Increase Strength: Milled fiber glass is a filler material when mixed with resin, body filler, or casting material increases mechanical strength, dimensional stability. Also, help to reduce shrinkage. Thickening Agent: Fiberglass milled when added to resin and mixed thoroughly increases resin thickness, making it applicable to various surfaces. Excellent Reinforcement: Adding a certain quantity of glass fiber powder to resin works as an excellent reinforcement for repairing holes, cracks, and tears under traditional body filler. Compatible: This fiber glass milled is compatible with epoxy, vinyl ester and polyester resin. Wide Applications: Milled glass fiber powder is widely used in the marine industry, automotive industry, construction industry, and repair for electrical, electronics, and automotive components.
