Sikaflex-295 UV is an external sealant and a one-component, paste-like polyurethane based adhesive for organic glass windows. On contact with atmospheric moisture, it hardens to form a durable elastomer. Complies with the regulations set out by the International Maritime Organization (IMO). Used in the shipbuilding industry.

Features

• short hardening time
• one-component
• non-continuous
• resistant to weather conditions and the aging process
• approved for the maritime industry (OEM)
• suitable for bonding organic glass

Application

The product has been developed for bonding and sealing organic glass on ships and boats. It is highly resistant to changing weather conditions and can be used to seal external joints. Suitable for bonding surfaces such as aluminum (raw and anodized), GRP (polyester resin), wood, stainless steel, two-component varnishes and organic glass (PC, PMMA).
