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

Prepare the coating solution as followsKeep the equipment clean. Firstly, dissolve 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 add cross-linking agent and stir evenly; and finally add catalyst slowly and stir evenlyThe 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.

Note:

  1. 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.
  2. 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 15kg/ drum150kg/ 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℃.
