Lamal™ HSA adhesive is the polyether urethane component of a two-component laminating adhesive which requires the use of a coreactant. This polyether urethane, in conjunction with coreactant Lamal C or Lamal CR1-80, functions as an adhesive for flexible packaging. Lamal HSA adhesive is different from most conventional polyurethane adhesives in that it is not affected by alcohols or small amounts of water. Lamal HSA adhesive adheres to a wide variety of substrates including cellophane, treated polyolefins, paper, polyester, polyamides, PVDC-coated and metallized materials, vinyl, and treated heat sealable layers of coextrusions. The optimum performance of the Lamal HSA adhesive is achieved when substrates are corona treated.
Features & Benefits
Lamal™ HSA adhesive provides optical clarity, high bond strength, high heat resistance, and moderate chemical resistance. The admixed Lamal HSA adhesive is unaffected by high humidity and temperature other than by the normal loss of solvent by evaporation.
