PLEXUS MA310
Description
Plexus MA310
is a two-part methacrylate adhesive designed for structural bonding of thermoplastic, metal, and composite assemblies
1
.
Combined at a 1:1 ratio, it has a working time of 15 to 18 minutes and achieves 75% of ultimate strength in 30 to 35 minutes at room
temperature. MA310 is particularly well suited for bonding thermoplastic materials. This adhesive combines high strength and stiffness with the
ability to bond a wide range of materials. Plexus MA310 is supplied in ready to use cartridges, 20 litre pails or 200 litre drums to be dispensed as
a non-sagging gel.
