Products Description

SC-9277 Low-VOC Conformal Coating Clear is a one component, low viscosity, silicone resin coating that is used to protect electronic components from stress and abrasions. It is an RTV elastoplastic, solvent based, low odor, cures at room temperature, and has reduced VOC. 1/5/15/15/20 kg Bladder.

Applications

* Circuit boards(PCBs)and assemblies

* Sensors

* MEMS and wafers

* LEDs

* Elastomer components

* Medical devices and components

* Motor components

Use:

Protective coating for rigid and flexible circuit boards. A one-part, self priming coating cures to flexible, transparent coating ideally suited for electronic printed wiring board applications.

Feature:

flexibility and high-temperature they are ideal for applications that require flexibility, such as when the PCB may bend or undergo thermal expansion. Silicone coatings also offer excellent moisture protection, making them a popular choice for outdoor or high humidity applications.

Advantages :

1. High-temperature resistance: Silicone coatings can withstand high temperatures, making them ideal for high-temperature
applications.
2. Flexibility: Silicone coatings are flexible, which means they can bend or undergo thermal expansion without cracking.
3. Moisture protection: Silicone coatings offer excellent moisture protection, making them ideal for outdoor or high humidity applications.
