Conformal coating is a kind of protective polymer film, which can be applied on parts and keep the same appearance. The main purpose is to provide protection against part requirements. Each coating has unique chemical properties, which can be customized for specific protective performance. This means that a trade-off is often necessary when choosing the type of paint. We haven't found a super coating that can be used on all parts yet, although poly-p-xylene is getting closer We'll get there soon.


My biggest question is which type of paint should I use on the parts? Theoretically, the problem seems simple, but many layers need to be peeled before choosing the coating type. Before you take this path, you should ask yourself some initial questions:


1. What do I want to achieve with this coating?


One kind. Dielectric properties


B. Chemical resistance


C. Water resistance


D. Prevent dust or debris


E. lubrication


F. Barrier protection


G. Anti vibration


H. Wear resistance


2. Do I need to meet some requirements of the coating I choose?


A. Military specifications


B. UL authentication


C. Six level certification


D. RoHS compliant


E. AR70 / AFR80 / Navinst 3400.2






3. How long do I need my parts?


A. Precautions for curing time


B. Thickness requirement


C. How to paint


4. How big are my parts?


A. If I choose poly-p-xylene, is it suitable for coating room?


B. Do I need special clamps to paint the boards?


C. How much coating is required to achieve the required thickness?


D. Will the cost be affected?
