Dow is now offering designers and specifiers the opportunity to realize an aesthetically pleasing “one-color-edge” for insulating glass, which is a key design element in modern glass facades. This color matched edge sealant system is comprised of a DOWSIL™ Primary and Secondary Sealant which, when combined, offers high performance in gas-filled insulating glass for a homogenous appearance and improved aesthetics at the glass edge.

DOWSIL™ 335 Butyl Sealant Special Black is a heat applied polyisobutylene (PIB) which is suitable for use as the primary edge seal and acts as a gas and moisture barrier. DOWSIL™ Secondary Silicone Sealants help maintain the integrity of both air and gas-filled dual and tripleglazed insulating glass units used in residential and commercial projects. Developed for use in glass assembly using both standard and warm-edge plastic or metal spacers, DOWSIL™ 335 Butyl Sealant Special Black is in full compliance with EN 1279 in an insulating glass (IG) system and offers a very low rate of moisture vapour transmission and gas permeability. It is also compatible with neutral DOWSIL™ Façade Silicones including high quality DOWSIL™ 993 Structural Glazing Sealant.

High performance in warmer climates

DOWSIL™ 335 Butyl Sealant Special Black is suitable for use in high performance glazing systems and designed to perform even under elevated temperatures in specific designs or warmer climates. It’s high temperature resistance of up to 95-100°C, reduces the risk of trickles or flows of the butyl within the insulating glass. With good physical adhesion to glass and a variety of warm-edge and standard spacers, DOWSIL™ 335 Butyl Sealant can be easily applied using standard dispensing equipment.
