Oxazolidines help PU formulators

摘要

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 trying to develop new technologies include:? retaining and improving performance cure and physical properties of PU systems;? meeting legislative demands such as volatile organic component (VOC) reduction; and ? reducing toxicity by decreasing isocyanate concentration.
