Low Shrinkage Artificial Stone Resin Overview

PLM-770 by POLYMER is an advanced, premium-grade artificial stone resin explicitly engineered for the high-volume production of large-format quartz and engineered stone slabs. As a top-tier unsaturated polyester resin matrix, it serves as the ultimate binder for solid surface materials, artificial marble, and structural stone composites, offering an unmatched balance of extreme dimensional stability, high surface hardness, and brilliant gloss.

Formulated for modern mechanized production, this continuous production quartz resin exhibits exceptional flow properties and rapid vacuum degassing. It penetrates and binds dense stone powders and aggregates flawlessly. Once cured, it creates a void-free, pinhole-free matrix that is highly resistant to impact, household stains, and UV aging. By minimizing curing exotherm, this anti-warping engineered stone resin ensures your jumbo-sized slabs remain perfectly flat, crack-free, and effortlessly polishable to a natural stone-like luster.

Empowering Engineered Stone Manufacturing & Construction

Whether you are operating continuous slab pressing lines or supplying commercial real estate projects, PLM-770 scales with your ambitions:

• For Large Format Quartz Fabricators: The ultimate large format slab polyester resin. Its ultra-low shrinkage rate guarantees zero warping on jumbo slabs (e.g., 3.2m × 1.6m), eliminating costly reject rates and reducing backend calibration time.

• For Kitchen & Bath Contractors: Delivers extreme scratch and stain resistance, providing lifetime durability for high-traffic commercial flooring, architectural wall cladding, and luxury hotel vanity tops.

• For Regional Raw Material Distributors: Sourcing directly from an established artificial stone resin manufacturer in China ensures you receive stable wholesale pricing, bulk IBC/drum packaging, and guaranteed batch-to-batch consistency.

FAQ

Instructions for Use and Storage Conditions

PLM-770 resin contains no pre-added accelerator. An appropriate amount of accelerator and curing agent must be added during use according to your specific pressing line speed and ambient factory environment.

To prevent the natural molding surface in contact with air from remaining sticky after curing, add an appropriate amount of paraffin-styrene solution during mixing.

For optimal mechanical performance, structural hardness, and high-gloss polishing results, a post-curing process at 80℃ for several hours is strongly recommended.

Before use, store the resin tightly sealed in its original package (avoid opening or damaging the drum) in a dry indoor area maintained below 25℃.

Elevated temperature and light exposure will significantly shorten shelf life. Keep away from direct sunlight, windows, and heavy industrial heat sources.

Unsaturated polyester resin containing styrene is a flammable liquid. Keep strictly away from open flames during storage and use. Refer to the SDS for detailed safety protocols.
