Addition Curing Silicone for Cultural Stone Veneer - Near-Zero Shrinkage, 25 Shore A

Hong Ye Silicone's HY-E625 is formulated for stone veneer & cladding. Platinum-catalyzed, it delivers near-zero shrinkage, high tear resistance, and food-safe curing. 25 Shore A with 18000-22000 cps viscosity.

Key Features

· - **Platinum Catalyst** — No byproducts; <0.1% shrinkage, no odor, food/skin safe.

· - **High Tear (22 kN/m)** — Longer mold life vs. standard 10-15 kN/m silicones.

· - **Excellent Flow** — Captures fine textures; self-leveling.

· - **Wide Temp (-60°C to 200°C)** — Stable in any environment.

· - **Flexible Ratios (1:1 or 10:1)** — Extended or fast pot life.

· - **FDA, REACH, RoHS** — Food/medical compliant.

· - **800-1000+ casts** — Chemical resistant.

· - Compatible with gypsum, cement, GRC, epoxy, wax, concrete, polyester.
