US Classification:

24211832

Abstract:

An improved wood textile bobbin having a single protective wear resistant coating, the coating when applied having the ability to rapidly form a tack free outer surface and cure to a desirable working surface over woods or wood grains that have been previously unusable, wherein the composition for the coating is made up of from about 40 to 65 percent solids consisting of a ricinoleic acid/diphenylmethane diisocyanate prepolymer (MDI) and a moisture activated, blocked, hydroxyl functional acrylic resin, the balance being a solvent in which the solids are dissolved for the purpose of applying the composition to the outer surface of the bobbin substrate.
