Product Description

HONGYE SILICONE ultra thin layer silicone is thin-wall molding Platinum cured mold silicone for miniature slim crafts. This ultra-film forming addition curing RTV 2 Silicone Rubber features ultra-thin uniform film formation without shrinkage or cracking. Unlike thick-layer Condensation Curing Silicone Mold Rubber, this thin-film Mold Making Silicone and Rapid prototyping silicone creates flawless slim miniature ornaments, thin skin simulation and ultra-thin wall model products.

Product Overview

This ultra thin layer Liquid Mold Silicone is two-component Industrial mold silicone rubber with standard 1:1 weight mixing ratio. Formulated for 0.1–3mm thin wall mold casting, it maintains complete integrity without cracking, supporting dual curing modes. Widely applied to miniature thin craft molds, slim simulation skin body silicone, ultra-thin Prototype silicone , delicate jewelry molds and thin-wall rapid prototyping with full customization support.

Product Features & Advantages

Special thin-film crosslink formula, complete continuous thin silicone layer without fracture;

Full deep curing even for sub-millimeter thin walls, no incomplete curing local defects;

FDA certified Food grade mold silicone, non-toxic and safe for miniature food and jewelry crafts;

Fine uniform fluid liquid silicone spreads evenly to form seamless ultra-thin mold layers;

High tensile and anti-tear strength, thin film will not split during demolding;

Superior thin-wall forming stability than ordinary thick industrial Mold Silicone rubber;

Customizable thin-layer thickness range, transparency and curing time for slim miniature crafts.

Step-by-Step Operation Guide

Blend ultra thin layer silicone A and B components evenly at 1:1 weight ratio for 2-3 minutes;

Complete strict vacuum defoaming for 2-5 minutes to eliminate tiny bubbles that break thin films;

Spread thin liquid RTV mold silicone evenly on miniature thin-wall master molds;

Adopt mild low-temperature curing to avoid thin layer thermal shrinkage cracking;

Demold extremely gently after full curing to protect fragile ultra-thin mold walls;

Seal leftover silicone and store indoors, avoid heavy extrusion during storage.

Application Scenarios & Buyer Value

Perfect for ultra-thin miniature craft casting, slim jewelry molds, thin simulation skin accessories, miniature rapid prototyping silicone and delicate thin-wall ornament production. This ultra thin layer silicone solves thin-wall cracking and incomplete forming defects, raises miniature craft surface fineness, increases product added value and helps suppliers occupy high-end miniature craft market.

Certifications and Compliance

This thin-film molding silicone holds FDA safety and ISO quality certifications, complies with international RTV 2 silicone rubber precision molding standards, meeting cross-border miniature thin-wall craft material requirements.

Customization Options

We support minimum thin film thickness, hardness and viscosity customization, supplying ultra-thin forming formulas for High transparency mold silicone and all slim miniature molding projects.

Production Process

Thin-film silicone raw material purification → low-shrink thin layer modifier blending → homogeneous crosslink synthesis → thin-wall cracking resistance testing → precision inspection → vacuum sealed packaging.
