, pool water, caustic solutions or solvents. This information is offered for general guidance only. Advice on specific applications will be given on request.
Finishing indications and limitations:
Tooling and finishing must be carried out within the tack-free time of the sealant.
ADHESION PU55 Body can be over-painted. The paint must be tested for compatibility by carrying out preliminary trials. Attention must be observed with the use of alcohol or alkyd-resin since they may interfere with the curing process of the sealant and reduce the drying time of the paint itself. It should be understood that the hardness and film thickness of the paint may impair the elasticity of the sealant and lead to cracking of the paint film.
Avoid exposure to high levels of chlorine (avoid sealing joints in chlorinated swimming pools). Do not cure in the presence of curing silicone sealants. Avoid contact with alcohol and other solvent cleaners during cure. When applying sealant, avoid air-entrapment. Since system is moisture-cured, permit sufficient exposure to air. Bonded elements may require additional holding or support during curing period.
Cleaning of equipment:
Clean tools with acetone or alcohol immediately after use. Cured material can only be removed mechanically.
Personal protective measures:
Keep out of reach of children. If skin contact occurs, remove immediately and wash with soap and water.
ADHESION PU55 Body can be stored for 12 months in its original packaging (unopened container) at 10°- 25°C in a cool, dry place. The storage temperature should not exceed 25°C for extended periods of time. Keep away from wet areas, direct sunlight and heat sources.

Technical certificate suitability of materials and products for use in construction TC 05.13.61.16 from 02.09.2016
ADHESION PU55 Body is suitable for sealing, seam sealing (welded seams, lap panels in all internal vehicle bodywork and painted sheet metals which includes the reproduction of original brush marks and seam sealing), simple bonding as well as for vibration reduction and sound deadening measures in car body repair and car body construction. Suitable substrates are metals, metal primers and paint coatings (2-c systems), painted plastics.
