Sikaflex 260 Primer is a single component primer that enables the sticking of polyurethane sealants on different substrates.
Several surfaces like metal, glass, plastic, etc are not compatible with urethane sealants, hence it becomes problematic to conserve them from water and weather conditions. The Sikaflex 260 Primer facilitates the bonding of these sealants to such complicated surfaces thereby making them waterproof and resistant to weather conditions.The primer comes with a 'ready to use' feature and hence does not require any prior preparation before application. The formula can be effortlessly applied to the surface with the help of a spray, brush, or dauber. There are a bunch of substrates that not only require a primer in underwater conditions but mandate it under all circumstances.
Most substrates require a primer only if testing shows need for it or where the sealant will be underwater after cure. Certain substrates do require a primer under all conditions.
