Abstract
A protective coating of finely divided abrasion resistant resin is diluted with a solvent and applied to a surface. The applied coating is cured to achieve either a single layer of inert dispersed in the resin, or two layers including a dense layer of inert in resin covered by a thin layer of resin, and to provide a glossy or matte appearance as desired.
Claims9
A method for protecting metal surfaces, said method comprising the steps of:
- (a) sand blasting said surfaces to provide a prepared surface having a desired anchor pattern;
- (b) removing substantially all dust particulant material from said prepared surface;
- (c) mixing a corrosion resistant resin containing finely divided abrasion resistant particles with the appropriate hardening catalyst for said resin to form a base composition coating mixture;
- (d) diluting said coating mixture with a selected solvent to allow even application of said coating mixture;
- (e) applying said coating mixture to said prepared surface to obtain a desired thickness;
- and
- (f) curing said coating as applied at room temperature of 72.degree. F. for 8 to 12 hours to obtain a coating on said surface having a first layer of concentrated abrasion resistant particles proximate said surface and a second layer of corrosion resistant resin over said first layer, wherein said corrosion resistant resin comprises 90% by weight finely divided ceramic particles and a 10% by weight bisophynol A epoxy resin including a polyamide elastomer.

A method for protecting metal surfaces, said method comprising the steps of:
- (a) sand blasting said surface to provide a prepared surface having the desired anchor pattern;
- (b) removing substantially all dust and particulant material from said prepared surface;
- (c) mixing a corrosion resistant resin with finely divided abrasion resistant particles with the appropriate hardening catalysts for said resin to form a base composition coating mixture wherein said corrosion resistant resin coating comprises 90% by weight finely divided ceramic particles and a 10% by weight bisophynal A epoxy resin including a polyamide elastomer;
- (d) diluting said coating mixture with a selected solvent to allow even application of said coating mixture;
- (e) applying said coating mixture to said prepared surface to obtain a desired a thickness;
- and,
- (f) sequentially curing said coating as applied first at room temperature (72.degree. F.) for 1/2 to 1 hour and then at 250.degree. F. to 300.degree. F. for 1 to 11/2 hours to obtain a coating on said surface having a first layer of concentrated abrasion resistant particles proximate said surface and a second layer of corrosion resistant resin over said first layer.
