- Product Uses
- Due to its overall properties, HD-4670 can be used as a finish or a coating.
- This versatile urethane is ideally suited for use as an anti-fray finish on textile fabrics that must have an ultra-soft hand.
- HD-4670 is also ideally suited for textile-coating applications that require excellent low temperature flex crack resistance.
- The extremely low melt temperature also allows HD-4670 to be used as a heat sealable coating.
- Product Applications
- Spray or pad, solids may be adjusted for optimum add-on.
- May be thickened with HA-921 for knife coating.
