Product Description

HONGYE SILICONE bubble resistant silicone is Platinum cured mold silicone optimized for bubble-free surface casting. This anti-foaming addition curing RTV 2 Silicone Rubber uses special defoaming Silicone raw materials to suppress micro bubble generation during mixing and pouring. Unlike bubble-prone Condensation Curing Silicone Mold Rubber, this premium Mold Making Silicone and Rapid prototyping silicone minimizes surface pits, delivering perfect smooth finish for high-end crafts and decorative ornaments.

Product Overview

This bubble resistant Liquid Mold Silicone is two-component Industrial mold silicone rubber with 1:1 weight mixing ratio. Built-in anti-foam additives reduce bubble formation, lowering dependence on long vacuum defoaming. It supports room-temperature and heating dual curing. Widely used for high-gloss resin crafts, art ornament molds, Prototype silicone , Toy mold silicone and premium rapid prototyping, with customizable formulas.

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℃ fast curing; Temperature Resistance: -60℃~250℃; Shelf Life: 10 months sealed indoor storage; Certification: FDA Food Grade; Core Advantage: Anti-bubble, low foaming tendency, smooth flawless surface, full deep curing, easy vacuum processing.

Product Features & Advantages

Specially modified anti-foam formula greatly reduces micro bubbles during mixing and pouring;

Full deep curing without thickness limit, consistent anti-bubble performance for thick molds;

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

Stable fluid liquid silicone flows smoothly without trapping air in intricate textures;

High tensile and anti-tear strength, maintains smooth surface after repeated demolding;

Better anti-bubble performance than ordinary industrial Mold Silicone rubber;

Customizable viscosity, color and curing time for flawless-surface casting projects.

Step-by-Step Operation Guide

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

Carry out vacuum defoaming for 2-5 minutes to remove residual micro bubbles;

Pour liquid RTV mold silicone slowly into craft molds to avoid air entrainment;

Select suitable curing mode based on production schedule;

Demold gently after full curing to preserve smooth finished surfaces;

Seal residual silicone tightly and store indoors away from extreme temperatures.

Application Scenarios & Buyer Value
