Product Description

HONGYE SILICONE low exotherm silicone is mild-reaction Platinum cured mold silicone for heat-sensitive master patterns. This low-heat addition curing RTV 2 Silicone Rubber controls reaction peak temperature to prevent thermal damage to delicate masters. Unlike high-exotherm Condensation Curing Silicone Mold Rubber, this gentle Mold Making Silicone and Rapid prototyping silicone protects wood, foam and fragile prototypes during mold making.

Product Overview

This low exotherm Liquid Mold Silicone is two-component Industrial mold silicone rubber with standard 1:1 weight mixing ratio. Controlled catalytic reaction reduces curing heat release, preventing warping or melting of heat-sensitive master models. It supports room-temperature and mild heating curing. Widely applied to foam prototype molds, wooden sculpture casting, delicate master pattern silicone, lightweight craft molds and low-temperature rapid prototyping with full customization support.

Technical Specifications

Curing Type: Platinum cured Addition Curing Silicone; Mix Ratio: 1:1 by weight; Working Time (25℃): 30-40 minutes; Room Curing: 4-5 hours; Heating Curing: 80-120℃ mild fast curing; Temperature Resistance: -60℃~250℃; Shelf Life: 10 months sealed indoor storage; Certification: FDA Food Grade; Core Advantage: Low heat release, mild curing reaction, no thermal damage, full deep curing, safe for fragile masters.

Product Features & Advantages

Low exotherm catalytic formula, low peak temperature avoids damaging heat-sensitive master models;

Full deep curing without thickness limit, no local overheating even for thick silicone layers;

FDA certified Food grade mold silicone, non-toxic and odorless for multi-material craft casting;

Balanced fluid liquid silicone gently wraps fragile masters without impact deformation;

High tensile and anti-tear strength, long service life for repeated mold duplication;

Far milder curing reaction than ordinary high-exotherm industrial Mold Silicone rubber;

Customizable reaction heat level, hardness and color for fragile master mold projects.

Step-by-Step Operation Guide

Blend low exotherm silicone A and B components evenly at 1:1 weight ratio for 2-3 minutes;

Complete vacuum defoaming for 2-5 minutes to eliminate trapped internal bubbles;

Slowly pour liquid RTV mold silicone over heat-sensitive master patterns;

Prioritize room-temperature curing to minimize heat accumulation;

Demold carefully after full curing to protect delicate master surfaces;

Seal leftover silicone and store indoors, avoid accelerated high-temperature reaction.

Application Scenarios & Buyer Value

Perfect for heat-sensitive master mold casting, foam prototype duplication, wooden sculpture molds, lightweight craft production and low-exotherm rapid prototyping silicone. This low exotherm silicone prevents master pattern melting, warping and damage, saves expensive master remake costs and enables duplication of fragile handmade artworks.

Certifications and Compliance

This mild-reaction silicone holds FDA safety and ISO quality certifications, complies with international RTV 2 silicone rubber standards, meeting cross-border delicate prototype molding material requirements.

Customization Options

We support exotherm level, transparency and viscosity customization, supplying low-heat formulas for High transparency mold silicone and fragile master duplication projects.

Production Process

Low-exotherm silicone raw material purification → mild catalyst blending → reaction temperature calibration → thermal impact testing → finished product inspection → vacuum sealed packaging.

FAQ
