MS Krystal Sealant is a premium, one-component, moisture-curing Modified Silane (MS Polymer) adhesive and sealant. It combines the elasticity of silicone with the paintability and bonding strength of polyurethane, while being free from solvents, isocyanates, and silicone.
The cured sealant forms a crystal-clear, flexible, weather-resistant bond suitable for both interior in the and exterior applications.
