Release agent and isolating agent

Mold Release Agent

Mold release agents exhibit strong adhesion, allowing them to preferentially adhere to the mold without transferring to the molded part. They can also modify the resin surface, improving resin flowability and enhancing surface quality. Widely used for demolding in molds and products such as silicone rubber and plastics.

Advantages of Mold Release Agents:

1. Rapid film formation, waterproof冲刷 protection for templates, no residue; waterproof and rust-proof.

2. Excellent release performance, resulting in clean, smooth, and uncontaminated concrete surfaces.

3. Easy demolding. After demolding, the surface remains smooth and even, with neat edges and corners, and no damage.

Mold release agents are also water-soluble, meaning their internal components can fully dissolve in water. Emulsions of compounds like methyl silicone oil are commonly used in industry. These emulsions are water-soluble, offering high heat resistance, easy cleaning, good corrosion and fire resistance, minimal environmental pollution, and relatively safe transportation and storage.

Due to their high water content, water-based mold release agents differ in many aspects from traditional oil-based or solvent-based agents. The demolding effect depends on a film only a few micrometers thick deposited on the cavity surface after spraying. Therefore, there are higher requirements for ingredient selection and application techniques. However, their advantages are significant, including facilitating automated operations, excellent cooling effects, no scaling, improved surface quality of castings, reduced internal porosity, safe usage, clean production, and reduced environmental pollution.

Precautions for Using Mold Release Agents
1. Dilute with water (dilution ratio 3-10 times as appropriate), and mix thoroughly. The dilution ratio can be adjusted based on on-site needs, and diluted solutions should be used up as much as possible in one go.
2. Apply using a spray gun or roller brush. Allow the mold coated with the release agent to dry completely before pouring concrete.
3. Clean the template or mold surface before application.
4. Store at room temperature, protect from freezing and direct sunlight. After opening, ensure the container is sealed and stored properly.
5. Avoid application during rainy conditions. If rain washes away the freshly applied agent, reapply before proceeding.
6. Packaging specification: 50KG drum.

Technical Indicators of Mold Release Agents:

1. Appearance: Transparent white homogeneous liquid;

2. Solid content: ±20%;

3. pH value: 7-8;

4. Stability: No stratification, no emulsion breaking, no clumping.

Usage Method for Mold Release Agents:

Spray or brush the product directly onto the surface requiring demolding. The recommended dilution ratio is 3-10 times, with the specific amount adjusted based on the product system.
