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.

A coating composition includes a primary adhesive, a modifier, a smoothing agent, a filler, a secondary adhesive, and a pigment. The primary adhesive is in an amount of about 65.0-85.0 wt % based on the total weight of the coating composition. The modifier is in an amount of about 5.0-15.0 wt % based on the total weight of the coating composition. The smoothing agent is in an amount of about 5.0-15.0 wt % based on the total weight of the coating composition. The filler is in an amount of about 1.0-3.0 wt % based on the total weight of the coating composition. The secondary adhesive is in an amount of about 0.5-10.0 wt % based on the total weight of the coating composition. The pigment is in an amount of about 1.0-10.0 wt % based on the total weight of the coating composition.

The invention relates to a plasticizing composition comprising a vinyl chloride resin and a plasticizing agent which comprises at least one diester having the general formula (I), derived from a diacid selected from succinic acid, glutaric acid, adipic acid, ethylsuccinic acid, methylglutaric acid and mixtures thereof wherein: A is a C.sub.4 to C.sub.6 linear or branched aliphatic chain, and R is an alkyl, a cycloalkyl or an aryl. The plasticizing agent according to the present invention has a good performance for different types of formulations (foam, film and paste). Said plasticizer gels rapidly, has a very low viscosity, and ages very well. Efficient debubblizing is one of the key properties thereof. The foams prepared with said plasticizer have very low densities, a high expansion rate, and excellent qualities.
