Product Description
  • Two part, high strength, epoxy adhesive system designed for the structural bonding of metals and plastics. It has proven especially advantageous in such textile equipment applications as metallic wire bonding, and metal comb re-needling.
  • The particular advantages of HAPWELD 661 are its convenient 2:1 mixing ratio (by volume), easy mixing and handling properties, exceptionally high flow and surface wetting qualities, long working life, and uniform cure properties.
  • Very safe handling material with no solvents, fumes, or toxic odors present. Only standard housekeeping practices are required for use.
  • Another major advantage of HAPWELD 661 is it cures completely dry. It is totally free from the blushing or sweating normally associated with many conventional epoxies. This makes HAPWELD 661 ideal for all textile applications by eliminating the possibility of fabric sticking or hang-up and accumulation.
