Abstract
Abstract Highly abrasion-resistant transfer coatings are provided on a wide variety of substrates, thermoplastic or thermosetting, by transfer coating from a mold surface or a flexible web, such as by use of a heat transfer tape, an ultra-thin coating consisting essentially of a non-resinous binder material such as microcrystalline cellulose together with mineral abrasive particles, preferably alumina or a mixture of silica and alumina which have been heated together at a temperature of at least 140°F, the ultra-thin coating also preferably containing a silane and a small quantity of a sticking agent such as a thermoplastic or thermosetting resin.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
76 words
A process for providing an abrasion-resistant deposit on the surface of a substrate, comprising applying to a transfer carrier an ultra-thin deposit consisting essentially of a non-resinous binder material and mineral abrasive particles, drying said ultra-thin deposit at a temperature of at least 140°F, transferring said dried ultra-thin deposit from said carrier to the surface of a substrate under conditions of heat and pressure whereby said deposit becomes adhered to said substrte, and removing said carrier.
Claim 2
Dependent Claim
76 words
A process for providing an abrasion-resistant deposit on the surface of a substrate, comprising applying to a transfer carrier an ultra-thin deposit consisting essentially of a non-resinous binder material and mineral abrasive particles, drying said ultra-thin deposit at a temperature of at least 140°F, transferring said dried ultra-thin deposit from said carrier to the surface of a substrate under conditions of heat and pressure whereby said deposit becomes adhered to said substrte, and removing said carrier.
Claim 3
Dependent Claim
17 words
A process according to Claim 1, wherein said carrier is a mold surface or a flexible web.
Claim 4
Dependent Claim
50 words
A process according to Claim 1 or 2, wherein said binder material consists essentially of microcrystalline cellulose or a mixture of microcrystalline cellulose with a small quantity of carboxy methyl cellulose, optionally a small quantity of a silane and optionally a quantity of finely divided solid lubricant for scuff resistance.
Claim 5
Dependent Claim
33 words
A process according to Claim 1, 2 or 3, wherein said ultra-thin deposit also contains up to about 35% by weight based on the total solids of a sticking agent or film-forming binder.
Claim 6
Dependent Claim
20 words
A process according to Claim 4, wherein said sticking agent or film-forming binder is a thermoplastic or a thermosetting material.
Claim 7
Dependent Claim
26 words
A process according to any one of Claims 1-5, wherein said surface of said substrate is a thermosettable material, a thermoplastic, paper or a wood product.
Claim 8
Dependent Claim
31 words
A product obtained by the process of any one of Claims 1-5, wherein said substrate is a thermoset product other than a decorative laminate, a thermoplastic, paper or a wood product.
Claim 9
Dependent Claim
50 words
A heat transfer for carrying out the process of Claim 1, wherein said transfer carrier is an impermeable, flexible web, said dried ultra-thin deposit being over said web and a plastic layer being over said dried ultra-thin deposit, said plastic layer service as a base coating or an adhesive coating.
Claim 10
Dependent Claim
60 words
A heat transfer according to claim 8, wherein said binder material of said ultra-thin deposit consists essentially of microcrystalline cellulose or a mixture of microcrystalline cellulose with a small quantity of carboxy methyl cellulose, optionally a small quantity of silane, and up to 35% by weight, based on the total weight of solids, of a sticking agent or film-forming binder.
Claim 11
Dependent Claim
75 words
A transfer separator for carrying out the process of Claim 1, wherein said transfer carrier is an impermeable, flexible web, said dried ultra-thin deposit lies over said web, said deposit consisting essentially of microcrystalline cellulose or a mixture of microcrystalline cellulose with a small quantity of carboxy methyl cellulose, and wherein the ultra-thin deposit also contains up to 35% by weight, based on the total weight of solids, of a sticking agent or film-forming binder.
