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 DEG 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: 20
Claim 1
Independent Claim
94 words
A process for providing an abrasion-resistant deposit on the surface of a substrate, comprising providing a transfer carrier coated with an ultra-thin deposit consisting essentially of a non-resinous binder material, a small quantity of finely divided solid lubricant and mineral abrasive particles, which ultra-thin deposit has been dried on said transfer carrier at a temperature of at least 140° F., transferring said dried ultra-thin deposit from said transfer carrier to the surface of a substrate under conditions of heat and pressure whereby said deposit becomes adhered to said substrate, and removing said transfer carrier.
Claim 2
Dependent Claim
94 words
A process for providing an abrasion-resistant deposit on the surface of a substrate, comprising providing a transfer carrier coated with an ultra-thin deposit consisting essentially of a non-resinous binder material, a small quantity of finely divided solid lubricant and mineral abrasive particles, which ultra-thin deposit has been dried on said transfer carrier at a temperature of at least 140° F., transferring said dried ultra-thin deposit from said transfer carrier to the surface of a substrate under conditions of heat and pressure whereby said deposit becomes adhered to said substrate, and removing said transfer 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
29 words
A process according to claim 1, wherein said binder material consists essentially of microcrystalline cellulose or a mixture of microcrystalline cellulose with a small quantity of carboxy methyl cellulose.
Claim 5
Dependent Claim
18 words
A process according to claim 1, wherein said ultra-thin deposit also contains a small quantity of a silane.
Claim 6
Dependent Claim
30 words
A process according to claim 1, 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 7
Dependent Claim
37 words
A process according to claim 3, wherein the ultra-thin deposit also contains a small quantity of a silane and up to about 35% based on the total weight of solids of a sticking agent or film-forming binder.
Claim 8
Dependent Claim
20 words
A process according to claim 6, wherein said sticking agent or film-forming binder is a thermoplastic or a thermosetting material.
Claim 9
Dependent Claim
23 words
A process according to claim 1, wherein said surface of said substrate is a thermosettable material, a thermoplastic, paper or a wood product.
Claim 10
Dependent Claim
28 words
A product obtained by the process of claim 1, wherein said substrate is a thermoset product other than a decorative laminate, a thermoplastic, paper or a wood product.
Claim 11
Dependent Claim
31 words
A product obtained by the process of claim 3, wherein said surface of said substrate is a thermosettable material, other than a decorative laminate a thermoplastic, paper or a wood product.
Claim 12
Dependent Claim
31 words
A product obtained by the process of claim 4, wherein said surface of said substrate is a thermosettable material, other than a decorative laminate a thermoplastic, paper or a wood product.
Claim 13
Dependent Claim
31 words
A product obtained by the process of claim 5, wherein said surface of said substrate is a thermosettable material, other than a decorative laminate a thermoplastic, paper or a wood product.
Claim 14
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 serving as a base coating or an adhesive coating.
Claim 15
Dependent Claim
34 words
A heat transfer according to claim 13, 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.
Claim 16
Dependent Claim
19 words
A heat transfer according to claim 14, wherein the ultra-thin deposit also contains a small quantity of a silane.
Claim 17
Dependent Claim
32 words
A heat transfer according to claim 14, 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.
Claim 18
Dependent Claim
32 words
