1. Introduction

D-250 is a high-quality external release agent for silicone rubber products, providing excellent demolding performance without residue or any sediment. During silicone curing, it quickly achieves clean demolding, improving production efficiency and reducing mold maintenance costs. It ensures excellent lubrication between metal and non-metal surfaces. Thanks to its extremely low surface tension and superior thermal stability, it can be widely applied under harsh temperature conditions. The product is highly stable, safe, and completely non-irritating or harmful, making it fully reliable for use.

2. Advantages

Suitable for all types of silicone products.

Maintains original properties even under large temperature variations.

Resistant to oxidation and largely non-reactive with most chemicals.

Excellent storage stability and easy to handle.

Highly stable at high mold temperatures.

Leaves no residue or contamination on the product surface, reducing costs and improving product quality.

3. Usage Instructions

Dilute the product with clean water and spray directly onto the mold surface.

Dilution ratio should be selected based on the ease of demolding the silicone product.

The amount of release agent sprayed will not cause whitening, cracking, water marks, or oil exudation on the finished product.

Reference dilution ratio: 1:30–40 with filtered or purified water.

4. Precautions

Clean the mold thoroughly before first use to remove any residues of other release agents to ensure effectiveness.

If the dilution ratio is too low, minor oil exudation may occur on certain silicone products. In such cases, increase the water dilution ratio.
