New Dow Corning Adhesives and Sealants Help Meet Appliance Assembly Challenges

The development of new materials has helped increase the performance and efficiency of home appliances. But some of these materials also present unique challenges in assembly and sealing. Dow Corning has introduced new adhesive and sealant products to help meet those challenges. “These materials are engineered to provide appliance manufacturers higher productivity, enhanced design options and cost-in-use savings,” says Gifford Shearer, Industrial Assembly & Maintenance Market Leader at Dow Corning.

Instant Green Strength Adhesive for High Throughput
“Silicone-based sealants offer excellent performance properties for many appliance applications,” says Shearer. “With the introduction of new silicone hot melt sealants, Dow Corning is helping to satisfy appliance manufacturers’ needs for high-speed, high-volume production with an alternative to mechanical fasteners or pressure-sensitive tapes.”

Dow Corning HM-2600Dow Corning HM-2600 Silicone Assembly Sealant offers excellent clarity, tenacious adhesion to many substrates (metals and various plastics including low surface energy types) as well as instant green strength to enable high assembly throughput. The new adhesive is suitable for use with XY tables, robots and other automatic dispensing and assembly methods, Galbraith says. “Compared to organic hot melt adhesives, it offers long open/working time before curing to a flexible yet tough adhesive.”

Dow Corning HM-2600 Silicone Assembly Sealant is certified to UL94 HB and currently is being tested for food contact and drinking water contact.
