Platinum-Cure Liquid Silicone Rubber (LSR) for High-Detail Silicone Molds – Food-Safe, Medical & Industrial Grade – Fast Curing, 0.1% Shrinkage

RTV-2 platinum-cured 1:1 addition-type liquid silicone rubber

Introduction
Platinum-cure Liquid Silicone Rubber (LSR) is the premium choice for crafting high-precision, durable silicone molds across industries. Designed for professionals and hobbyists alike, our LSR combines FDA-compliance, ultra-low shrinkage, and exceptional tear resistance to replicate intricate details flawlessly—whether for food production, medical prototypes, or artistic resin casting.

Key Features & Benefits

1. Unmatched Precision & Durability
- Ultra-Low Shrinkage (<0.1%): Ensures molds retain exact dimensions of the original model, critical for multi-part assemblies or tight-tolerance parts.
- Shore A 10–70 Hardness Range: Soft (Shore A 10–30) for flexible molds (e.g., chocolate, wax) or firm (Shore A 40–70) for rigid supports (e.g., concrete, epoxy).
- 500+ Cycle Lifespan: Resists tearing even with deep undercuts or frequent demolding.

2. Industry-Specific Compliance
- Food-Grade: Safe for direct contact with chocolate, ice, and baked goods.
- Industrial Stability: Withstands -50°C to 250°C, ideal for automotive gaskets or high-temperature resin casting.

3. User-Friendly Processing
- Fast Cure Time (4-15h): Adjustable with temperature (accelerated at 60–80°C).
- Self-Deairing Formulations: Minimizes bubbles without vacuum degassing—perfect for beginners.
- Non-Inhibiting Versions: Compatible with 3D-printed SLA/resin masters, wax, and clay.

General parameters

Applications
- Culinary: Custom cake decorations, candy molds, ice cube trays.
- Art & DIY: Resin jewelry, concrete planters, soap molds.
- Medical: Anatomical models, hearing aid shells.
- Industrial: Rapid prototyping, low-volume production of rubber parts.

Main feature :

1. Environmentally friendly, non-toxic, tasteless, non-corrosive, passed FDA food grade, MSDS, ROSH and other certifications.

2. Low viscosity, good fluidity, convenient operation and easy pouring; it can be cured at room temperature or heated.

3. Excellent physiological inertia, waterproof, ozone resistance and aging resistance, high tensile toughness, and many mold turning times.

4. High chemical stability, high and low temperature resistance, can be used for a long time and maintain its performance at -55°C to 220°C.

5. No low molecules are released during the cross-linking process, so the volume remains unchanged, the shrinkage rate is as low as 0.1%, and the precision is high.

Packing and shipping:
10Kg/set (A component 5Kg +B component 5Kg)
40Kg/set (A component 20Kg +B component 20Kg)
50Kg/set (A component 25Kg +B component 25Kg)

Packed in iron drum or plastic drum, transported as non-dangerous goods, sealed at room temperature 25°C, and protected from acid and alkali impurities, the storage period is 12 months.

Precautions :

1. Do a small amount of testing before use, and then put it into use.

2. Do not add color or powder to the silica gel at will before testing. Do not contact with water, acid, alkali or other organic matter containing sulfur, phosphorus and nitrogen, so as not to affect the curing of silica gel.

3. This product is a platinum catalyst silica gel, which cannot be in contact with condensation type silica gel. Before using the silica gel, tools and containers need to be cleaned with thinner water.

4. If you need to color, please add the color paste to component B by 2/1000, and stir evenly.
