Wood form release agent refers to a substance applied to construction formwork before concrete pouring to prevent the formwork from sticking to the concrete surface after pouring, making demolding difficult, or affecting the smoothness of the concrete surface. Its main function is to form a film between the formwork and the concrete surface, isolating the two, hence it is also called a release agent.

The mixing ratio range for wood form release agent to water is typically between 1:3 and 1:10, and the specific ratio can be adjusted according to actual needs. For example, based on the complexity of the casting and on-site conditions, the dilution ratio can be flexibly adjusted. The general principle is that the more complex the casting, the lower the dilution ratio.

The main components of wood form release agent include paraffin, stearic acid, vegetable oil, emulsifying aids, potassium hydroxide, etc., produced through heating, melting, and emulsification processes. Its characteristics include safe operation, minimal environmental pollution, low harm to human health, excellent demolding effects, and biodegradability.

When using wood form release agent, it is recommended to dilute it with tap water and stir. Determine the appropriate dilution ratio based on the complexity of the casting and on-site conditions. For complex castings, it is advisable to spray a uniform layer of diluted solution onto the mold after each demolding to ensure easy demolding for the next pouring.

Wood form release agent has high tensile strength, making it less prone to polishing when frequently in contact with molded resins. This is especially true when the resin contains abrasive mineral fillers or glass fiber reinforcements. Wood form release agent is chemically resistant and does not dissolve when in contact with the chemical components of various resins (particularly styrene and amines). It also has heat and stress resistance, is not easily decomposed or worn, adheres to the mold without transferring to the processed part, and does not hinder painting or other secondary processing operations.

Performance Requirements

The role of wood form release agent is to smoothly separate the cured and formed product from the mold, resulting in a smooth and even product while ensuring the mold can be used multiple times. Specific performance requirements are as follows:

1. Demolding performance (lubricity). Forms a uniform film and ensures dimensional accuracy for complex-shaped molded products.

2. Good continuous demolding performance.

3. The appearance of the molded product is smooth and aesthetically pleasing, without attracting dust adhesion due to the application of sticky wood form release agent.

4. Excellent secondary processability. When the wood form release agent transfers to the molded product, it has no adverse effects on processes such as electroplating, hot pressing, printing, coating, or adhesion.

5. Easy application.

6. Heat resistance.

7. Stain resistance.

8. Good molding performance and high production efficiency.

9. Good stability. When used with compounding agents and materials, its physical and chemical properties remain stable.

10. Non-flammability, low odor, low toxicity.
