Adhesives for Laminating Fire-Rated & Borated Boards

Franklin Adhesives & Polymers' new Laminating 460 is a lamination adhesive developed exclusively to minimize reaction to borates in fire-rated particleboard and fiberboard. The company says this eliminates quick gelling of adhesive upon application to extend working time to five to seven minutes and ensures successful bonding whether cold- or hot-pressed. Used as a one-part product, this crosslinking polyvinyl acetate (PVA) emulsion formulation also offers high water resistance for interior panels and manufacturer can improve the resistance by adding aluminum chloride. As a two-part system, Laminating 460 offers a catalyzed pot life over a 24-hour period, which increases agility during the manufacturing process.
