Waxes

In PVC plastisols, waxes provide surface lubrication, reduce friction during processing, and contribute to anti-blocking properties in the final adhesive film.

Fast Flow P is a general-purpose processing wax for hot melt and PVC plastisol systems, while Micron Wax 32 AF is a micronised grade offering superior slip and anti-blocking performance with more precise particle distribution for demanding applications.

When used at appropriate dosage, waxes improve processing without significantly compromising bond strength. Excess wax can migrate to the surface and reduce adhesion, so dosage control is important.

Anti-blocking refers to preventing adhesive surfaces from sticking to each other during storage and handling. Waxes create a thin lubricating layer at the adhesive surface that prevents premature adhesion before intentional bonding.

Wax compatibility depends on the grade and surface treatment. Micronised wax grades like Micron Wax 32 AF can be formulated into both solvent-borne and some water-based systems, though specific compatibility should be verified for each formulation.
