Siemtcoat® SF300H

Release Coating modifier
Siemtcoat® SF300H

General
- A three components solventless system special design for Glassine PEK, CCK ect.substrate Coating.
- Siemtcoat® SF300H (Main polymer）
- Siemtcoat® 8982（Crosslinker）
- Siemtcoat® 5000 (Catalyst)

Application
- The SF300H is special design for Glassine PEK,CCK ect. substrate coating.
- The dosage of different component should be adjusted base on different process
- Condition and application. After mixed components even, the coating on the substrate
- Surface to curing and achieved the target release profile.

Advantage
- Long bath life and good anchorage performance with additive add in
- Low silicon migration
- Suit for different type adhesive system

Appearance	Clear liquid
Active（%）	100

Density (g/cm³)	0.97

Processing

- When applicate SF300H into Siemtcoat system, please following bellowing ratio and mixing process:

    . 1- Weight the main polymer SF300H-------------- 100p

    . 2- Weight the crosslinker

- Siemtcoat® 8982--------------------- 2.2-2.5 p

    . 3- Mix the crosslinker and make sure it was dispenser well.

    . 4- Weight the catalyst Siemtcoat® 5000 and add in during mixing Siemtcoat® 5000------------------------ 1.0-1.3 p

(Attention: do not mix the crosslinker and catalyst directly as dramatic reaction would happen.)

    . 5- Mix until the catalyst even.

Bath life

- All Siemtcoat system bath life is relative to the formulation, equipment, mixing

- Process, temperature and environment. SF300H additive would not change the

- Siemtcoat original bath life (Normally about 5 hours at 40℃)

Release force

- Release force performance is relative for many factors.

- We measure the release force with different substrate and adhesive to define the

- Release force performance. 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 （0.3m/min peeling speed）

Curing

- Siemtcoat system curing results is relative the formulation, quality for substrate,

- Curing temperature and oven efficiency. We acquired the following results :

(Curing time define as the minimum curing time without smear, no rub-off and migration of release coating layer)

Package

Shelf-life

- Siemtcoat SF300H should be storage in a closed container at -20°C to +30°C temperature.

- Siemtcoat standard shelf-life is 24 months。The expired day is marked on label for each drum.

Safety

- Please referents Siemtcoat® SF300H，8982，5000 MSDS.
