Product Description

HONGYE SILICONE low dust non-powder silicone is cleanroom-grade Platinum cured mold silicone for dust-free precision crafting. This powder-free addition curing RTV 2 Silicone Rubber removes free silica powder to avoid workshop contamination. Unlike dusty Condensation Curing Silicone Mold Rubber, this clean Mold Making Silicone and Rapid prototyping silicone keeps finished products spotless for medical accessories, optical parts and clean-room electronic prototype manufacturing.

Product Overview

This low dust non-powder Liquid Mold Silicone is two-component Industrial mold silicone rubber with standard 1:1 weight mixing ratio. Purified raw material formula eliminates floating powder particles, suitable for strict dust-free workshop environments, supporting dual curing modes. Widely applied to medical accessory molds, optical component Prototype silicone , precision electronic crafts, lab cleanroom rapid prototyping with full customization support.

Reserve original media: low dust non-powder liquid silicone , dust-free cleanroom craft samples, particle dust comparison test, vacuum defoaming operation video, dust-proof sterile packaging for medical and optical component suppliers.

Product Features & Advantages

Fully purified low-dust formula, no free silica powder floating to contaminate precision workpieces;

Full deep curing without thickness limit, clean particle-free surface for all mold thicknesses;

FDA certified Food grade mold silicone, non-toxic and sterile for medical and food cleanroom production;

Smooth pure fluid liquid silicone without powder agglomeration blocking tiny precision gaps;

Reinforced anti-tear strength, no fine powder shedding during repeated demolding;

Far lower particle pollution than ordinary powder-containing industrial Mold Silicone rubber;

Customizable purity grade, transparency and curing time for high-standard cleanroom projects.

Step-by-Step Operation Guide

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

Complete vacuum defoaming for 2-5 minutes to remove micro air bubbles that trap dust particles;

Slowly pour liquid RTV mold silicone into dust-free precision craft molds inside cleanrooms;

Adopt stable low-dust curing process to prevent secondary particle pollution;

Demold softly after full curing to avoid surface powder shedding on precision parts;

Seal leftover silicone and store indoors in dust-proof sealed containers.

Application Scenarios & Buyer Value
