Product Description

HONGYE SILICONE non-staining silicone is Platinum cured mold silicone designed for pale, white and transparent resin artwork casting. This color-inert addition curing RTV 2 Silicone Rubber eliminates discoloration and yellowish bleeding onto light-colored castings. Regular silicone easily stains bright crafts, while this inert Mold Making Silicone and Rapid prototyping silicone retains original pure hues for white ornaments, pale sculptures and clear resin decorative mass production.

Product Overview

This non-staining Liquid Mold Silicone is two-component Industrial mold silicone rubber with 1:1 weight mixing ratio. Color-neutral molecular structure will not leach pigment or tiny impurities to contaminate light-toned finished pieces, supporting dual room temperature & heating curing. Widely used for white resin crafts, pale decorative ornaments, clear Prototype silicone , pastel toy molds and light shade rapid prototyping with customizable formulas.

Product Features & Advantages

Pure inert formula never releases colored substances, preventing yellow, grey stains on white & transparent crafts;

Full deep curing without thickness limit, consistent non-staining performance for all mold wall thicknesses;

FDA certified Food grade mold silicone, non-toxic and odorless for food-themed pale decorative crafts;

Moderate fluidity smoothly fills delicate textures without causing uneven color deposition;

High tensile and anti-tear strength, no surface discoloration after hundreds of repeated demolds;

Far superior anti-stain performance than ordinary industrial Mold Silicone rubber;

Customizable transparency, hardness and curing time for all light-tone artwork demands.

Step-by-Step Operation Guide

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

Conduct vacuum defoaming for 2-5 minutes to avoid bubble shadow causing fake stains;

Slowly pour liquid RTV mold silicone into light-color craft casting molds;

Select proper curing mode to avoid thermal-induced internal color precipitation;

Demold gently after complete curing to keep pure original color of finished products;

Seal residual silicone tightly and store indoors away from high temperature aging.
