3M™ 7000125027 Hardener, 1.48 oz Container Tube Container, Clear, Liquid Form

Dynatron™ liquid hardener works as a catalyst for Dynatron™ polyester fiberglass resin products. Our hardener will enhance the strength and durability of the repair and speed the curing process. Dynatron™ liquid hardener creates a chemical reaction with polyester fiberglass resin for a fast cure and a strong, durable repair. Used as part of a 2-part system, the liquid hardener is mixed with fiberglass resin to create extremely strong, durable and waterproof repairs. Once mixed, the fiberglass resin will cure quickly. Our liquid hardener is a versatile product for use with most repairs involving polyester fiberglass resin. It is an ideal choice for automotive restoration projects. It may also be used for interior and exterior home repairs, including tubs, showers, sinks, pools, hot tubs, boats and more. We packaged this liquid hardener in a tube for easy dispensing. It allows you to control the amount of hardener that you want to add to the fiberglass resin for an optimal ratio.
