Product Description

HONGYE SILICONE self-releasing silicone is Platinum cured mold silicone designed for effortless demolding. This low-adhesion addition curing RTV 2 Silicone Rubber uses special release additives to reduce adhesion between silicone and cast resin. Unlike sticky Condensation Curing Silicone Mold Rubber, this practical Mold Making Silicone and Rapid prototyping silicone avoids surface tearing, cuts repair work and raises yield for mass craft production.

Product Overview

This self-releasing Liquid Mold Silicone is two-component Industrial mold silicone rubber with 1:1 weight mixing ratio. Built-in internal release agent removes the need for extra release spray. It supports room temperature and heating dual curing, widely applied to resin crafts, Toy mold silicone , Prototype silicone , cultural stone casting and daily rapid prototyping, with adjustable custom formulas.

Technical Specifications

Curing Type: Platinum cured Addition Curing Silicone; Mix Ratio: 1:1 by weight; Working Time (25℃): 30-40 mins; Room Curing: 4-5 hrs; Heat Curing: 80-120℃ fast molding; Temp Resistance: -60℃~250℃; Shelf Life: 10 months sealed indoor storage; Certification: FDA Food Grade; Core Advantage: Built-in release property, low adhesion, clean demolding, no surface damage, deep curing.

Product Features & Advantages

Built-in self-release formula, no extra release agent required to save production cost;

Full deep curing without thickness limit, consistent low adhesion for all mold sizes;

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

Balanced fluid liquid silicone flows smoothly without separating release components;

High tensile and anti-tear strength, zero chipping during repeated demolding cycles;

Cleaner demolding performance than ordinary industrial Mold Silicone rubber;

Customizable release strength, hardness and color for different casting materials.

Step-by-Step Operation Guide

Mix self-releasing silicone A and B evenly at 1:1 weight ratio for 2-3 minutes;

Vacuum defoam mixed silicone for 2-5 minutes to eliminate internal micro bubbles;

Pour liquid RTV mold silicone steadily into craft casting molds;

Select suitable curing mode based on production line schedule;

Demold effortlessly after full curing without scratching finished surfaces;

Seal residual silicone tightly and store indoors away from direct sunlight and rain.

Application Scenarios & Buyer Value

Ideal for resin craft casting, mass toy mold silicone, cultural stone production and rapid prototyping silicone. This self-releasing silicone eliminates additional release agent expense, reduces product surface damage defects, shortens post-processing time and improves overall factory production efficiency.

Certifications and Compliance

This low-adhesion silicone passes FDA food safety and ISO quality certifications, complies with international RTV 2 silicone rubber industrial standards, meeting cross-border resin craft manufacturing material standards.

Customization Options

We customize release degree, viscosity and curing cycle, supplying self-release formulas for High transparency mold silicone and various resin casting projects.

Production Process

High-purity silicone raw material screening → internal release additive blending → constant temperature synthesis → adhesion testing → finished product inspection → vacuum sealed packaging.

FAQ

Q1: Does built-in release affect bonding with master models?

A1: It only reduces adhesion to cast resin, no separation from original master molds.

Q2: Can it work with epoxy, polyester resin and concrete?

A1: Matches most common casting mediums for clean demolding.

Q3: Will release effect fade after dozens of demolds?

A1: Uniform internal formula maintains stable release performance long-term.

Q4: Can adjust release force for delicate thin crafts?

A4: Low-release soft formula customization is available.

Q5: Storage requirement for unused silicone?

A5: Sealed dry indoor storage, valid shelf life 10 months.
