Fuller offers fast cure and slow cure MMA products that provide stress and impact resistance, are color matching, gap filling, paintable, sandable, and have high tensile, shear, and peel strengths. The PVC TrimWelder MMA products are also solvent-free and require no surface preparation when joining plastics, metals, aluminum, or composites. Our PVC TrimWelder™ Fast Cure adhesive has a 4 to 7 minute work time with 80 percent strength in just 30 minutes, while the PVC TrimWelder™ Slow Cure adhesive has a 20 to 25 minute working time with 80 percent strength in 90 to 120 minutes. The fast cure and slow cure systems are also both stronger than the PVC board substrates that they bond.
