Sikaflex® primers are specially formulated to be used on specific substrates with Sikaflex® polyurethane sealants. Most substrates require a primer only if testing shows need and where the sealant will be underwater after cure. Some substrates do require a primer under all conditions. Sikaflex® Primer-260 is a dual-purpose clear, almost colourless primer. It is used for promoting adhesion of polyurethane sealants to various metallic, non-metallic and glass substrates.
