ADHESION MS57HT is a one-part, high modulus, Silyl-Terminated Polymer elastic adhesive. Once extruded it cures by reaction to the atmospheric moisture to form a high performance, permanently flexible assembly adhesive with high green strenght (high viscosity and high initial tack).
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.
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, because of the high viscosity of the material 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.
For adhesive purposes:
Bonding and fixing: apply adhesive sealant on one side in dots or lines (every 10-30 cm). Always apply adhesive sealant in corners and along edges. Join parts in the right position within 20 minutes and press firmly or tap lightly with a rubber mallet. If necessary, secure or support heavy materials for 24 hours.
Finishing indications and limitations:
ADHESION MS57HT 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.
Since system is moisture-cured, permit sufficient exposure to air.
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 MS57HT can be stored for 12 months in its original packing (unopened container) at 5°-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.

ADHESION MS57HT is a powerful and versatile adhesive sealant for all jobs involving elastic bonding of a wide range of materials including metals, sheet steel (galvanised, plated and painted), untreated or anodised aluminium, brass, copper, glass, GRP, wood, concrete and many rigid plastics.
For use in elastic, structural bonding applications in industrial (assembling of insulated panels; vibration-proof bonding, etc.) automotive, transportation (coach, caravan, refrigerated vehicles, containers) and marine, where a powerful elastic adhesive with High green strength and quick build-up of end strength is required. Long term resistance to fresh water, seawater, limewater, caustic solutions and cleaning agents. Short term resistance to Petrol, grease and mineral oil. Not resistant to organic acids, concentrated mineral acids or solvents. This information is offered for general guidance only. Advice on specific applications will be given on request.
