Proportioning of Two-Component Epoxy Intumescent Coatings for Passive Fire Protection

In today’s protective coating industry, there is a growing demand to proportion and spray 100% solids coatings that are high viscosity and composed of materials that make them compressible during processing. Epoxy intumescent fireproofing is one such material that starts as somewhat compressible in the pail, and becomes more compressible when heated and agitated under air pressure. This can be a problem for a proportioning machine that meters by volume.

The following paper by Graco explains the different portioning technologies that exist and their ability to handle different materials.
