Abstract

Abstract A liquid multi-purpose coating composition is disclosed which has significant resistance to heat transfer. The coating composition may be applied to many different types of substrates including wood, metal, concrete and other structural materials. The composition is a water-based liquid containing principally kaolin, staple fibers and a dispersing agent. The coating composition and articles coated therewith exhibit excellent insulating properties against heat and radiant energy. Considerable energy savings and various economies are obtained by the insulative compositions.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 51 words
An insulative aqueous coating composition containing film-forming solids consisting essentially of kaolin particles in an amount on the order of about 30% to about 90% by weight, staple fibers and a dispersing agent for said solids in the aqueous composition, said kaolin particles having a diameter less than about 50 microns.
Claim 2
Dependent Claim 51 words
An insulative aqueous coating composition containing film-forming solids consisting essentially of kaolin particles in an amount on the order of about 30% to about 90% by weight, staple fibers and a dispersing agent for said solids in the aqueous composition, said kaolin particles having a diameter less than about 50 microns.
Claim 3
Dependent Claim 10 words
The composition of claim 1 further comprising a thickening agent.
Claim 4
Dependent Claim 13 words
The composition of claim 2 wherein said thickening agent is a cellulosic thickener.
Claim 5
Dependent Claim 22 words
The composition of claim 3 wherein said cellulosic thickener is selected from the group of methyl cellulose, hydroxyethyl cellulose and carboxymethyl cellulose.
Claim 6
Dependent Claim 14 words
