Composite Mold Release Agent

Composite mold release agent is a functional substance that acts between the mold and the finished product. It possesses chemical resistance, remaining undissolved when in contact with various resin chemical components (particularly styrene and amines). It also exhibits heat and stress resistance, being resistant to decomposition or wear. The composite mold release agent adheres to the mold without transferring to the processed part, thereby not interfering with spraying or other secondary processing operations. Due to the rapid development of processes such as injection molding, extrusion, calendaring, compression molding, and lamination, the usage of composite mold release agents has significantly increased.

Performance Requirements

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

1. Release performance (lubricity). Forms a uniform film and ensures dimensional accuracy even for complex-shaped molded parts.

2. Excellent sustained release performance.

3. The appearance of the molded part is smooth and aesthetically pleasing, without attracting dust due to the application of sticky composite mold release agents.

4. Superior secondary processability. When the composite mold release agent transfers to the molded part, it has no adverse effects on processes such as electroplating, hot pressing, printing, coating, or bonding.

5. Easy application.

6. Heat resistance.

7. Stain resistance.

8. Good molding performance and high production efficiency.

9. Excellent stability. When used with compounding agents and materials, it maintains stable physical and chemical properties.

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

Usage Method of Composite Mold Release Agent:

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

Performance Characteristics of Composite Mold Release Agent:

The composite mold release agent is resistant to acids, alkalis, and hard water, highly water-soluble, and has stable emulsion properties. It can be diluted with water in any proportion without layering, demulsification, or clumping. It has a long shelf life, high solid content, and excellent dispersibility. It is used for mold release in industries such as aluminum molds, steel molds, wooden molds, silicone molds, glass, ceramic molds, plastic molds, rubber, metal, and plastics. The composite mold release agent gives the released product a smooth, wear-resistant, and anti-adhesive surface with a pleasant feel.

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 possibility of material residue on the mold and ensuring product quality and production efficiency.

The composite mold release agent combines the characteristics of similar domestic and international products. It is a viscous emulsion synthesized through advanced molecular synthesis technology and special processes using high molecular polymers and various chemically active substances. It offers fast film formation and easy release. The composite mold release agent is widely applicable in large cement bridge factories, highways, bridges, rails, subway segments, cement pipe factories, high-rise building concrete aluminum formwork construction, steel formwork construction, wooden formwork construction, bamboo plywood molds, resin molds, and ground molds.
