Also known as Cab-O-Sil, this high-density powder blends cleanly into both 2:1 and 5:1 epoxy resins, allowing you to easily adjust your mixture to a non-sag, putty-like consistency. It is specifically designed for boat builders, woodworkers, and composite repair technicians who need to prevent epoxy runoff on vertical or overhead surfaces. Once fully cured, it forms an extremely hard, high-density solid that drastically increases the overall bond strength of joints. Perfect for structural bonding, heavy-duty gap filling, and creating robust fillets along seams, this industrial-grade additive ensures your repairs withstand high-stress environments and water exposure. It offers an indefinite shelf life when stored properly, making it an essential workshop staple for reliable fiberglass fabrication and wood restoration projects.\n\u003c!-- Rudra Retails-internal-links --\u003e\n\u003cp\u003eShop authentic Mas products — imported from the USA.
