Today’s polyurethane formulators face a number of hurdles when trying to achieve the desired film properties and appearance for their systems. Whether the target is a high gloss finish for a VOC-compliant coating, a fast curing adhesive or a strong, flexible defect-free sealant, the issues facing PU formulators when attempting to develop new technologies include:
- Retaining and improving performance cure and physical properties of PU systems
- Meeting legislation demands such as volatile organic component (VOC) reduction
- Reducing toxicity by decreasing isocyanate concentration
