Standard and method for classification of conformal coatings

Conformal coating, also known as circuit board conformal coating, three anti-glue, insulating paint, coating glue, coating glue, moisture-proof oil, generic film coating, coating coating, electronic coating materials, etc., is an English name of conformal coating.Conformal coating is a single component of room temperature curing, heating curing, UV curing transparent or translucent adhesives, with low viscosity, high transparency, excellent insulation performance, high and low temperature resistance, easy to use and so on.Conformation coating is mainly used in the assembly of all kinds of electronic circuit board surface coating, coating role, to provide protection for the circuit board, so that the circuit board to moisture-proof, anti-fouling, anti-salt spray, insulation and other protection, in order to improve product performance, stability, safety and service life of the role.It can also be used for shallow layer sealing and filling of electronic products.

Conformal coating is a very widely used auxiliary material for electronic, electrical and lighting products at present, with a very promising development prospect and a large market size and strong demand. The majority of customers very much recognize the three anti-paint products to bring higher added value and product performance to their end products.

So do you know the conformal coating?What are the types of three anti - paint?What is the classification standard of conformal coating?Our engineers will analyze and answer these questions.

1, according to the main material of the three anti paint to classify, can be divided into acrylic three anti paint, polyurethane three anti paint, silicone three anti paint, UV light curing and moisture double curing three anti paint.This kind of standard is the main classification standard of three anti - paint.

2. According to the use method, it can be divided into brush coating type three anti paint and spraying type three anti paint. This classification method is mainly based on the viscosity index of three anti paint, three anti paint with high viscosity is suitable for brush coating operation, three anti paint with low viscosity is suitable for spraying operation.

3, according to the temperature level, can be divided into high temperature resistant three anti paint and general three anti paint.The general temperature range of the high temperature resistant three paint is -60~200 degrees, high temperature resistant three paint is mainly silicone three paint.The temperature range of other types of three anti paint is generally about -40~130 degrees.According to the relevant requirements of the product to choose their own need for three anti paint.

4, according to the flame retardant standard can be divided into flame retardant three anti paint and non-flame retardant three anti paint.The flame retardant standard of three anti - flame retardant paint can reach UL94V0 standard.For some high-end, precision products and products with high temperature requirements, it is recommended to use the silicone flame retardant three-proof paint of Yaoneng Company.

5, according to whether it contains solvents to classify, can be divided into three solvent and three solvent containing paint, in general three solvent containing paint will be more, three solvent containing paint adhesion will be higher, but the smell is slightly bigger.

6. According to whether there is a fluorescent indicator in the composition of the three anti-paint, the three anti-paint can be divided into three anti-paint products with fluorescence and three anti-paint products without fluorescence.Three - proof paint containing fluorescent indicator, easy to detect the effect of three - proof paint after brushing.

7. According to the smell size of the three anti paint, it can be divided into three anti paint with smell and three anti paint with low smell.Electronic three anti paint absolutely odorless three anti paint is not, three anti paint is completely cured after no smell.In general, the smell of silicone three anti paint belongs to the low smell three anti paint.

8, according to the origin or brand to classify, three anti paint can also be divided into imported three anti paint and domestic three anti paint two categories.

The above is the introduction of the three anti paint related classification standards and methods by the engineers of Yao Neng Company. I hope it can be helpful for our customers in the selection and procurement of three anti paint, and also let us have a more comprehensive and in-depth understanding of the three anti paint, and deal with it in the process of use and production.Shenzhen Yaoneng Technology Co., Ltd. specializes in R & D and production of various electronic three paint, can provide customers with free sample test, product technical information to replace the import of three paint solution services.YaoNeng three anti paint strict selection of raw materials, stable quality, perfect service, and strive to provide our customers with more and better high value-added three anti paint products and service guidance.
