Product Description

HONGYE SILICONE acid & alkali resistant silicone is anti-corrosion Platinum cured mold silicone for harsh industrial casting. This chemically stable addition curing RTV 2 Silicone Rubber adopts modified Silicone raw materials, resisting acid, alkali and chemical solvent erosion. Different from corrosive-susceptible Condensation Curing Silicone Mold Rubber, this durable Mold Making Silicone and Rapid prototyping silicone maintains intact mold performance for cement, chemical and corrosive craft manufacturing.

Product Overview

This acid and alkali resistant Liquid Mold Silicone is two-component Industrial mold silicone rubber with 1:1 weight mixing ratio. Developed for harsh corrosive working environments, it enhances chemical inertness while retaining dual curing functions. It fits concrete cultural stone molds, chemical crafts, alloy Prototype silicone , wear-resistant Toy mold silicone and corrosive medium rapid prototyping, and supports formula customization.

Product Features & Advantages

Modified anti-corrosion formula, resistant to cement alkaline erosion and weak acid corrosion;

Complete deep curing without thickness limit, no cracking under long-term chemical soaking;

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

Stable fluid liquid silicone, not deteriorated by chemical additives during pouring;

Reinforced anti-tear strength, anti-abrasion to extend service life of harsh-condition molds;

Better chemical stability than ordinary industrial Mold Silicone rubber;

Customizable corrosion resistance, color and curing time for extreme working scenarios.

Step-by-Step Operation Guide

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

Implement vacuum defoaming for 2-5 minutes to remove internal micro bubbles;

Pour liquid RTV mold silicone into corrosive-resistant casting molds steadily;

Choose room temperature or heating curing according to industrial production demands;

Demold gently after full curing to avoid surface abrasion damage;

Seal residual silicone and store indoors, keep away from strong corrosive reagents.

Application Scenarios & Buyer Value

Suitable for harsh environment casting, concrete cultural stone molding, chemical crafts, rapid prototyping silicone and corrosion-resistant toy mold silicone production. This anti-corrosion silicone reduces mold damage failure rate, cuts mold replacement cost, adapts complex industrial working conditions, and lowers after-sales maintenance risks for global manufacturers.

Certifications and Compliance

This chemical-resistant silicone passes FDA safety and ISO industrial certification, complies with international RTV 2 silicone rubber corrosion resistance standards, meeting cross-border harsh industrial production material requirements.

Customization Options

We support customization of corrosion resistance grade, hardness and viscosity, providing anti-erosion formulas for High transparency mold silicone and special chemical casting projects.

Production Process

Anti-corrosion silicone raw material screening → inert ingredient blending → chemical stability reinforcement synthesis → corrosion durability testing → finished product inspection → vacuum sealed packaging.
