Product Description
SH-620 Organosilicone release agent
I. Performance and Applications
This product is an addition-cure, solvent-free silicone release agent. It offers low release force, rapid thermal curing, and a low extractable‑solids content, while providing consistent peel strength, excellent substrate adhesion, and outstanding bath stability. It is primarily used for siliconizing coated paper and glassine paper where mild release performance is required. For coated paper, its main applications are kraft‑coated papers, with end‑use markets including wallpaper and footwear materials. For glassine paper, it is mainly employed in high‑speed automated labeling and similar applications.

Three , use Reference
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 add the catalyst and mix well. 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.

SH-620 Silicone Release Coating
Ⅰ. Product Description
SH-620 is an addition-curing and solvent-free Silicone Release Coating. It features light release force, rapid thermal curing and low extraction rate. It also offers stable peel force, good adhesion to substrates, and excellent bath stability. It is mainly used for silicone coating on coated paper and glassine paper that requires light release force. For coated paper, it focuses on kraft release paper with end products such as wallpaper and shoe materials. For glassine paper, end products are primarily high-speed automatic labeling.

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.
