Glue factory shares classification standards for three proof paint
Conformal coatings, also known as circuit board conformal coatings, protective gels, insulation paints, coating adhesives, moisture-proof paints, electronic coating materials, etc., are referred to in English as conformal coating. Conformal coatings are a type of single-component adhesive that cures at room temperature, with heat, or under UV light, appearing either transparent or semi-transparent. They feature low viscosity, high transparency, excellent insulating properties, resistance to extreme temperatures, and ease of use. Conformal coatings are primarily used to coat and cover the surfaces of completed electronic circuit boards, providing protection against moisture, dirt, salt spray, vibration, and insulation, thereby enhancing product performance, stability, safety, and lifespan. They can also be used for shallow potting and filling in electronic and electrical products.
Conformal coatings are widely utilized in the electronics and lighting industries, with significant growth prospects and a large market demand. Customers recognize that these coatings bring higher added value and improved performance to their end products.
So, what do you know about conformal coatings? What types are there, and what are the classification standards? Engineers from the glue factory will analyze and answer these questions.
Organic Silicon Three proof Paint
1. Based on the main materials, conformal coatings can be classified into acrylic conformal coatings, polyurethane conformal coatings, silicone conformal coatings, UV-cured conformal coatings, and dual-cure conformal coatings. This standard serves as a primary classification criterion.
2. According to application methods, conformal coatings can be divided into brushable and sprayable types. This classification is mainly based on viscosity, with high-viscosity coatings being suitable for brushing and low-viscosity coatings ideal for spraying.
3. Temperature resistance can classify conformal coatings into high-temperature and standard types. High-temperature conformal coatings generally withstand temperatures from -60 to 200 degrees Celsius, primarily represented by silicone conformal coatings. Other types usually range from -40 to about 130 degrees Celsius. Customers should choose conformal coatings based on their specific product requirements.
4. In terms of flame retardance, they can be categorized into flame-retardant and non-flame-retardant conformal coatings, with the former meeting UL94V0 standards. For high-end, precision products requiring high-temperature resistance, it is recommended to use the silicone flame-retardant conformal coatings from the glue company.
5. Based on solvent content, these coatings can be classified into solvent-based and solvent-free types. Generally, solvent-based coatings are more common, offering higher adhesion but with a slightly stronger odor.
6. Conformal coatings can also be classified based on the presence of fluorescent indicators, into fluorescent and non-fluorescent types. Coatings with fluorescent indicators facilitate the inspection of coating effects after application.
7. Regarding odor, they can be categorized into fragrant and low-odor types. Truly odorless conformal coatings do not exist; however, any fully cured coating should be odorless. Typically, silicone conformal coatings have a lower odor profile.
8. Finally, by origin or brand, conformal coatings can be divided into imported and domestically produced coatings.
