DOWSIL 991 Silicone High Performance Sealant is specially formulated to prevent staining of porous substrates such as natural stone and minimize streaking on metal panels and glass to improve building aesthetic performance.
It forms a durable, flexible, watertight bond with most building materials and can be used for new and remedial construction applications.
Low VOC emission
Non-staining on natural stone and reduces residue rundown on metal and glass panels.
Low modulus, high movement capability - can accommodate ±50% movement in a properly designed joint.
Good unprimed adhesion to a wide variety of building materials such as natural stone, glass, metal, ceramic tile, fluorocarbon paint finishes and anodized aluminum.
One-part easy to use formulation, good working time.
Formulated to prevent staining of porous substrates and reduce streaking on glass and metal panels to improve building aesthetic performance.
Outstanding UV resistance, excellent weathering and durability resulting in longer lifecycle and superior long-term weatherproofing.
