Guardian HD-GW Overwrap

Guardian HD-GW Overwrap is a resin pre-impregnated fibreglass repair and reinforcement system designed for pipeline maintenance, corrosion protection, mechanical reinforcement, and emergency pipe repair applications. Activated by water, the polyurethane-impregnated fibreglass tape cures rapidly to form a durable protective outer layer, even in submerged or splash zone environments. The system is suitable for use across pipeline, marine, offshore, industrial, and infrastructure applications where additional mechanical protection or repair reinforcement is required. Guardian HD-GW Overwrap can be used as a standalone repair solution or as a protective overwrap within Guardian Petrolatum and Splash-Zone systems where greater mechanical protection is needed. The system offers high heat resistance, strong dielectric performance, and excellent durability across harsh operating environments while remaining non-toxic, non-combustible, and suitable for underwater application. Key Features Water-activated fibreglass repair system Cures even underwater Suitable for repair, reinforcement, and protection High heat resistance up to 319°C Provides mechanical reinforcement and impact protection Suitable for splash zone and submerged environments Non-toxic, non-combustible, and odourless Can be sanded and painted after curing Commonly Used With Guardian Petrolatum Primer ST Guardian Petrolatum Tape ST Guardian Petrolatum Tape HT Guardian Petrolatum Mastic HT Guardian Petrolatum Mastic UL Guardian Overwrap PVC Tape Applications Emergency pipe repair Pipeline reinforcement Splash zone protection Mechanical protection systems Corrosion protection overwrap Offshore and marine infrastructure Industrial maintenance and rehabilitation Product Datasheet Download the Guardian HD-GW Overwrap datasheet for detailed specifications, sizing, and application guidance.
