1st Silicone AS-628, a one component, high performance industrial grade acetic cure silicone sealant. It offers excellent adhesion, UV resistance and elasticity. AS-628 does not crack or discolor when exposed to harsh elements. It adheres to most materials when used with an appropriate primer to form a durable, flexible, waterproof seal on wet area building materials.
Uses of AS-628 include general glazing of glass, fibreglass, plastics, stainless steel & aluminum, waterproofing of wet area building materials, sealing of small glass tanks and shower screens.
