Wilsor Cotton Fiber

Cotton fibers provide rapid thickening of epoxy and polyester resins. Chopped fibers are ideal for making epoxy adhesives and fillets.

Depending on the desired thickness of the paste, add fiber. For bonding applications, start from 5%, resulting in a thicker, still liquid and well spreadable paste. Adding from 15% or more results in a thick paste similar to putty. The amount of cotton fiber can also be added by feel until the desired consistency is reached; therefore, precise weighing is not necessary. Cotton fiber is an excellent filler for bonding, filling voids and making fillets. The mixture of cotton fiber and resin is highly sandable. Cotton fibers absorb resin, but release it again under pressure, deeply impregnating the wood surface when glued. They are also great for making larger fillets and repairing large holes in wood.
