Plexus® MA300 from ITW is a two-part methacrylate adhesive commonly used for structural bonding of thermoplastics, metals, composites and similar materials. Known for its balanced combination of stiffness, toughness and high strength, MA300 offers a fast cure time and is easy to use with a 1:1 mix ratio. It provides a working time of approximately 3 to 6 minutes and rapidly builds strength at room temperature. Its thixotropic, non-sag formulation makes it suitable for vertical applications, adding to its versatility across a wide range of industries.
Why do people search for alternatives of Plexus® MA300?

Price: Depending on your supplier, Plexus® MA300 can be quite expensive. While you may come across cheaper listings on platforms like Alibaba, these are often expired or grey-market stock sold without warranty or support.
