Product Description
SH-730 Silicone release agent
I. Performance and Applications
This product is a solid-containing formulation. 30% The main component of this silicone release agent is a addition‑cure, solvent‑based silicone type, with toluene as the solvent. It cures rapidly upon heating and exhibits stable release performance, excellent adhesion to substrates, and good bath stability. This product delivers relatively strong release force, making it well suited for use with high‑release additives to produce release liners with enhanced peel strength; the coating dries quickly and leaves a high residual tack. It is primarily used for… PET The membrane and certain aluminum foil substrates are coated with silicone, with applications in electronic films, die-cutting, optical films, and thin-film tapes.

SH-730 Silicone Release Coating
Ⅰ. Product Description
SH-730 is a solvent-based, addition-cure silicone release coating base with a 30% solid content, using toluene as the solvent. It features rapid thermal curing, stable peel force, good adhesion to substrates, and excellent bath stability. This product has relatively high peel force, and is suitable usually for use with a heavy release agent to produce release films of high release force. It provides dry coatings with high Subsequent Adhesion Strength . It is mainly intended for silicone coating on PET films and certain aluminum foil substrates with applications in electronic films, die-cutting, optical films, and adhesive tapes .

III. How to Use
P repare the coating solution as follows . Keep the equipment clean . Firstly, d issolve this product in solvents such as toluene or No. 120 solvent oil and mix thoroughly. A dilution ratio of 500 parts solvent to 100 parts base is recommended; then a dd cross-linking agent and stir evenly; and 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, 25 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 and make sure the product is cured as fully as possible.
IV. Packaging and Storage
It is sealed in standard packaging as in 15 kilogram / drum , 150kg / 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.
