Claim 9
Independent Claim
172 words
A method of adhering flexible construction flooring material normally exhibiting a tendency to shrink or curl on aging to a vapor-impermeable flooring surface comprising the steps of: applying to said surface a thin film on a basis of about 200-300 square feet per gallon of a liquid oil-in-water emulsion adhesive composition comprising in parts by weight; an oil phase including: a diene elastomer selected from the group consisting of natural rubber, homopolymers of butadiene, homopolymers of isoprene, polychloroprene, butadiene-isobutylene copolymers, butadiene-acrylonitrile copolymers and butadiene-styrene copolymers- 10-25 rosin ester tackifying resin-10-30 drying oil plasticizer-5-20 C12 to C18 fatty acid-0.5-3.0 volatile solvent having a boiling point from 100*-250* F.-5-10 and a water phase including: water-30-50 a volatile, monovalent amine selected from the group consisting of ammonia, alkylamines, monoethanolamine and triethanolamine-1-5 colloidal thickener comprising hydrophilic aqueous dispersible polymers having a molecular weight above 1,000-0-5 evaporating volatiles from said composition to form a pressure-sensitive residue film; applying the flexible construction material to said residue; and air drying said residue to a cured, rigid, hard, tenacious film.
Claim 10
Dependent Claim
15 words
A method according to claim 10 in which the flexible construction material is vinyl tile.
Claim 11
Dependent Claim
36 words
A method according to claim 10 in which the elastomer is a butadiene-styrene copolymer and the air drying tackifying resin comprises a linseed oil plasticized glycerol ester of rosin and a monoethanolamine-fatty acid emulsifier is present.
Claim 12
Dependent Claim
50 words
An adhesively secured flooring installation comprising: a vapor-impermeable flooring substrate; a layer of flexible construction flooring material; and a film of adhesive securing said layer to said substrate, said film comprising a rigid and tenacious air-dried and cured residue of an oil-in-water liquid emulsion adhesive as defined in claim 1.
Claim 13
Dependent Claim
28 words
A flooring installation according to claim 13 in which the flooring substrate comprises an installed flooring which is vapor-impermeable and the flexible material is formed of vinyl tile.
