Spraying Release Agent

The spraying method involves using a spray gun to evenly apply the release agent onto the mold surface. This method improves work efficiency and is particularly suitable for large-area mold treatment. Spraying ensures a more uniform coverage of the release agent on the mold surface, reducing missed spots and waste while allowing better control over the amount used. Additionally, the spraying method reduces manual operation and lowers labor intensity.

Selection Method

?Work Efficiency?: If large-area molds need to be treated, the spraying method is more efficient.

?Cost?: The spraying method requires specialized spray gun equipment, which involves a higher initial investment, but it can save labor and time costs in the long run.

?Applicable Scenarios?: For complex mold structures, the brushing method may be more flexible, while for large flat surfaces, the spraying method is more suitable.

Spraying Release Agent: Primarily composed of imported polymer materials, various additives, super-hydrophilic leveling agents, and other raw materials. The spraying release agent is colorless, odorless, non-polluting, and results in a smooth and flat product surface without affecting subsequent coloring or other processing techniques. It does not impact the adhesion or appearance of the finished product. It facilitates easy demolding without damaging the mold and is widely used for demolding and release treatment of aluminum molds, steel molds, wooden molds, silicone molds, glass, ceramic molds, and plastic molds. The spraying release agent can be diluted 3-10 times with water. It is suitable for anti-stick treatment on the surfaces of various cement product molds, ensuring easy demolding without damaging the mold. It is also used for anti-stick isolation treatment on石膏 mold surfaces, surface treatment of magnesium oxide product molds, lime product molds, and other water-diluted or water-mixed product surfaces. The spraying release agent offers excellent demolding effects and release isolation properties. It has a low comprehensive cost, leaves no honeycomb pores or grease on the surface, is colorless and non-yellowing, and has no irritating odor.

Spraying release agent is a functional substance介于 molds and finished products. It has chemical resistance and is not dissolved when in contact with the chemical components of different resins (especially styrene and amines). It also possesses 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. Due to the rapid development of processes such as injection molding, extrusion, calendering, compression molding, and lamination, the usage of spraying release agents has significantly increased.

Technical Specifications of Spraying 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.

Usage Method of Spraying Release Agent:

Directly spray or brush the product onto the surface of the item to be demolded. The recommended dilution ratio for the spraying release agent is 3-10 times, and the specific amount used should be adjusted according to the product system.

Performance Characteristics of Spraying Release Agent:

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

The spraying 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. It has chemical resistance and is not dissolved when in contact with the chemical components of different resins (especially styrene and amines). It also possesses 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.
