Abstract
An antimony-free adhesive package useful for making an insulation facing material includes a halogenated latex adhesive, a flame/smoke suppressant such as aluminum trihydrate, an intumescent such as aluminum polyphosphate, melamine powder, a melamine cyanurate, a mold and mildew inhibitor, an optional dispersant, an optional water holding agent, and optionally between 3% and 10% of a zinc molybdate/magnesium silicate complex and between 3% and 10% of a zinc phosphate/zinc oxide complex. Insulation facing material made with the adhesive package has a 'flame spread' value that does not exceed 25, and a “smoke developed” value that does not exceed 50, and meets the applicable standards for operating temperature, anti-corrosiveness, corrosion, puncture resistance, water vapor transmission, water vapor sorption, shrinkage, microbial growth resistance, and water immersion bond integrity. The facing stock may be used to face insulation products such as rolls, batts, boards or molds of fiberglass or mineral wool insulation.
