## Abstract

A material that is largely an aqueous solution of soluble silicates and a carboxylated resin is described that will form a lubricating adhesive coating on the coke oven doors and jambs which acts to prevent leakage of tar and other coke by-products and the resultant build up as heretofore common in the art and the resultant inability of maintaining a sealing relation between the doors and jambs.

## Claims

### Claim 1

A normally liquid suspension material for forming sealing and lubricating adhesive coatings on coke oven doors and jambs subjected to coke oven operating temperatures and comprising between about 34% to 75% of a solution of water and a soluble silicate wherein the soluble silicate is present at about 40% by weight of the solution, between about 2% to 10% concentrated hydrochloric acid of 90% purity by weight, between about 33% to 75% of a solution of water and a carboxy polymethylene resin wherein the resin is present in amounts between 1% and 10% of the resin solution by weight and withstands said coke oven operating temperatures so that the material will remain in place on the doors and jambs of an operating coke oven.

### Claim 2 (depends on 1)

The liquid suspension material of claim 1 and wherein the soluble silicate is a solution of water and sodium silicate wherein the sodium silicate is present at about 40% of the solution.
