CrysticROOF® PU Adhesive & Sealant is a one component, polyurethane-based, low modulus sealant. It can be used on its own as an adhesive sealant or a gap sealant for waterproofing your roof. It cures by reaction with atmospheric humidity to produce a joint sealant with a 50% joint movement accommodation factor and excellent adhesion on substrates traditionally problematic for PU sealants, e.g. glass, aluminum, steel, polycarbonate. The extrusion rate and tooling of the sealant remain the same throughout a very wide range of temperature and humidity conditions, as well as being formulated to ensure bubble free cure in these conditions.
• Sealing damaged GRP roofs.
• Sealing joints in insitu concrete, in expansion concrete plates, in precast panels, irrigation channels and in water tanks and swimming pools
• Sealant for metal frames, glass, granite and marble and aluminium windows and panels.
