Standard Specification for Adhesive, Casein-Type
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers casein and other protein-based adhesives in the form of dry powder or granular product for use in adhering wood to wood. This specification provides testing procedures and specifies requirements to differentiate the physical, adhesive, and durability properties of commercially available casein and casein-protein adhesives. Adhesives are classified as class B (water resistant) and class C (dry use). Testing procedures include working life, block shear strength, plywood shear test, and storage life. The adhesive shall conform to the viscosity requirement, working life, block shear, tension, and storage life of this specification. Other requirements include instruction sheet, packing, and marking requirements.
Scope
1.1 This specification covers casein and other protein-blend adhesives for use adhering wood to wood. The adhesive type covered by this specification is a dry powder or granular product comprising a mixture of casein, or casein and other protein source, with the necessary dry chemicals to effect solution when the mixture is added to water.
Note 1—Although the term casein adhesive is used throughout this specification, historically, the adhesive subclass described in 1.1 has been known as casein glue. See Terminology D 907, adhesive types.
1.2 Limitations— Cooked casein adhesives are not covered by this specification.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 The following safety hazards caveat pertains only to the test method portion, Sections 8 through 16, of this specification:This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
