Sika SikaBiresin® AP112 White Gallon BPO Hardener Required

The Sika SikaBiresin® AP112 White Gallon BPO Hardener Required is a professional-grade epoxy resin system designed for marine repair, restoration, and structural bonding applications where durability and water resistance are essential. This two-part system is ideal for boaters and marine craftspeople who need reliable solutions for reinforcing hull repairs, rebuilding transom sections, or sealing critical joints.

SikaBiresin AP112 is a cycloaliphatic epoxy resin that requires a separate BPO (benzoyl peroxide) hardener to initiate the curing process. This formulation provides excellent adhesion to fiberglass, wood, and metal substrates, ensuring strong and lasting repairs. The white pigmentation is particularly beneficial for above-waterline repairs and cosmetic finishing, where color matching is important.

Once cured, this epoxy exhibits high compressive and flexural strength, making it resistant to fuel, oil, and saltwater intrusion. It maintains its bond even under the stress of engine vibration and hull flexing, making it a preferred choice for professional boat builders, restoration shops, and serious DIY anglers. The gallon-sized container allows for mixing batches of varying sizes, accommodating multi-season projects or fleet maintenance.
