Low Shrinkage Artificial Resin Overview
This product is an unsaturated polyester resin specifically formulated for artificial stone and natural stone applications. It is designed for use in solid surface materials, quartz stone, engineered stone, and marble—including repair work and casting processes—and offers key advantages such as low shrinkage, high gloss, high hardness, ease of polishing, and resistance to yellowing.
The resin exhibits excellent flow properties, rapid de-aeration, and superior self-leveling characteristics. It demonstrates outstanding compatibility with stone powders and aggregates; once cured, the resulting material features a dense structure that is free of pinholes, resistant to cracking, and dimensionally stable. The surface possesses a high degree of gloss, and after polishing, the texture closely resembles that of natural stone. Furthermore, the product offers excellent resistance to abrasion, oil stains, and aging; it resists yellowing and fading over prolonged periods of use, while ensuring strong adhesion and reliable structural integrity.
PLM-770 by POLEMA is an advanced low shrinkage artificial resin specifically engineered for continuous production of large-format quartz and engineered stone slabs. As a leading manufacturer, we deliver this high-strength artificial resin with superior curing stability to ensure your slabs remain flat, crack-free, and highly lustrous after polishing.
Core Performance Advantages
