Mastic construction adhesives in fire exposure
U.S. Dept. of Agriculture, Forest Service, Forest Products Laboratory, 1973 - Architecture - 16 pages
Describes two basic methods for testing the heat resistance of mastic construction adhesives. Thirty diversified adhesives were classified as either heat resistant or nonheat resistant. Heat-resistant adhesives in wood-to-wood joints withstood temperatures exceeding 5500 F. and a load of 2 pounds per square inch. Nonheat-resistant adhesives failed at temperatues generally below 3000 F.
