CRMCC Premium Fiberglass Chopped Strand Mat (CSM): Conveniently sized at 4 inches wide by 30 feet long per roll, offering ample coverage for various projects. Engineered with a durable 13 oz/yd² weight for optimal strength and resin absorption.
High-Quality E-Glass Fiber Construction: Made from premium E-glass fibers bonded with a soluble binder. This ensures consistent mat distribution, easy handling, and rapid saturation with polyester, vinyl ester, or epoxy resin for a strong, reliable laminate.
Versatile Reinforcement Solution: Perfect for a wide range of fiberglass repair and fabrication tasks. Ideal for boat hull & deck repairs, automotive bodywork (rust repair, panel replacement), RV maintenance, shower/tub enclosures, custom fiberglass projects, and pool/spa repairs.
Easy to Cut, Shape & Saturate: The chopped strand structure allows for effortless cutting with scissors or a utility knife and conforms easily to curves and complex shapes. Designed for quick and thorough wet-out with compatible resins.
WARNING: Fiberglass fibers can irritate skin, eyes, and respiratory system. Always wear appropriate personal protective equipment (PPE) including gloves, long sleeves, eye protection (safety goggles), and a NIOSH-approved dust mask or respirator when handling and cutting this material. Work in a well-ventilated area.
