SH-630 Silicone Release Coating

Ⅰ. Product Description

SH-630 is an addition-curing and solvent-free Silicone Release Coating. It features rapid thermal curing, low extraction rate, stable peel force, good adhesion to substrates and excellent bath stability. It also offers good curing performance on a wide range of paper substrates. It is a versatile release agent used for silicone coating on most conventional release papers, and characterized by good compatibility with most adhesives. Applications include release papers for pressure-sensitive adhesive tapes (PSA) and labels, single-sided and double-sided industrial release papers, base coating for high-tech adhesive tapes, non-stick packaging, release papers for hygiene products, baking parchment paper, release papers for indoor and outdoor adhesive posters, and coating on other substrates.

Active Ingredient Content (%)	100
Test Substrate	PE-coated paper	PET film
Silicone Coat Weight (g/m²)	1	1
Rapid Release Force (20min, gf/25mm)	5~8	3~5
Aged Release Force (70℃, 24h, gf/25mm)	10~15	5~8
Subsequent Adhesion Strength (70℃, 24h, %)	≥90	≥80

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℃.
