Abstract
The present disclosure provides a PVC or CPVC solvent cement and a composition for forming a PVC or CPVC coating on an object. The solvent cement and the coating composition each include one or more caprolactam-derived solvents and a polymer selected from the group of polyvinyl chloride and chlorinated polyvinyl chloride. The one or more caprolactam-derived solvents include a linear alkyl group of 1, 2 or 4 unsubstituted carbons or an alkoxymethyl group of 2 or 3 unsubstituted carbons bonded to a nitrogen heteroatom.
Claims9
A solvent cement comprising:
- an N-ethylcaprolactam solvent;
- one or more co-solvents consisting of acetone, methyl ethyl ketone, cyclohexanone, or combinations thereof;
- and
- a polymer selected from the group of polyvinyl chloride and chlorinated polyvinyl chloride, the polymer in solution with the one N-ethylcaprolactam solvent and the one or more co-solvents.
A method of producing a solvent cement, the method comprising:
- providing a polymer selected from the group consisting of polyvinyl chloride and chlorinated polyvinyl chloride;
- providing an N-ethylcaprolactam solvent;
- providing one or more co-solvents consisting of acetone, methyl ethyl ketone, cyclohexanone, or any combinations thereof;
- and
- mixing the polymer, the N-ethylcaprolactam solvent, and the one or more co-solvents until the polymer is in solution with the N-ethylcaprolactam solvent and the one or more co-solvents to produce the solvent cement.
A composition for forming a polymer coating on an object, the composition comprising:
- a polymer selected from the group of polyvinyl chloride and chlorinated polyvinyl chloride;
- an N-ethylcaprolactam solvent;
- and
- one or more co-solvents consisting of acetone, methyl ethyl ketone, cyclohexanone, or any combination thereof, wherein a portion of the polymer is suspended in the composition.
