Description of products：ONESIL SN99 is a stand-out, versatile, high-modulus silicone sealant. It is essential in both general building construction and structural glazing bonding tasks. With excellent weather ability, durability, compatibility and impressive tensile strength, it excels in physical, mechanical and adhesive properties.Application：A multi-purpose structural joint sealant for use in buildings of all sizes to provide a protective seal for curtain wall glazing installations. This sealant provides excellent primerless adhesion to a variety of substrates such as coated, enamelled and reflective glass. It also bonds effectively to anodised and polyester-coated or painted aluminium profiles, including most fluoropolymer-based coatings.Application methodApplication method: With manual – orpneumatic caulking gun.Cleaning: Clean with White Spirit or Surface Cleaner immediately after use (before curing).Finishing: With a soapy solution or before skinning.Repair: With the same material.
