Verified by manufacturer 2 months ago
A one part high modulus polyurethane sealant for flooring and expansion joints.
Application
Suitable for use in joints in sea walls, and in trafficked floor joints which require a fast cure.
Description
One part polyurethane sealant which cures, on exposure to moisture vapour, to form a firm, flexible rubber.
Features and benefits:
- Non-biodegradable and abrasion-resistant.
- Not recommended for joints in lightweight cladding, very heavily trafficked areas, or use against natural stone.
- Anticipated service life in excess of 15 years.
- Health and safety: Contains isocyanates; adequate ventilation is required; avoid contact with eyes and skin.
