Sika Sikaflex 291i sealant is a one-component polyurethane product designed for marine applications. It cures with atmospheric moisture, stays in place without sagging, and can be used for both sealing and bonding. It meets the International Maritime Organization’s criteria for low flame spread.
It has high elasticity, a mild odour and is non-corrosive. It is solvent-free, with particularly low volatile organic compound (VOC) emissions and a low isocyanate content. It can be painted once a skin has formed.
