RAL 9004
CT1’s TRIBRID® CT1535206 formula has made this sealant 360% stronger with 250% more elongation than traditional hybrid polymers, providing a solid, non-porous cure that doesn’t shrink or crack (In tests carried out under BS EN ISO 8339:2005).
CT1 Black delivers a watertight seal that can be used in a range of applications both inside and outside of the home, even in extreme weather conditions.
CT1 Black provides amazing colour retention, is UV resistant, 100% eco compliant, non-toxic and contains no isocyanates or solvents. Its non-porous characteristics means bacteria and microbes cannot penetrate the cured surface eliminating potentially harmful mould and fungus.
On powder coated aluminium advice should be sought from the manufacturer of the powder coating on the suitability of their product to accept adhesives bonding to the surface layer.
CT1 Black is a unique Tribrid® polymer sealant and construction adhesive with superior strength adhesion on virtually any material in most applications, internal and external, without the need for additional fixings.
CT1 will successfully bond to metals (including lead), glass, mirrors, wood, stone, concrete, polystyrene and most plastics.
For best results, prior testing is recommended on all substrates
