'Vapocure' International Pty. Ltd.[141] developed a low energy, non-polluting process for drying paint, printing inks and coatings which eliminates the need for high temperatures to cure the finish.

A wet film is exposed to a vapour containing a specific catalyst. Typically, the coating is based on a one or two-pack isocyanate polymer, and the catalyst is a volatile amine. The process depends upon the acceleration of the isocyanato (-NCO) and hydroxyl groups to form a urethane or urea bond, or variants of that chemistry, between two polymer molecules; these groups can be attached to other polymers. Contact causes a rapid acceleration of the drying process, and lowers either the energy required, or the time of cure. Since heat is not required the process offers advantages with heat sensitive materials. The technology has been licensed in Australia, USA, Japan and Europe for end uses ranging from metal furniture to plywood, plastic accessories and car refinishing.

Coating for concrete roof tiles

Albright & Wilson[142] (Australia) Pty. Ltd. collaborating with Monier Research & Development Pty. Ltd., produced an acrylate ester copolymer for application to concrete roof tiles immediately after the tiles have been extruded. The coating improves appearance, regulates the curing of the concrete, strengthens the tiles, and prevents efflorescence.
