Patent ID: 8871830

Claim:
A pourable glue formulation, comprising: (a) a first aliphatic urethane polymer, wherein the first urethane polymer has a viscosity of about 200 cps, a modulus of about 6,000 psi, and a tensile strength of about 7,800; and wherein the first aliphatic urethane polymer is operative to form a hard, flexible, clear, high gloss film upon drying; offer stain, chemical and water resistance; and provide elongation at high tensile strength; (b) a second aliphatic urethane polymer, wherein the second urethane polymer has a viscosity of about 75 cps, a modulus of about 1,999 psi, and a tensile strength of about 5,150; and wherein the second aliphatic urethane polymer is operative to provide abrasion resistance; high gloss and shear stability, and exhibit adhesion to a wide variety of substrates including nylon and polyester; (c) a freeze-thaw stabilizer, wherein the a freeze-thaw stabilizer is propylene glycol having the formula C 3 H 8 O 2 ; (d) a film-forming compound, wherein the film-forming compound is an ester alcohol having the formula C 12 H 24 O 3 ; (e) a biocide, wherein the biocide is an aqueous blend of chlorinated and non-chlorinated isothiazolinones and 2-bromo-2-nitro-1,3-propanediol; (f) a crosslinking agent, wherein the crosslinking agent is β-(3,4-epoxycyclohexyl)ethyltriethoxysilane; (g) a viscosity modifier, wherein the viscosity modifier is a hydrophobically modified polyethylene oxide urethane; and (h) a defoamer, wherein the defoamer is an organo-modified, silicone-based defoamer.
