CAPA® based coatings are used in varying thicknesses to either form a protective layer or provide the binder for the fibres. In all cases, the flexibility and strength of CAPA® based PU coatings are key factors in their choice. Typical end uses are
- Artificial Leather Production
- Protective Coatings for Leather
- Conveyor Belting
The benefits provided by CAPA® products are
- Very good low temperature flex properties.
- Wide working temperature range.
- Low density polyester system.
- Excellent tear resistance.
- Good adhesion to difficult substrates.
- Very good hydrolysis resistance.
- Light stable aliphatic polyester.
- Very stable prepolymer.
- Consistent controlled reactivity.
- Good oil and UV resistance.
- Low viscosity polyol for ease of processing and reduced solvent requirement.
