PLEXUS MA1020
Harmonization Code : 3904.61.00.00 | Polytetrafluoroethylene plates / sheets / film / tape / strip, self-adhesive, in rolls

Main features
- Very Low Cure Shrinkage
- Fast 15-20 Minute Strength Build
- Broad 0.75-9.5 mm Gap Range
Product Description
Plexus MA1020 is a two-part, 10:1 methacrylate adhesive with very low cure shrinkage and very low odor for structural bonding of thermoplastic, metal, and composite assemblies. At 74 deg F (23 deg C), it provides a 5-6 minute work time and reaches approximately 75% of ultimate strength in 15-20 minutes. The non-sagging blue system fills gaps from 0.75 to 9.5 mm. Typical cured properties include 9.0-11.0 MPa tensile strength, 10-20% elongation, and 65 Shore D hardness.
Key features
- Very Low Cure Shrinkage: Provides a very low-shrinkage cure profile.
- 5-6 Minute Working Time: Provides a defined assembly window at 74 deg F (23 deg C).
- 15-20 Minute Strength Build: Reaches approximately 75% of ultimate strength at 74 deg F (23 deg C).
Applications
Applications include structural bonding of thermoplastics, metals, and composites, including plastic and composite assemblies where low odor and low cure shrinkage are important.
