Abstract
Compositions are provided which employ a fibrous, cellular, absorbent organic material in place of asbestos fiber as a reinforcing and thickening additive; a wide variety of compositions including cements, sealants and paints can be made; a particularly preferred fibrous material is a foamed urea-formaldehyde crushed to a fibrous mass.
Claims15
A composition comprising an organic binder in a liquid vehicle having dispersed therein a thickening and reinforcing amount of fibers of an amorphous, fibrous, cellular, absorbent organic material.
A moldable composition comprising a moldable, solidifiable organic binder in a liquid vehicle having dispersed therein from 1 to 30%, by weight, based on the weight of binder, of an amorphous, cellular, fibrous organic material comprising a disintegrated foam of urea-formaldehyde.
A coated substrate comprising a substrate having a coating thereon comprising a film forming organic binder containing a reinforcing amount of an amorphous, cellular absorbent urea-formaldehyde fibrous material.
A self-supporting sheet comprising a sheet forming organic binder containing a reinforcing amount of an amorphous, cellular, absorbent urea-formaldehyde fibrous material which is characterized by a complex microscopic structure of closed and open cells interspersed with irregular and discontinuous capillaries of 5 to 50 microns in length.
