Unsaturated Polyester Resin for Marble

This Polyester Resin is a high-reactivity, premium polymer system designed to produce solid surface sheets, cultured marble panels, onyx slabs, and engineered stone products. This resin delivers excellent color transparency, controlled gel time, and high filler acceptance, making it ideal for mass-production marble casting lines and marble coating.

Unsaturated Polyester Resin for Marble has strong mechanical performance, polishing ability, and minimal shrinkage, it ensures a glossy, seamless finish similar to natural stone that can be used for producing  artificial marble slabs, onyx bathroom panels, kitchen countertops, decorative wall sheets, vanity tops, shower trays, stair blocks, molded stone basins, and engineered solid-surface construction composites. This resin is widely used in housing projects, interior architectural design, sanitary ware, luxury hotels, and large-volume building material manufacturing. Its Composition typically include orthophthalic or isophthalic UPR base resin, styrene monomer, curing accelerators (Co-Naphthenate, DMA), peroxide initiator (MEKP), thixotropic agents, filler-friendly modifiers, surface gloss improvers, and UV-stability packages. High-quality pigments, calcium carbonate, ATH fillers or silicate mineral blends are commonly dispersed into the resin for desired color, hardness, and translucency.

Key Advantages:

  • High Filler Loading Capability
  • Excellent Brightness and Transparency
  • Low Shrinkage for Crack-Free Surfaces
  • Strong Sanding and Polishing Behavior
  • Consistent Curing Speed
  • Chemical Resistance
  • Durability For High-Traffic Areas.

Customized resin grades are available for fast-gel, low-smell, low-styrene emission, high-clarity onyx casting, thick-layer curing, and reinforced marble formulation.
