MMA-AT425

MMA-AT425

A two-part methacrylate, structural bonding adhesive designed for the structural bonding of various substrates, including fibreglass, steel, aluminium and various plastics (not low energy surfaces). Combined at a ratio of 10:1, AT425 has a working time of 18 – 28 minutes and achieves nearly 90% of its ultimate strength in 50 – 70 minutes at room temperature curing. AT425 provides high strength bonds to the above reference surfaces with generally no preparation effort. AT425 bonds very strongly to steel, stainless steel and aluminium metals. AT425 adhesives are NOT UV STABLE, AND WILL YELLOW OVER TIME and must not be used to create imperceptible seams in counter-tops or for seaming counter-tops. This yellowing will not affect bond performance, but will affect bond appearance.
