PRODUCT DESCRIPTION

LOCTITE? Product 207 Clear is a single component, neutral ( non-acetic) silicone sealant specially developed for polycarbonate, plastic materials in general, mirrors, non-ferrous metals, concrete and ceramics. This material cures on exposure to moisture in the air to form a tough, flexible, silicone rubber seal. The product resists aging, weathering and thermal cycling without hardening, shrinking or cracking.
