Chemlok 219 Primer and/or Adhesive
Versatile, single-coat adhesive or primer
Chemlok 219 is a single-component adhesive that can be used as either a one-coat adhesive or as a primer in combination with Chemlok 213 for enhanced environmental resistance. It's formulated with a blend of organic resins and polymers dissolved in an organic solvent system, making it suitable for bonding a wide range of polyether and polyester castable urethanes, as well as certain thermoplastic polyurethanes (TPU) to metal substrates. Its convenient, single-coat application minimizes application time and costs.
