Low profile additives (LPA) are compounds added to unsaturated polyester resins or vinyl ester resins to reduce the gel time and exotherm temperature of the resins during curing. LPAs enable resins to form a network structure with low free volume, which leads to lower shrinkage during hardening. They find wide application in applications where dimensional stability is required such as large industrial tooling, fixtures, wind turbine blades, pipes, etc. Rising demand for composites from end- ...
