High tear strength RTV2 liquid silicone: the ideal mold material for complex cultured stone textures.

High-tear-strength RTV2 liquid silicone sealant is ideal for deep molding and complex 3D textures in cultured stone, ensuring tear-free demolding. It is suitable for stacked stone, 3D wall tiles, and irregularly shaped stone production.

Cultured stone products often feature deep moldings, sharp edges, and complex 3D textures. These structures can easily tear molds with insufficient strength during demolding. High-tear-strength RTV2 liquid silicone sealant is specifically designed to handle these complex geometries.

Key Features & Applications

Our high-end RTV2 liquid silicone sealant boasts a tear strength of 28–35 kN/m, allowing molds with deep moldings and fine protrusions to be easily flipped during demolding without tearing. This is particularly crucial for factories producing the following products:

• Stacked stone finishes with interlocking structures
• 3D decorative wall tiles with embossed patterns
• Irregularly textured river pebbles and field stone designs
• Slate and sandstone panels with natural cleavage

The two-component system (base material + hardener) cures at room temperature with a linear shrinkage rate of less than 0.1%, ensuring precise mold dimensions from the first pour to the last. Factory customers can control the curing speed by adjusting the hardener ratio, flexibly matching production schedules.

We offer various packaging sizes of 20kg, 200kg, and 1000kg, and provide a complete set of technical documents including MSDS and product specification sheets with each shipment to meet import customs clearance requirements in the Russian and Central Asian markets.
