HONG YE SILICONE Silicone for Cement Garden Statues and Decoration is a professional RTV 2 Silicone Rubber dedicated to mold making for outdoor cement sculptures and decorative parts. As a reliable Liquid Mold Silicone, it is a two-component formula available in Addition Curing Silicone and condensation curing silicone types, with a practical hardness range of 15-40 Shore A. It cures at room temperature and supports heat acceleration for faster production, featuring low shrinkage, smooth fluidity and strong durability. The addition cure grade is food safe, non-toxic and ultra-low shrinkage under 0.1%, ideal for cement, concrete, GRC and related outdoor decoration molding, with flexible packaging and a 12-month shelf life for global bulk procurement.
Product Overview
This Industrial mold silicone rubber is a specially developed liquid silicone for garden cement statue and outdoor decoration mold production, designed to match the harsh use environment of repeated cement casting. It is a two-part flowable material with two mature curing systems for flexible selection: addition cure silicone with a 1:1 mixing ratio, and condensation cure silicone with a 100:3 mixing ratio of base material to curing agent. Both types cure completely at room temperature without additional heating equipment, and can be heated properly to shorten curing time. The addition cure variant stands out with ultra-low shrinkage, high temperature resistance and food safe certification, while both grades offer easy operation and stable performance for large and detailed outdoor decorative mold making.

Product Features & Advantages
This silicone has excellent fluidity and operability, suitable for both pouring and brushing molding processes, able to fully fill every detail of complex garden statues without gaps or bubbles, ensuring clear texture replication of finished castings. It has high tensile and tear strength, making molds durable enough to withstand multiple rounds of cement and concrete casting without tearing, warping or deforming, effectively prolonging mold service life and reducing production costs for batch manufacturing. With moderate hardness and good flexibility, it realizes easy demolding of irregular and complex statue shapes, protecting both the mold and original prototype. The addition cure grade is non-toxic, food safe and high temperature resistant, with ultra-low shrinkage to maintain stable product size, and both types have a long shelf life for convenient storage and use.
How to Use the Product
Step 1: Prepare the target garden statue or decoration prototype, clean the surface thoroughly to remove dust, oil and other impurities, and keep it fully dry, which is crucial for Platinum cured mold silicone to prevent curing inhibition. Step 2: Choose the corresponding curing type, weigh the two components accurately according to the specified ratio, stir slowly and evenly to avoid excessive air bubbles from fast stirring.
Step 3: Conduct vacuum defoaming for the mixed silicone if necessary, then pour or brush the silicone evenly onto the prototype to cover all details and edges completely.
Step 4: Allow the silicone to cure fully at room temperature, or use low heat to speed up curing; for addition cure silicone, strictly avoid contact with sulfur, sulfide, amine materials, organic tin catalysts and uncured condensation silicone during the whole process.
Step 5: Demold gently after complete curing, and the finished mold is ready for cement, gypsum, concrete or GRC casting production.
Application Scenarios
This silicone is mainly used to make molds for cement garden statues, outdoor landscape decorations, concrete ornaments, GRC and GFRC decorative components, serving as a core material for outdoor garden decoration manufacturing. It is also widely applied in making molds for gypsum products, artificial stone, polyurethane and resin crafts, perfectly adapting to the performance requirements of large outdoor decorative parts. It helps manufacturers achieve stable and efficient batch production, maintain consistent product size and delicate texture, improve overall production efficiency, reduce mold replacement frequency and material waste, bringing stable economic benefits for decorative processing enterprises.
Certifications and Compliance
Our silicone for cement garden statues complies with ISO 9001 quality management system and CE certification standards. The addition cure grade has passed food safe testing, non-toxic, odorless and environmentally friendly. All products are classified as non-hazardous chemicals, fully compliant with international production, storage and transportation regulations, suitable for global procurement and cross-border shipping.
Customization Options
We support customized hardness adjustment within 15-40 Shore A to fit different sizes and pattern complexities of garden decoration molds. Provide personalized customization of fluidity, viscosity and curing speed to adapt to pouring or brushing operation techniques. Offer flexible packaging from small sample drums for testing to large bulk drums for mass production, and provide targeted operation guidance for addition cure silicone to avoid curing inhibition and ensure smooth molding.
Production Process & Brand Strength

We have a complete quality control system to ensure stable and consistent performance between batches, and provide professional technical guidance for mold making operations, helping customers avoid common operation errors and ensure high-quality and efficient mold production.
FAQ
Q1: What are the mixing ratios for the two curing systems?
Q2: Why does platinum cure silicone fail to cure sometimes?
A2: It is usually caused by curing inhibition, please clean the prototype thoroughly and avoid contact with sulfur, sulfide, amine, organic tin catalysts and uncured condensation silicone.
Q3: Can we use heat to speed up the curing process?
A3: Yes, both types support room temperature curing, and low-temperature heating can be used to shorten the curing time appropriately.
Q4: How to store this silicone correctly?
A4: Store in sealed original packages in a cool, dry place at 25℃, avoid direct sunlight, with a 12-month shelf life.
Q5: Besides cement, what other materials can this silicone be used for?
A5: It is also suitable for gypsum, artificial stone, resin, polyurethane and other material molding.
