CR72 delivers reliable wet-out and bonding across a wide range of fabrics, enabling strong, lightweight laminates for boats, tooling, and parts. The UV-stable pale amber resin preserves clarity in sun exposure, while the non-styrene formulation reduces odor on the job. With three hardeners to tailor cure speed and compatibility with wet layup, vacuum bagging, and infusion, CR72 helps optimize resin distribution and cure quality for above- or below-waterline applications.
