Liquid Silicone for Artificial Stone: How to Choose the Best RTV-2 Silicone for Mold Making

2026-08-21

Berita perusahaan terbaru tentang Liquid Silicone for Artificial Stone: How to Choose the Best RTV-2 Silicone for Mold Making

The production of facade panels, facing tiles, and decorative stone requires high-performance flexible matrices. Today, liquid silicone for molds (RTV-2) stands as the gold standard in the artificial stone manufacturing industry.

As a direct manufacturer of industrial compounds, we break down the critical criteria for choosing the right material for your business.

1. Why RTV-2 Silicone for Culture Stone?

Architectural and culture stones feature deep, intricate textures like slate, split bricks, or natural boulders. Two-component cold-curing silicone offers:

  • Flawless Detail Reproduction: Captures the finest pores and surface roughness of the master model.

  • Easy Demolding: Finished gypsum or concrete tiles release smoothly without damaging sharp corners or edges.

  • Low Shrinkage: Dimensional stability ensures your tiles stay uniform batch after batch.

2. Key Selection Criteria

  • Shore Hardness (Shore A): For large-format wall panels and heavy cement mixes, a hardness of 30–35 Shore A is optimal. For smaller gypsum tiles, 20–25 Shore A provides greater elasticity.

  • Viscosity: Low-viscosity formulations mix easily (manually or mechanically) to minimize air bubble formation.
