product classification:Acrylic acid proof paint
product model:8516
8516 Moistureproof protective paint (Confomer Coating)
1. Introduction to product
As a transparent protective paint, this kind 8516 paint can be used for various PCB to form protective film so that the electric leakage and short circuit can be avoided effectively. In addition, the transparent acrylic acid film can protective the PCB and alike from the corrosion of weak acid、alkali、alcohol as well as dampness, also this paint has the features like heat resistance so it is available to add tin onto the PCB protected by this kind of paint.
2.Application scope
Due the features like waterproof and dampproof, the insulation performance can be improved effectively to isolate the wires、cables as well as the contact between the joint of wire、cable 、screw joint 、switch box and air. So when used for TV, the corona discharge of ignition coil and other components can be avoided effectively, also it is available to be used for the protection of map、graphic、document、drawing and alike, in addition, this kind product can protect the HF antenna、TV antenna and other antenna from the corrosion effectively; when used for marine communication equipment and electrical equipment, the salt fog corrosion can be avoided effectively.
3. Features and advantages
Due to dampproof and salt-fog protection features, the useful life of equipment can be extended effectively with a long time protection to electric apparatus、equipments and parts and alike. In addition, due to the heat resistance feature, only when the temp is up to 150 oC, the protective film begins softening, and becomes glutinous state, but it does not drop, also the PCB is allowable to be added with tin. The construction methods include brush、spray、dipping and others.
