Product Overview: This product is a specialized low-shrinkage additive designed specifically for compression molding (SMC/BMC) applications. It is formulated to address the issue of curing shrinkage in unsaturated polyester resins, significantly reducing shrinkage rates during the molding process. It effectively resolves common industry pain points such as product warping, surface sink marks, and significant dimensional deviations.
The product exhibits excellent compatibility with various compression molding resins, glass fibers, and fillers, without compromising the system's curing speed or reactivity. Post-molding, the resulting parts feature flat, smooth surfaces—free of ripples or pinholes—along with high dimensional accuracy and excellent consistency. Furthermore, it enhances surface gloss and paint adhesion. This additive is widely applicable to composite products requiring high aesthetic standards and precision, including automotive components, electrical enclosures, sanitary ware, and precision structural parts.
