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.

An improved film coater which utilizes one or more coater or applicators to transfer coating to the outer surfaces of at least one more rolls, which in turn transfers the coating from the roll surface to one or more sides of the web for coating paper is disclosed. The coater or applicator includes a smoothing doctor on the web and downstream of the one or more rolls, and may also utilize humidity from one of steam showers or a humidity enclosure to assist smoothing. The web may run in any direction, but preferably runs upwardly from the roll toward the doctor to reduce 'film split' droplets effect. The present invention also reduces the fiber rise and arrange peel pattern on the coated web, resulting in a smooth uniform coated paper.
