Coating Systems

Coating is the process where by the thermoplastic resin is applied to the substrate material. There are many coating methods in use, some of the more commonly used ones being:

1. Scatter coating – This method uses electronically controlled scattering heads to deposit the resin on to the moving substrate.

2. Dry-dot-printing – In this process, the resin is printed on to the substrate by a roller engraved with small indentations, which hold the resin powder.

3. Performed – The resin is heat processed to form a net which is then laminated on to the base cloth by heat and pressure. During heating, the net melts and leaves a minute dot pattern on the substrate.

A coating system is basically concerned with flexibility and uniformity and these factors have to be considered when evaluating the use of specific fusibles.
