BD403 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 10:1, BD403 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. BD403 provides high strength bonds to the above reference surfaces with generally no preparation effort, yet BD403 has very high elongation and flexibility. BD403 bonds very strongly to steel, stainless steel, and aluminum metals. BD403 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.
