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.
Ⅱ. Technical Data
Item | Index |
Appearance | Colorless transparent liquid |
Viscosity (25℃, cp) | 300~500 |
Active Ingredient Content (%) | 100 |
Test Substrate | PE-coated paper |
Silicone Coat Weight (g/m2) | 1 |
Rapid Release Force (20min, gf/25mm) | 5~8 |
Aged Release Force (70℃, 24h, gf/25mm) | 10~15 |
Subsequent Adhesion Strength (70℃, 24h, %) | ≥90 |
III. How to Use
Prepare the coating solution as described later. Keep the equipment clean. Firstly, add base component. Then add cross-linking agent and stir evenly. Finally, add 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, 20 seconds at 140℃.
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 packaging. The shelf life is 12 months below 30℃.
