PLEXUS MA205HV
Harmonization Code : 3403.19 | Lubricating Preparations (With 70% or More Petroleum Oils) For Automotive and Other Uses
Main features
- Non-Conductive Electronic Structural Bonding
- 3-5 Minute Work Time
- 15.9 MPa Aluminum Lap Shear
Product Description
Plexus MA205HV is a non-conductive two-part 10:1 methacrylate structural adhesive for electronic assemblies, metals, engineered thermoplastics and composites. At 23.9 deg C, typical work time is 3-5 minutes, and the adhesive reaches 50 psi handling strength in about 7-8 minutes on polycarbonate. The thixotropic system fills gaps from 0.75 to 6.4 mm. After cure, typical tensile strength is 13.7-16.7 MPa, elongation at break is 15-30%, and aluminum lap-shear strength is 15.9 MPa. Primerless metal bonding is supported for manufacturer-listed substrates.
Key features
- Non-conductive structural bonding: The adhesive is positioned for structural electronic assemblies as well as supported metals, thermoplastics and composites.
- 3-5 minute work time: Typical work time is 3-5 minutes at 23.9 deg C, with 50 psi handling strength in about 7-8 minutes on polycarbonate.
- 15.9 MPa aluminum lap shear: Typical aluminum lap-shear strength is 15.9 MPa to ASTM D1002.
Applications
Structural bonding of electronic assemblies; primerless bonding of supported metals; bonding engineered thermoplastics and composites.
