CRMCC INDUSTRIAL-GRADE WIDE FORMAT: This heavy-duty Chopped Strand Mat (CSM) comes in a substantial 50-inch width by 30-foot length roll, providing exceptional coverage for large-scale projects. Built tough with a robust 13 ounces per square yard (oz/yd²) weight for superior strength, rigidity, and resin holding capacity.
Premium E-Glass Fiber & Rapid Resin Saturation: Constructed from high-quality E-glass fibers with a reliable soluble binder. Ensures uniform mat distribution and allows for quick, thorough saturation with polyester, vinyl ester, or epoxy resins, creating high-strength, durable laminates efficiently.
Designed for Demanding Large-Scale Applications: The extra-wide 50″ format minimizes seams and significantly speeds up coverage, making it ideal for boat hulls/decks, automotive panels (trucks, RVs), tank and pipe lining, large mold making, industrial repairs, and extensive surface reinforcement.
Easy Handling Meets Structural Integrity: Despite its heavy weight, the chopped strand structure allows for straightforward cutting with heavy-duty shears or a utility knife. Conforms well to compound curves and provides excellent multi-directional strength in the finished laminate.
WARNING: PROPER SAFETY GEAR REQUIRED! Fiberglass fibers can cause severe skin, eye, and respiratory irritation. When handling, cutting, or sanding this heavy-weight mat, ALWAYS wear:  Heavy-duty gloves (e.g., nitrile coated)  Long sleeves and pants (coveralls recommended)  Tight-fitting safety goggles or a full face shield  A NIOSH-approved N95 or P100 respirator/dust mask  Work in a well-ventilated area or use local exhaust ventilation. Avoid generating excessive dust. Wash exposed skin thoroughly after use.
