(Adnkronos) – DANVERS, Mass., April 4, 2022 /PRNewswire/ — The Plexus team at ITW Performance Polymers is introducing Plexus MA8105 as its newest adhesive, continuing to push the limits of what is possible with MMA (methyl methacrylate) adhesives and addressing the challenges of earlier generations.
MMA structural adhesives offer distinct advantages over other adhesives: Fast room temperature curing, excellent mechanical properties, and a broad range of adhesion. Older MMA adhesives bond a wide range of materials but struggle with “difficult to bond” metals like hot dipped galvanized steel, or tough semi-crystalline plastics like polyamides (nylons).
Challenges and Requirements Broad Adhesion – Customers need to bond a full range of materials. Older generations of adhesives had difficulty bonding galvanized steel, nylons to composites, other metals and plastics. High Temperature Resistance – Certain applications require high strength even at 180°F (82°C) or higher. Fast Throughput – The adhesive strength development must match expectations. Making more parts per hour improves efficiency and lowers cost. Toughness Requirement – Users need high strength adhesives with good elongation handling impact and fatigue. Cure Tack-Free, Sandable & Paintable – Adhesive squeeze out happens. It’s beneficial to have an adhesive that cures tack-free and accepts most paints. Non-Sag on Vertical Surfaces – It stays where you put it. Handle Off-Ratio Mixing – Older adhesives require exact mix ratios.
Expanding the Plexus MA8100 Brand Enter MA8105, a 5-minute working time product with fixture times between 12-15 minutes. MA8105 takes the robust adhesion of other MA8100 series products and adds quicker product throughput.
The Results MA8105 has excellent primerless adhesion to a wide range of substrates. Composites, painted metals, and amorphous thermoplastics are often bonded with little to no surface preparation. MA8105 adhesive even bonds oily metals. MA8105 withstands long-term environmental exposure. Parts can be bonded and survive in typical outdoor environments with significantly higher heat resistance than competitive structural adhesives. MA8105 cures quickly in a range of temperatures, enabling fast throughput. Quick dispensing and part joining mean manufacturing and assembly are optimized, producing more parts per hour. Labor shortages mean manufacturers can turn to the creative solutions of adhering their parts in a fast, efficient manner.
