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.
