Dow Corning Corp. has released its 1299 Silicone Seam Sealer that outperforms traditional acrylic sealants in narrow seam applications.
Dow Corning said this helps manufacturers deliver windows and doors that prevent air and water infiltration to reduce energy costs. It also delivers proven silicone performance at the cost of lower-performing organics, Dow said.
Other benefits that the company touts include: low odor compared to conventional acrylic alternatives; VOC content compliant to requirements in SCAQMD Rule 1168; self-leveling—flows into narrow joints or over fasteners, eliminating the need for tooling; meets AAMA specification for narrow joint seam sealants; good adhesion to common fenestration assemblies; and silicone performance for long-term durability.
The Dow Corning 1299 Silicone Seam Sealer has a 100 % silicone formulation, the company said, so it will not crack, degrade or discolor. The sealant is not extended with oils or solvents, ensuring there is little to no shrinkage during cure. – Rubbernews.com
