40668134, Jan 3, 1978

Filed:

Feb 4, 1977

Appl. No.:

5/765472

Inventors:

Donald C. Winters - Whitehouse Station NJ
Laurence F. Haemer - Fairfield NJ
William H. Powell - Livingston NJ

Assignee:

Congoleum Corporation - Kearny NJ

International Classification:

B32B 314
B32B 316

US Classification:

426282

Abstract:

A method of inhibiting or reducing the undesirable growth properties of a resilient flooring product having a fibrous cellulosic backing which comprises: substantially uniformly incorporating in the fibrous cellulosic backing of a resilient flooring product from about 0. 05% by weight to about 4% by weight, based on the weight of the fibrous cellulosic backing, of a growth inhibitor from the group consisting of alums, aluminum sulfate, and mixtures thereof; and installing the resilient flooring product on a surface coated with a water-based adhesive while the fibrous cellulosic backing contains such percentages of the growth inhibitor, whereby undesirable growth, swelling, buckling or the appearance of bubbles in the resilient flooring product is inhibited or reduced, even when the installation takes place at low relative humidity conditions below about 50% relative humidity. The resulting cellulose-backed resilient flooring products having reduced growth properties are also included in the scope of the inventive concept.

Appl. No.:

6/164456

Inventors:

Laurence F. Haemer - Newtown PA

Assignee:

Congoleum Corporation - Kearny NJ

International Classification:

B32B 330
B05D 302

US Classification:

428159

Abstract:

A method of making a differential gloss product which comprises: forming a gelled, potentially foamable, base resinous material; printing thereon a predetermined pattern, some portions containing a urethane polymerization catalyst and either the same or other portions containing a foaming inhibitor; applying to the printed pattern a resinous wear layer; gelling the resinous wear layer and foaming and fusing the resinous materials; applying a urethane coating composition containing no urethane polymerization catalyst to the resinous wear layer; heating to polymerize the portions of the urethane coating composition lying directly over the portions containing the urethane polymerization catalyst to create interspersed high gloss polymerized surfaces; dusting onto the entire surface of the urethane coating composition a powdered particulate or granular material containing a urethane polymerization catalyst; removing the excess particulate or granular materials from the interspersed, polymerized, high gloss areas; and heating to polymerize the remaining surfaces of the urethane coating composition to create thereat low gloss surfaces due to the presence of the occluded particulate or granular materials therein.
