Die Casting Water-Based Release Agent

Die casting water-based release agents are divided into two types: external release agents and internal release agents. To facilitate the easy removal of products from the mold during the molding process, a coating applied to the surface of the mold is referred to as an external release agent. An ideal release agent should possess good thermal and chemical stability, not corrode the mold, leave no decomposition residues on the mold surface, provide the product with a good appearance, and not affect the product's color, adhesion, or paintability. It should also minimize mold cleaning time, be non-toxic, safe, easy to handle, and cost-effective. This technology provides a die casting water-based release agent and its applications.

This die casting water-based release agent is primarily used for the release of polyurethane products after casting during production, offering excellent release effects for most polyurethane moldings. Its characteristic is that the product uses water as the dispersion phase, forming a water-soluble substance that not only functions to release polyurethane foam but is also biodegradable, producing no harmful substances such as VOCs, making it highly environmentally friendly. Moreover, water, used as a diluent, is non-polluting, readily available, and low-cost.

Technical Specifications of Die Casting Water-Based Release Agent:

1. Appearance: Transparent white homogeneous liquid;

2. Solid Content: ±20%;

3. pH Value: 7-8;

4. Stability: No stratification, no demulsification, no caking.

Main Features:

1. Environmentally Friendly and Non-Polluting: Compared to traditional solvent-based release agents, die casting water-based release agents offer better environmental performance, as they are mainly composed of water, surfactants, lubricants, and other auxiliary components, containing no harmful solvents.

2. Easy to Clean: Die casting water-based release agents are easy to clean, reducing the workload and cost of cleaning during production.

3. Heat and Corrosion Resistance: This coating has strong heat and corrosion resistance, protecting the mold surface from wear and corrosion, thereby extending the mold's service life.

4. Non-Toxic and Odorless: Die casting water-based release agents are harmless to humans and can be used safely.

Usage Method of Die Casting Water-Based Release Agent:

Spray or brush the product directly onto the surface of the item to be released. The recommended dilution ratio for the die casting water-based release agent is 3-10 times, and the specific amount used should be adjusted according to the product system.

Main Functions:

1. Reduce Contact Area: Forms a coating between the mold and the product, reducing the contact area between them, thereby 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.
