Note: 1. The above data are typical values for reference only, not guaranteed technical specifications; actual performance may vary slightly by production batch. 2. Attention: The product contains toluene as a diluent and has a low closed-cup flash point (5℃), so it should be stored and used in a well-ventilated environment, away from open flames and high-temperature sources to avoid fire or explosion risks. 3. It is recommended to confirm the latest product specification sheet before use for accurate parameter guidance.

Ⅲ. Primary Applications

Label & Paper Industry: Primary coating for self-adhesive labels and high-quality release papers.
Adhesive Protection: Used for manufacturing protective films and liners for various industrial tapes.
Substrate Coating: Suitable for various substrates requiring a silicone release layer.

Ⅳ. Packaging and Storage

The product should be stored in its original airtight container at -20℃ to +30℃. The expiration date (used before “month-year” is clearly indicated on the label of each barrel. The fact that the storage period exceeds the best period indicated on the label does not mean that the product is no longer usable. But in this case, in order to guarantee the quality of the product, it is necessary to re-check the relevant properties of the Product.

Ⅴ. Usage Reference

It is recommended to prepare the coating solution according to the following steps. The equipment should be clean and dry.

1.Disperse the release agent in heptane, toluene or other aliphatic or aromatic solvents. It is recommended that the solid content after dilution is 2 – 10%.

2.Add a cross – linking agent. If an anchoring agent is required, add the anchoring agent. Stir until uniform.

3.Finally, slowly add the catalyst until uniform stirring is achieved.

4.Optional components include: light – release additives and heavy – release additives.

5.Use the filtered coating solution to uniformly coat the substrate through a suitable coating head, and then enter the oven for curing. The oven temperature is set at 100 – 160°C, and the residence time in the oven is several seconds to dozens of seconds.
