Areas of Application

Sikaflex®-295 UV has been specially developed for the marine industry, where it is used to bond and seal plastic glazing materials in boats and ships. Because of its excellent weatherability this product can also be used to seal joints in exposed areas. Suitable substrates are aluminium (bright or anodized), GRP (polyester resin), stainless steel, timber, 2-component coatings and plastic glazing materials (PC, PMMA). Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex®-295 UV on materials prone to stress cracking. This product is suitable for experienced professional users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.
