Abstract
Using a combination of relatively coarse filler and latex binder, a high solids coating which has a minimum solids content of about 60% by volume, can be produced with a relatively low working viscosity. These very high solids coatings can be applied in thick single layers and oven cured without cracking. They maintain more than 80% of their original wet thickness. The resulting coating provides an extremely hard and durable surface, even on relatively soft mineral fiber board ceiling tiles or wall panels.
