HONG YE SILICONE high-strength stone molding silicone is specially developed for mass production of cement and stone products. It solves the pain point of fine pattern damage in heavy cement product molding, with low linear shrinkage, excellent fluidity, and deep vulcanization performance. Featuring high tear resistance, aging resistance, and acid-alkali resistance, it enables perfect pattern replication and repeated use, significantly reducing production costs. Compliant with ISO9001, CE, and UL standards, this RTV-2 silicone rubber supports customization and serves global markets, ideal for large stone, gypsum components, cultural stone, and sandstone carving production.
Product Overview
HONG YE SILICONE stone molding silicone is a professional RTV-2 silicone rubber tailored for heavy cement and stone product manufacturing. Targeting the problem that hard mold materials struggle to replicate fine surface patterns without damage, our Addition Curing Silicone achieves synchronous vulcanization from inside to outside, no small-molecule by-products, and no stickiness even in sealed or high-temperature environments. As a core product of our Industrial mold silicone rubber series, it integrates low viscosity, high fluidity, and high strength, ensuring stable performance for mass production and long-term use.

Product Features & Advantages
1. Precise Replication: Low linear shrinkage ensures 1:1 reproduction of fine patterns and grains, solving the problem of pattern damage in traditional molds.
2. Superior Fluidity: Low viscosity enables easy pouring and brushing, fully filling mold details without bubbles.
3. Deep Vulcanization: No small-molecule by-products, synchronous vulcanization, avoiding stickiness and ensuring uniform curing.
4. Durable Performance: High tear resistance and aging resistance extend mold service life, supporting hundreds of replications.
5. Cost-Effective: Reusable design and stable quality reduce mold replacement frequency and production costs.
Usage Instructions
1. Mix silicone and curing agent in the specified ratio (confirm with us for exact proportion) and stir evenly.
2. Vacuumize the mixture for ≤10 mins; for no vacuum equipment, choose low-viscosity, long-operation-time silicone for self-degassing.
3. Prepare external mold with rubber/wooden boards; use gypsum filling or resin+glass fiber cloth brushing (2-3 layers) for reinforcement.
4. Pour or brush the silicone onto the product, then cure as required. Store the mold for 24 hrs before formal use.
Application Scenarios
Ideal for manufacturing silicone molds for large stone, gypsum products, cement components, cultural stone, background walls, and sandstone carvings. Widely used in construction decoration, landscape engineering, and cultural relic restoration industries. It helps procurement partners improve production efficiency, ensure product consistency, and reduce mold investment costs.
Certifications and Compliance
The product has passed ISO9001 quality management system certification, CE, and UL safety certifications, complying with international environmental and safety standards. It is non-toxic, odorless, and meets the requirements of global industrial production, ensuring smooth customs clearance and use in target markets.
Customization Options
We offer OEM services and support customization of viscosity, curing time, hardness, and tear strength according to specific production needs of customers. Whether for small-batch prototypes or large-scale mass production, we can tailor solutions to match your process requirements.
Production Process & Quality Control
Our stone molding silicone is produced through raw material selection (high-purity Silicone raw materials), precise formula blending, vacuum mixing, quality testing, and automated filling. Each batch undergoes pre-production sampling and final shipment inspection to ensure stable performance. With 20 production lines and professional QC teams, we guarantee consistent product quality.
FAQ
1. What is the service life of the mold?
Under proper use, it can be replicated 200-500 times, depending on product complexity and usage conditions.
2. Can it be used for food contact products?
3. How to adjust curing speed?
Adjust curing agent dosage according to temperature: reduce dosage in high temperature, increase slightly in low temperature.
