Infinity Bond MMA 230-90 HV High-Viscosity Marine Adhesive

Infinity Bond MMA 230-90 HV Flexible Methacrylate Adhesive for Structural Bonding

Infinity Bond MMA 230-90 HV is a high-viscosity, two-part methacrylate adhesive designed for structural bonding across fiberglass, aluminum, steel, and non-low-energy plastics. With a long 90-minute working time and a flexible cure profile, it’s ideal for bonding dissimilar materials that experience expansion and contraction. This 10:1 mix adhesive cures at room temperature and reaches up to 90% of its ultimate bond strength within 200 to 240 minutes, delivering strong, flexible joints with minimal surface prep.

Its flexibility helps accommodate differences in thermal expansion (CTE) between bonded substrates, making it well-suited for marine and industrial applications. The high-viscosity formula also provides excellent gap-filling performance and vertical hold during setup.
