SH-640 Silicone Release Agent
This product is a platinum-catalyzed, solvent-free silicone release agent. It cures rapidly upon heating, exhibits low extractability and high residual tack, and delivers consistent release performance, excellent substrate adhesion, and outstanding bath stability, while providing effective resistance to penetration and oil‑repellent properties. It is primarily used for siliconizing food-grade or hygiene paper with significant permeation issues, or in applications requiring a particularly smooth coating.

III. Usage References
It is recommended to prepare the coating solution according to the following steps. The equipment should be clean. First, add the main component. Then, add the crosslinking agent and stir thoroughly. Finally, slowly introduce the catalyst while stirring until well mixed. Under normal conditions, the shelf life of the coating solution is… 6 Hour.
The filtered coating solution is uniformly applied to the substrate and then cured by heating in an oven. Refer to the temperature and duration used during laboratory curing tests: 140℃*20s 。
Precautions for Use:
1. This product is susceptible to contamination by peroxides and other substances, such as organotin compounds, sulfur-containing materials, and amines. Please clean all mixing and coating equipment, and use dedicated containers whenever possible.
2. To ensure optimal performance of this product, it is essential to optimize the application process to achieve complete curing.
IV. Packaging and Storage Transportation
Standard packaging 20kg/ Bucket, 200kg/ Drums; packaging can be customized upon request. Please store in a cool, dry, well-ventilated area and keep tightly sealed. From the date of manufacture, this product is… 30℃ The following shelf life is: 12 months.
SH-640 Silicone Release Coating
Ⅰ. Product Description
SH-640 is an addition-curing and solvent-free Silicone Release Coating. It features rapid thermal curing, low extraction rate, and high Subsequent Adhesion Strength . It is also characterized by stable peel force, good adhesion to substrates, excellent bath stability, and good anti-penetration as well as oil resistance. It is mainly used for silicone coating on highly permeable food paper or hygiene paper, or products requiring a relatively smooth coating.

III. How to Use
P repare the coating solution as described later. Keep the equipment clean . Firstly, add base component. Then a dd cross-linking agent and stir evenly . Finally, a dd catalyst slowly and stir evenly . The typical pot life of the coating solution is 6 hours.
Apply the filtered coating solution evenly onto the substrate, and then cure it in the oven , like under laboratory conditions, 2 0 seconds at 140 °C .
Note:
- This product is easily contaminated by peroxides, amino compounds, other substances that contains, for example, organotin or sulfur. Therefore, please clean all the mixing and coating equipment and use an exclusive container whenever possible.
- For better use, please adjust the process to make sure the product is cured as fully as possible.
IV. Packaging and Storage
It is sealed in standard packaging as in 20kg / drum , 200kg / drum , or customized as per customer request. Please store it in a cool, dry and well-ventilated place in unopened packag ing . The shelf life is 12 months below 30 °C.
