Description
UltraLok 350 is a two-part methacrylate, structural bonding adhesive designed for the structural bonding of various substrates, including fiberglass, steel, aluminum, and various plastics (not low energy surfaces). Combined at a ratio of 1:1, UL350 has a working time of 25 to 45 minutes and achieves nearly 90 percent of its ultimate strength in 60 to 90 minutes at room temperature curing. UltraLok provides high strength bonds to the above reference surfaces with generally no preparation effort. UltraLok® bonds very strongly to steel, stainless steel, and aluminum metals. UltraLok adhesives are NOT UV STABLE, AND WILL YELLOW OVER TIME and must not be used to create imperceptible seams in countertops or for seaming countertops. This yellowing will not affect bond performance, but will affect bond appearance.
