BD404 is a two-part methacrylate, low exotherm, high flexural, structural bonding adhesive designed for the structural bonding of various substrates, including fiberglass, various metals, steel, aluminum, and various plastics (not low energy surfaces). Combined at a ratio of 2:1, BD404 has a working time of 3 to 6 minutes and achieves nearly 90 percent of its ultimate strength in 10 to 15 minutes at room temperature curing. BD404 provides high strength bonds to the above reference surfaces with generally no preparation effort, yet BD404 has very high elongation and flexibility. BD404 bonds very strongly to steel, stainless steel, and aluminum metals. BD404 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.
