BSI Insta-Set Accelerator 6.5 Ounce AerosolINSTA SET is a catalyst which acts as an accelerator that allows CAs to quickly cure in thick layers by enhancing the alkaline conditions during polymerization. INSTA SET is normally used to cure the CA that flows from joints when parts are pressed together. Applying an additional bead of thick CA along a seam and then curing it with INSTA SET significantly enhances a joints strength. For difficult to bond materials, INSTA SET can be applied to one
