Swift®lock 2U210 is a single-component, fully reactive hot melt adhesive with high green strength and medium viscosity. It cross-links through a chemical reaction with moisture in the surrounding air and substrates, producing a thermoset adhesive. This adhesive is specifically formulated for technical laminating applications requiring resistance to highly humid environments and flame resistance.

Suggested Application
  • 2U210 is specifically formulated for technical laminating applications where resistance to highly humid environments and flame resistance are needed.
  • 2U210 exhibits high tack, long open time, excellent specific adhesion and is recommended for simultaneous back coating and foam laminations.
  • It is also recommended for fabric to fabric laminations where 2U210’s medium viscosity and high tack allow for very low coating weights to achieve destructive bonds.
