Dow Silicones

Structural glazing, curtain wall joints, concrete pavements, perimeter sealing — this range covers Dow's silicone sealants built for Australian building and civil construction. From the ±50% movement capacity of Dowsil 795 and 791 on glass and aluminium façades, to the self-leveling pavement-grade 890-SL and 888 handling +100%/-50% joint movement on concrete, each product is selected for unprimed adhesion, UV stability and low-VOC compliance. One-part, neutral-cure formulations across the range mean predictable performance on concrete, masonry, glass, aluminium, timber and asphalt substrates without primer in most cases.

The right pick depends on your joint type and movement demand. Structural glazing and curtain wall applications call for the higher-modulus options meeting ASTM C 1184, while pavement and expansion joints need the ultra-low modulus self-leveling grades that stay flexible through thermal cycling. All are sausage-format, gun-applied, and built for external exposure.
