3M 7010328018 Fiberglass Resin 14 Oz

Product Description

The 3M 7010328018 is a fiberglass resin supplied in a 14 oz container with a 0.20 oz liquid hardener component. Fiberglass resin is a polyester-based compound used to bond, fill, and reinforce fiberglass surfaces. Once mixed with the included liquid hardener, it cures to a rigid, structural finish suitable for patching damaged fiberglass panels, boats, enclosures, and similar substrates. HVAC and plumbing contractors use it when repairing fiberglass ductwork, tanks, or housings. The 14 oz container size is suitable for moderate repair jobs without the waste associated with larger bulk formats.

This resin is applied in maintenance and repair scenarios where a durable, hardened fiberglass patch is required. Typical applications include repair of fiberglass duct board, water tank seams, equipment housings, and structural fiberglass components. It is used by trade professionals across HVAC, plumbing, and general mechanical contracting disciplines when a bonded, cured fiberglass repair is specified.
