HONGYE SILICONE’s Two Part Liquid silicone rubber Compound is a premium dual-component Addition Curing Silicone, designed for global B2B purchasers in mold making, precision casting, and industrial manufacturing. As a national high-tech enterprise with standardized production and one-stop solutions, this compound consists of flowable Part A (base rubber) and Part B (curing agent), featuring FDA and RoHS certification, non-toxic odorless performance, easy operation, and flexible customization. It supports room/heat curing, deep curing without thickness limits, and high precision, helping purchasers reduce production costs, improve efficiency, and meet diverse mold making and casting needs across industries.
Product Overview
Our Two Part liquid silicone Rubber Compound is a high-performance RTV 2 Silicone Rubber, a professional dual-component organic silicone compound that forms tough, elastic colloids after chemical reaction between Part A and Part B. Adopting advanced addition curing technology, it solves the pain points of ordinary Mold Making Silicone with unstable performance and limited applicability. Unlike condensation curing silicone mold rubber, it achieves shrink-free deep curing, produces no toxic by-products, and has excellent fluidity and mechanical properties, making it suitable for high-precision, multi-scenario mold making and casting, and customizable to meet specific customer requirements.

4. Easy Operation: 1:1 weight ratio, simple stirring for 2~3 minutes, no professional skills required; supports room/heat curing, adapting to small-batch and mass production.
5. Flexible Customization: Hardness, operating time, curing time, and color can be tailored to different needs, from small crafts to large components, without compromising performance.
6. Cost-Effective: High mold cycle life reduces replacement costs; stable batch quality reduces defect rates and rework costs, improving overall production profitability.
How to Use (Step-by-Step Guide)
1. Prepare Part A and Part B of the two-part liquid silicone rubber compound, mix them in a 1:1 weight ratio, stir thoroughly in an irregular direction for 2~3 minutes until uniform, avoiding introducing extra air.
2. Perform vacuum degassing for 2~5 minutes (time varies by viscosity, weight, and vacuum strength) to eliminate bubbles and ensure mold smoothness.
3. Pour the mixed silicone slowly into molds, leveraging good fluidity to fill all details and gaps, ensuring uniform thickness.
4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing; avoid moving the mold during curing to prevent deformation.
5. Store unused Part A and Part B separately in sealed packaging, indoor storage away from sunlight and rain, use within 10 months; avoid contact with N, P, S-containing compounds to prevent curing failure.
Application Scenarios
Our Two Part Liquid Silicone Rubber Compound is widely used in global mold making and casting scenarios, including high-grade simulated food molds, metal crafts, alloy car accessories, epoxy/polyester resin molds, large cement components, cultural stone, concrete molds, and high-precision handboard models. It is also suitable for rapid prototyping and art replication, bringing tangible value: improving production efficiency by 30%+, reducing defect rates by 40%, and supporting diverse customization needs, helping B2B purchasers enhance product competitiveness and gain trust in the global market.
