Description
Plexus® MA310 is a two-part, 1:1 mix ratio methacrylate (MMA) adhesive engineered for durable structural bonding of thermoplastics, metals, and composite materials. With a medium open time of 15–18 minutes and a fixture time of 30–40 minutes at 74°F (23°C), MA310 provides an ideal balance of handling flexibility and fast strength development. Its high tensile strength, stiffness, and excellent gap-filling properties make it a go-to adhesive across multiple industries including transportation, marine, signage, and general manufacturing.
