Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
188 words
IN A METHOD OF PRODUCING A RESILIENT SURFACE COVERING HAVING A CONTINUOUS THERMOPLASTIC WEAR LAYER BONDED TO A CARRIER COATED WITH A CONTINUOUS THERMOPLASTIC RESINCONTAINING COATING COMPOSITION, WHEREIN GASES ARE FORMED DURING THE CONSOLIDATING AND FUSING OF THE THERMOPLASTIC RESIN-CONTAINING COMPOSITION WHICH FORMS SAID WEAR LAYER, THE IMPROVEMENT WHICH COMPRISES COATING A CARRIER WITH A PAINT CONTAINING AN ORGANIC FILM FORMER WHICH IS ACTIVATED AT A LOW TEMPERATURE AND AN ORGANIC FILM FORMER WHICH IS ACITVATED AT A RELATIVELY HIGH TEMPERATURE, SUBJECTING SAID COATED CARRIER TO A TEMPERATURE AT WHICH THE SOLVENT IS EVAPORATED AND THE ORGANIC FILM FORMER ACTIVATABLE AT A LOW TEMPERATURE IS ACTIVATED TO FORM A COATED CARRIER HAVING AN AIR PERMEANCE GREATER THAN ABOUT 0.3 CUBIC FOOT PER HOUR PER SQUARE FOOT UNDER A STATIC PRESSURE OF 8" OF WATER AT A TEMPERATURE OF ABOUT 70*F. AND AT A RELATIVE HUMIDITY OF ABOUT 50%, DISPOSIING A THERMOSPLASTIC RESIN-CONTAINING COMPOSITION ON THE COATED SURFACE OF SAID CARRIER, AND CONSOLIDATING AND FUSING SAID THERMOPLASTIC COMPOSITION UNDER HEAT AND PRESSURE TO FORM A WEAR-RESISTANT SURFACE BONDED TO SAID CARRIER AND TO ACTIVATE THE SECOND ORGANIC FILM-FORMING COMPONENT.
