Structural Acrylic/ Methacrylate
- Excellent bond strength
- Will bond most substrates
- Works in many environments
- Variety of uses
Structural acrylics, or methyl methacrylate adhesives (MMA), have seen a significant increase in use in recent years. With excellent bond strengths and durability in a range of conditions, MMAs are great for use on a wide range of substrates, including composites, ABS, PVC, acrylic and primed metals. Supplied as two-component products in a range of cartridges and mix ratios, MMAs are widely used in the automotive, bus, truck, rail and marine industries.
MMAs have possibly the best structural bond of any other form of adhesive, and are less likely to be subject to a loss of performance through poor mixing of the two components than other two-component adhesives such as epoxy or polyurethane. When mixed, a strong exothermic reaction forms a bond that generally gives excellent resistance to shear, peel and impact stresses and strains on the joint. They work on poorly-mated surfaces, giving good gap-fill properties, as well as on surfaces that can have other general contamination too. In addition to the substrates mentioned above they can also be used on more everyday items such as glass, wood, concrete and plastic, including bonding a number of dissimilar surfaces.
