Plexus® MA3940LH Two-part Methacrylate Adhesives

Plexus® MA3940LH is a new generation of fast-setting two-part methacrylate adhesives specifically designed for the structural assembly of advanced automotive components. Combined at a 10:1 ratio, it has a working time of 3 to 6 minutes and achieves 75% of ultimate strength in 8 to 10 minutes. After mixing, Plexus MA3940LH cures rapidly to form a tough, elastomeric bond with superb shear, peel, fatigue, and impact strength over a wide temperature range. In addition, this product has superior toughness at temperatures below -17°C. Plexus MA3940LH is off-white and is supplied in ready-to-use cartridge, 5-gallon (20-liter) pails, or 50-gallon (200-liter) drums to be dispensed as a non-sagging gel.
