Water-based rubber release agent

Water-based Rubber Release Agent

Water-based rubber release agents are also water-soluble release agents, meaning the internal components of the release agent can fully dissolve in water. Emulsions of compounds such as methyl silicone oil are commonly used in industry. The emulsion is water-soluble and can achieve high heat resistance, easy cleaning, good corrosion resistance, fire resistance, minimal environmental pollution, and relatively safe transportation and storage.

Due to the high water content, water-based release agents differ in many aspects from traditional oil-based or solvent-based release agents. The release effect of water-based rubber release agents depends on a film only a few micrometers thick deposited on the cavity surface after spraying. Therefore, there are higher requirements for the selection of components and the use of processes. However, its advantages are also evident, facilitating automated operations, good cooling effect, no scaling, improved surface quality of castings, reduced internal pores, safe use, clean production, and reduced environmental pollution.

Water-based rubber release agents have 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 surface quality. They are widely used in molds and for the release of products such as silicone rubber and plastics.

Precautions for Using Water-Based Rubber Release Agents
1. Dilute with water (dilution ratio 3-10 times as appropriate), and mix evenly. The dilution ratio can also be adjusted according to on-site needs. Try to use the diluted mixture all at once.
2. Apply using a spray gun or roller brush. After applying the release agent, wait until the model is completely dry before pouring concrete.
3. Clean the template or model 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 construction during rainy weather. If rain washes away the freshly applied coating, reapply before proceeding.
6. Packaging specification: 50KG drum.

Advantages of Water-Based Rubber Release Agents:

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

2. Excellent isolation performance, resulting in clean, flat, and uncontaminated concrete surfaces.

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

Main Functions:

1. Reduce contact area: Forms a coating between the mold and the product, reducing the contact area and preventing adhesion.

2. Improve separation: Enhances the separation between the mold and the product, reducing the likelihood of material residue on the mold, ensuring product quality and production efficiency.
