Abstract
The present invention relates to primer compositions in non-flowable form. More particularly, the present invention relates to non-flowable primer compositions which are particularly useful for use with curable adhesive and sealant compositions in threadlocking, retaining, bonding and sealing applications and which can be packaged in a convenient pocket-sized applicator dispenser.
Claims14
A primer composition comprising:
- a. at least one primer compound, which can activate polymerization of a polymerizable composition;
- and
- b. a polymeric matrix selected from the group consisting of urea-urethanes, hydroxy or amine-modified aliphatic hydrocarbons, polyester-amide-based rheological additives and combinations thereof, and present in an amount sufficient to render said primer composition non-flowable at temperatures up to about 160° F. (71° C.) and wherein said primer composition is dispensable at room temperature without application of heat.
An article of manufacture comprising:
- a. a dispensing container for housing and dispensing a non-flowable adhesive or sealant composition, said container comprising a generally elongate hollow body having first and second ends, with one of said ends defining a dispense opening;
- b. a primer composition within said container, said composition comprising:
- (i) at least one primer compound;
- and
- (ii) a polymeric matrix selected from the group consisting of urea-urethanes, hydroxy or amine-modified aliphatic hydrocarbons, polyester-amide-based rheological additives and combinations thereof, and present in an amount sufficient to render said primer composition non-flowable at temperatures up to about 160° F. (71° C.) and wherein said primer composition is dispensable at room temperature without application of heat.
