Microencapsulatable solvent adhesive composition and method for coupling conduits |
摘要 |
A microencapsulatable solvent adhesive composition for coupling plastic conduits, such as pipes, connectors and related fittings comprises a water-insoluble polymer and a mixture of volatile organic solvents for the polymer, each of the solvents having 6 to 40 carbon atoms. This solvent adhesive composition is suitable for microencapsulation by aqueous-based microencapsulation processes. A plurality of microcapsules encapsulating the solvent adhesive composition are bound to a polymeric surface of a conduit, such as a pipe connector or fitting, by a binder composition, to form a surface coated with a layer of rupturable microcapsules. When the microcapsules are ruptured upon joining of the coated conduit to a second conduit, the volume of the released solvent adhesive composition is sufficient to cement the surfaces together.
