Sika SikaBiresin® CR72 - Pale Amber - 1 Gallon

Sika SikaBiresin® CR72 Pale Amber 1 Gallon is a premium epoxy lamination system engineered for high-performance marine construction and composite fabrication. This low-viscosity resin delivers exceptional wet-out characteristics across wet layup, vacuum-bagging, and infusion processes, making it the preferred choice for boat builders, marine repair specialists, and composite manufacturers who demand professional-grade results.

The CR72 formula offers versatile curing options through three hardener choices: the SikaBiresin® CH72-1 Fast hardener for expedited production schedules, CH72-2 Medium for balanced working time and cure speed, and CH72-3 Slow for extended pot life during large-scale layups or complex infusion work. This flexibility allows builders to tailor cure rates to ambient conditions and project complexity. The pale amber color provides excellent visibility during application, helping ensure proper resin penetration and composite consolidation. UV resistance is built into the formulation, protecting cured composite structures from sun-induced degradation during storage and use.

Weekend boat owners and serious offshore fishing enthusiasts alike rely on SikaBiresin® CR72 for hull repairs, structural reinforcement, and custom component fabrication. Whether patching a fiberglass hull, bonding stringers and bulkheads, or constructing composite tooling and molds, the CR72 system delivers consistent mechanical properties and reliable adhesion. The 1-gallon size accommodates medium-scale projects while remaining practical for workshop storage. Professionals across the marine industry—from production builders to independent repair shops—choose this resin for its predictable performance, ease of handling, and superior results in demanding saltwater environments.
