Infinity Bond MMA 550 White Methacrylate Adhesive Overview
Infinity Bond MMA 550 White is a two-part, white pigmented methacrylate adhesive designed for structural bonding in marine and industrial applications. With a 10:1 mix ratio and a working time of 40 to 60 minutes, it delivers strong, flexible bonds to fiberglass, aluminum, steel, and various plastics—typically without surface prep. It cures at room temperature, reaching 90% of its final strength in 100 to 120 minutes, and provides excellent gap-filling up to 0.5 inches.
MMA 550 White contains a UV stabilizer to prevent degradation from sunlight, but its high pigment content makes it unsuitable for applications requiring invisible seams, such as countertop seaming. It excels in structural builds that demand durability, weather resistance, and consistent bonding on both metal and composite substrates.
