4.1 This specification addresses minimum performance criteria for adhesives used to laminate oriented strand board (OSB) structural panel facing material to expanded or extruded polystyrene core materials. Adhesive performance is based on tests that simulate exposure to moisture, temperature, seasonal weathering, and creep. Additionally, the adhesive is to demonstrate resistance to oxidation, mold, chemical reagents, and compatibility to the specific laminating materials.4.2 The adhesive manufacturers can use this specification for new product development and quality control purposes.4.3 Structural insulated panel manufacturers rely on an adhesive performance specification that determines its suitability before use.4.4 Performance of the SIP adhesive when evaluated in accordance with this specification aids in determining the suitability of the adhesive for laminating OSB facings to rigid cellular polystyrene core materials in the manufacture of structural insulated panels.AbstractThis specification addresses the physical, chemical and test requirements for structural insulated panel (SIP) adhesives suitable for the bonding of oriented strand boards (OSB) to rigid cellular polystyrene thermal insulation core materials for general structural use. Douglas-fir to Douglas-fir assemblies shall pass the following qualification requirements when tested in accordance with referenced ASTM documents enumerated herein: block shear strength (dry shear, soak/re-dry, oxidation resistance, and mold resistance); tensile strength (dry tensile bond strength, soak/re-dry, and mold resistance); and creep resistance.
