Stone 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 features excellent fluidity, rapid de-aeration, and superior leveling properties. It exhibits outstanding compatibility with stone powders and aggregates; once cured, the resulting material possesses a dense structure—free of pinholes, cracks, or deformation—and a high surface gloss that, after polishing, closely mimics the texture of natural stone. Furthermore, it demonstrates excellent resistance to abrasion, oil stains, and aging; it resists yellowing and fading over prolonged use, while ensuring strong adhesion and reliable structural integrity.

PLM-983 by POLEMA is a high-performance anti yellowing stone resin specifically formulated for engineered stone, quartz countertops, and marble repair. As an industry-leading stone resin supplier, we deliver this premium resin for stone with low shrinkage and superior hardness to ensure high-gloss, defect-free finishes.

Instructions for Use and Storage Conditions

PLM-983 resin contains no pre-added accelerators; therefore, an appropriate amount of accelerator and curing agent must be added prior to use, based on the specific operating environment and processing requirements.

To ensure that the naturally formed surface of the cured product—specifically the side exposed to air—remains non-tacky, an appropriate amount of paraffin-styrene solution should be added.

To optimize the performance characteristics of the finished product, a post-curing process at 80°C for several hours is recommended.

Prior to use, the resin should be stored indoors in a dry environment at a temperature below 25°C, kept within its original packaging (taking care to avoid opening or damaging the containers).

Elevated temperatures and exposure to light will significantly reduce the product's shelf life; therefore, during storage, the resin must be protected from direct sunlight and kept away from heat sources.

As this styrene-containing unsaturated polyester resin is a flammable liquid, it must be stored away from open flames. Please refer to the Safety Data Sheet (SDS) for further safety information.
