1. Features

ZS-GF-5299E is a low viscosity two-component addition cure silicone sealant, that can be cured at room temperature or heat cure, the higher the temperature, the faster the curing. This product does not produce any byproducts in the curing reaction, which can be applied for PC (poly-carbonate), PP, ABS, PVC and other surface of metal. Complied with the ROHS, REACH of EU directive.

2.The Typical Application

Encapsulating and protecting the power module, or other electronic components.

3. Instructions
•Preparing: Stir completely A and B in each container,
•Mixing:A and B should be fully mixed according to the weighting ratio. Add B to A. Stirring(stir the glue dedicated blade) and mixing. Note that: should be mixed thoroughly when mixing the wall rubber of container into the plastic material.
•De-airing: after mixing which should vacuum degassing for 1-3 minutes.
•Potting: The mixture should be poured into the product as soon as possible, in order to avoid thickening and resulting in poor fluidity.
•Curing: Heat curing or at room temperature curing. The higher the temperature, the quicker curing. The temperature is low, the curing time will be extended either. In winter, it will take a long time to cure, so s est that heating curing. It is cured for 15 minutes at 80 ° C ~ 100 ° C, about 12 hours at room temperature.

4. Storage
•1 year shelf life if stored below 25 ℃, when the product passed its expiration date, it should be confirmed without abnormal phenomenon, then that can be used.
•These products don't belong to dangerous goods, so they can be transported as normal chemicals. But be careful of leakage.

5. Note
•The mixture should be sealed and stored in a dry environment at room temperature, and should be used as soon as possible, to avoid wastage.
•The product don’t belong to dangerous goods, but avoid contacting skin and eyes.
•The product is non-toxic, has good physical inertia without stimulation and harm. The product does not contain flammable and explosive ingredients which will not cause fire or explosion without special requirement for transport.
•Stored for a period of time, the plastic may be layered. So please stir well before using, and can’t affect its performance.
•The following substances may hinder the curing or cause the phenomenon of not cure, so it is used after simple experiments, and need to clean the site of application if necessary.
A. incompletely cured condensation type silicone rubber.
B. amine (amine) curable epoxy resin.
