Sika SikaBiresin® CH72-2 Medium Cure - Pale Amber - Quart

The Sika SikaBiresin® CH72-2 Medium Cure epoxy resin system in pale amber is a professional-grade marine adhesive and structural coating engineered for serious boat builders, hull repair specialists, and fiberglass restoration work. This product is designed to ensure the integrity of boats by providing adhesives that withstand constant flex, salt exposure, and temperature cycling.

The medium-cure formulation of SikaBiresin® CH72-2 strikes a balance between working time and strength development, allowing for efficient handling and positioning of components. Its pale amber color remains transparent enough to inspect bond lines and structural integrity, while achieving excellent adhesion to fiberglass, wood, foam cores, and composite materials commonly used in boat construction.

Ideal for boatyard projects, repair shops, and custom builders, this one-quart container provides a reliable supply without the need for larger bulk quantities. The gap-filling capability and low exotherm of this epoxy make it suitable for bonding larger surface areas or thick laminations, minimizing the risk of overheating or crazing that could compromise structural strength in marine applications.
