What is Chemlok205A?
Chemlok205A is a specialized gray liquid primer developed to enhance the adhesion of Chemlok covercoat adhesives. It effectively bonds both vulcanized and unvulcanized rubber compounds to metals and other rigid materials. This product is a modified version of Chemlok205, containing polymers, organic compounds, and mineral fillers in a primarily ketone-based solvent. In addition to being used as a primer, Chemlok205A serves as a convenient one-coat adhesive for bonding select nitrile rubber compounds.
