ULTRA-BOND 2187 is a dry-in-place pretreatment for precleaned metal. This zero-phosphorus solution forms a homogeneous organic/inorganic layer on pretreated metals, providing outstanding corrosion protection for pretreated surfaces painted with powder or piqued paints. By depositing a molecular layer onto the surface of precleaned metal, this dry-in-place solution enhances paint adhesion and corrosion resistance. Utilizing a 1-3% concentration for 30-90 seconds, it is more cost-effective than traditional alternatives. Additionally, by eliminating the need for post-coating rinse tanks, ULTRA-BOND 2187 significantly reduces water consumption. It is ideal for use with ferrous, aluminum, zinc and stainless alloys when used as directed.
