| National introduces new Bondmaster adhesive National Adhesives has introduced Bondmaster 40-453A, a new adhesive for insulating applications that can bond various facings to lightweight fiberglass for making rolled goods for use in the metal buildings industry. Bondmaster 40-453A is a formulated copolymer emulsion adhesive used for bonding foil/scrim/kraft and other facings to fiberglass insulation in the manufacture of rolled goods for commercial and residential buildings. It has been formulated to offer a high level of wet tack and good mileage. Its high-tack properties reduce the slippage of poly or foil facings when bonded to fiberglass. A 54%-solids adhesive with a viscosity of 800 cps, Bondmaster 40-453A can be roll coated, extruded, or air sprayed. A UL-rating will soon be registered with the product. write your comments about the article :: © 2007 Construction News :: home page |
