The polychloroprene adhesives covered by this specification are suitable where adherence to polychloroprene coated fabric is required, such as in the manufacture and repair of life vests, decoy targets, and pontoons. Classes 1,2, and 3 adhesives, which are required to meet the dead load test, are heat stable up to 140° F, and should be used in the above applications, They are recommended for use where heat stability to 140° F is required. Since Classes 4 and 5 adhesives are not required to meet the dead load test, and their heat stability up to 140° F cannot be predicted, they should not be used in applications where heat stability to 140° F is required.
