Siemtcoat® SF363

Siemtcoat® SF363
A Solventless Silicone Release Coating for Cost-Effective Excellence

Siemtcoat® SF363 is a solventless silicone release coating, known for its fast curingproperties, cost-effectiveness, and remarkable versatility across a range of substrates, including Glassine, PEK, CCK, etc. This high-performance coating is the ideal solution for manufacturers in search of reliable, efficient, and budget-friendly coating options. With Siemtcoat® SF363, you can achieve superior release performance while optimizing your production costs.

General

A three-component solventless system, specially designed for Glassine, PEK, CCK, ect. substrate coatings.
We recommend the following formulas:

• Siemtcoat® SF363-Base Polymer
• Siemtcoat® 8982-Crosslinker
• Siemtcoat® 5000-Catalyst

Application

Siemtcoat® SF363 is specially designed for Glassine, PEK, CCK, ect. substrate coatings. The dosage of each component should be adjusted based on specific process conditions and application requirements. After thoroughly mixing the components, apply the coating to the substrate surface for curing to achieve the target release profile. 

Advantage

• Low Migration
• Fast cure
• Low platinum and Cost effective
• Suitable for various adhesive systems

Properties

Processing

When applying Siemtcoat® SF363 into the Siemtcoat system, please strictly adhere to the following mixing procedure:

1. Weigh the base polymer Siemtcoat® SF363---XX parts.
2. Weighthe crosslinker Siemtcoat® 8982---XX 
3. Add the weighed crosslinker and thoroughly mix to ensure complete dispersion.
4. Weigh the catalyst Siemtcoat® 5000---XX parts, and add it during mixing. (Attention: Do not mix the crosslinker and catalyst directly, as a dramatic reaction will occur.)
5. Continue mixing until the catalyst achieves a uniform distribution throughout the mixture.

Bath life

The bath life of all Siemtcoat systems depends on formulation, equipment, mixing process, temperature, and environment. Siemtcoat® SF363 only does not alter its original bath life, typically lasting about 5 hours at 40℃.

Release force

Release force performance depends on multiple factors.

We measure release force using different substrates and adhesives to define its characteristics. While the standard release force measure could use standard tape to measure.

Typical release force performance:

Tesa Tape 7475 (23℃): 5 to 15 g/25mm (0.3 m/min peeling speed)

Curing

The curing results of the Siemtcoat system depend primarily on the formulation, substrate quality, curing temperature, and oven efficiency. We obtained the following results:

(Curing time is defined as the minimum curing duration without any smear, rub-off, or migration of the release coating layer.)

Package

Shelf-life

Siemtcoat® SF363 should be stored in a closed container at -20°C to +30°C temperature.

Siemtcoat standard shelf-life is 24 months.

Safety
