Product Description

Plexus MA1025 is a two-part 10:1 methacrylate structural adhesive with low cure shrinkage and low odor for thermoplastic, metal and composite assemblies. At 23 deg C, working time is 20-25 minutes and fixture time is 40-45 minutes. The non-sagging adhesive fills bond gaps from 2 to 25 mm and requires little surface preparation for supported substrates. After cure, typical tensile strength is 9.7-12.4 MPa, tensile modulus is 414-552 MPa and strain to failure is 90-110%. Typical lap-shear cohesive strength is 8.3-13.8 MPa to ASTM D1002.

Key features

20-25 minute working time: Working time is 20-25 minutes at 23 deg C, with fixture time in 40-45 minutes.
2-25 mm gap filling: The non-sagging 10:1 adhesive is specified for bond gaps from 2 to 25 mm.
90-110% strain to failure: Typical cured strain to failure is 90-110%, with tensile strength of 9.7-12.4 MPa.

Applications

Structural bonding of thermoplastics, metals and composites; bonding stringers and liners in fiberglass boats; other supported marine structural assemblies.
