Product Name
- PLEXUS MA1025 Low Cure Shrinkage Two-part Methacrylate Adhesive IT232X /IT235
Brief Description
- PLEXUS MA1025 is a two-part methacrylate adhesive characterized by its very low cure shrinkage and low odor. It is engineered for high-strength structural bonding of diverse materials, including thermoplastics, metals, and composites, often requiring minimal to no surface preparation.
Popular Applications & Uses
- Structural bonding in the marine industry, particularly for stringers and liners in fiberglass boats.- Bonding of automotive components, vehicle roofs, spoilers, and other parts.- Metal assembly and fabrication, including aluminum, stainless steel, and raw steel.- Plastic fabrication, such as ABS, acrylic, PVC, FRP, gelcoats, polyesters, and polycarbonates.- Manufacturing of thermoformed enclosures.- General structural bonding of advanced materials in the transportation sector.- Gap filling applications, capable of filling gaps up to 1 inch (25 mm).
Industries that Commonly Use It
- Aerospace/Defense- Automotive Service/Repair- Construction/ Building Services- Fabrication- General Manufacturing- Marine- Metal Fabrication- Plastic Fabrication- Thermoforming- Transportation/ Specialty Vehicle
Special and Unique Features
- Very low cure shrinkage, which helps maintain dimensional stability after curing.- Very low odor, contributing to improved working conditions.- Requires virtually no surface preparation for many substrates, simplifying the bonding process.- Fast strength development, achieving fixture in 40-45 minutes.- High tensile strength and impressive elongation (90-110%).- Excellent impact, peel, and fatigue resistance, even in vibration-heavy environments.- Tolerant of off-ratio mixing.- Maintains good flexibility at low temperatures.- Resistant to solvents, chemicals, and various environmental conditions.- Incorporates odor blocking technology.- Features low modulus and high elongation for effective stress distribution.
