DOWSIL™ 991 Silicone High Performance Sealant

什么 DOWSIL™ 991 Silicone High Performance Sealant?

A low-modulus elastomeric neutral sealant specifically designed to prevent staining of porous substrates such as natural stone and minimize streaking on metal panels and glass.

用途

Specially formulated to prevent staining of porous substrates such as natural stone and minimize streaking on metal panels and glass.
Forms a durable, flexible, watertight bond with most building materials and can be used for new and remedial construction applications.

优势

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
Outstanding UV and weathering resistance
Good working time
10-year Limited Weatherseal and Non-Staining Warranties are available
One-part easy to use formulation
Formulated to prevent staining of porous substrates and reduce streaking on glass and metal panels to improve building aesthetic performance
Excellent weathering and durability resulting in longer lifecycle and superior long-term weatherproofing
