Product Description

HONGYE SILICONE high viscosity thick silicone is heavy-duty Platinum cured mold silicone for large solid casting. This non-sagging addition curing RTV 2 Silicone Rubber uses thickened Silicone raw materials to stop sagging on vertical mold surfaces. Unlike thin-flow Condensation Curing Silicone Mold Rubber, this sturdy Mold Making Silicone and Rapid prototyping silicone holds shape perfectly for vertical wall molds, large concrete ornaments and bulky solid craft production.

Product Overview

This high viscosity Liquid Mold Silicone is two-component Industrial mold silicone rubber with 1:1 weight mixing ratio. Anti-sagging thick formula stays on vertical molds without sliding down, compatible with dual room-temperature and heating curing. Widely applied to large cultural stone molds, vertical sculpture casting, heavy Prototype silicone , concrete component molds and bulky craft rapid prototyping with adjustable custom formulas.

Technical Specifications

Product Features & Advantages

High viscosity anti-sagging formula, no sliding or dripping on vertical mold walls during brushing/pouring;

Full deep curing without thickness limit, stable support for oversized solid thick molds;

FDA certified Food grade mold silicone, non-toxic and odorless for multi-scene large casting;

Balanced thick texture without excessive stirring resistance for manual mold layering;

High tensile and anti-tear strength, resistant to deformation under heavy casting weight;

Better vertical molding stability than ordinary thin-flow industrial Mold Silicone rubber;

Customizable viscosity, hardness and curing time for vertical and oversized casting projects.

Step-by-Step Operation Guide

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

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

Apply or pour thick liquid RTV mold silicone onto vertical and large solid molds;

Select suitable curing mode based on mold size and production cycle;

Demold slowly after full curing to protect large integrated mold structure;

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

Application Scenarios & Buyer Value

Ideal for large solid casting, vertical sculpture molds, cultural stone production, heavy component rapid prototyping silicone and oversized craft molding. This high viscosity silicone avoids sagging mold defects, reduces material waste from dripping, lowers rework rate and cuts production cost for large-scale casting factories.

Certifications and Compliance

This anti-sagging thick silicone passes FDA food safety and ISO quality certifications, complies with international RTV 2 silicone rubber industrial standards, meeting cross-border large construction and art casting material requirements.

Customization Options

We customize viscosity grade, hardness and curing cycle, supplying thick anti-sagging formulas for High transparency mold silicone and vertical large mold projects.

Production Process

High-viscosity silicone raw material screening → thickening modifier blending → constant temperature synthesis → vertical sagging resistance testing → finished product inspection → vacuum sealed packaging.

FAQ

Q1: Will thick viscosity cause incomplete mold filling for complex vertical patterns?

A1: Controlled thickening balances anti-sagging and moderate spread for normal texture replication.

Q2: Can it be brushed layer by layer for large sculpture molds?

A1: Excellent non-sagging performance fits layered brush mold making perfectly.

Q3: Does high viscosity affect deep curing performance?

A1: Platinum addition curing realizes uniform deep curing regardless of thickness.

Q4: Can adjust viscosity for ultra-tall vertical molds?

A4: Higher viscosity anti-sagging customization is available.

Q5: Storage tips to maintain thick texture?

A5: Sealed dry indoor storage within 10-month shelf life, avoid high-temperature softening.
