CAPA® polymers including thermoplastics and polyols are used in the production of moisture cured reactive hot melts. The unique combination of properties means that reactive hot melts with wide ranges of viscosities and bond strengths can be made. Typical end uses are:
- Bookbinding
- Textile bonding
- Structural adhesives
- Shoes
CAPA® polyols are used to produce the prepolymer component in reactive hot melts. This is due to the very low viscosity that CAPA® polyols have when compared to adipate polyesters. This means that much higher molecular weight CAPA® polyols can be used and higher bond strengths achieved.
CAPA® thermoplastics provide the initial bond strength without a detrimental effect on the ease of application characteristic of the adhesive.
