覆形材料是一种对PCB的防护漆，是一种专为电子线路板及元器件设计的特殊涂料，涂覆固化后形成保护膜，能实现防潮、防尘、防霉等多种防护功能。

industrial electronics

conformal coating can form a dense protective layer on the surface of the circuit board of industrial electronic equipment, effectively isolate moisture, salt spray and corrosive gases, inhibit electrochemical corrosion of metal substrates, and reduce the risk of surface leakage. Its flexible resin matrix can also cushion mechanical stress, absorb vibration impact energy, reduce solder joint cracking and circuit board deformation, and ensure the stable operation of equipment under extreme temperature and humidity.

consumer electronics

face the needs of miniaturization and integration of consumer electronics, conformal coatings build a multi-functional system with mechanical protection, chemical isolation and electrical insulation by controlling the coating thickness and curing process, which can resist sweat, cosmetics and dust pollution, and reduce the risk of circuit short circuit. Its coating process is suitable for high-density circuit boards, special-shaped shells and small gaps, which can achieve uniform coverage of three-dimensional structures, taking into account production efficiency and yield rate.

automotive electronic systems

automotive electronic systems face challenges such as high temperature, high humidity, high vibration and chemical corrosion, conformal coatings can build a protective layer that is resistant to temperature change, oil stains and vibrations, reduce coating cracking caused by thermal stress cycles, and ensure the stability of components in a wide temperature range. In addition, conformal paints made of composite conductive fillers or electromagnetic shielding materials can form protective and shielding composite coatings to reduce electromagnetic crosstalk and improve signal transmission reliability.

Aerospace Equipment

aerospace equipment needs to operate in extreme environments such as vacuum, radiation and high and low temperature alternation, and conformal coatings isolate high-energy particles, ultraviolet radiation and atomic oxygen flow by building a protective layer with low volatility, radiation resistance and anti-atomic oxygen erosion, and extend the life of equipment in orbit. Its coating process is suitable for tiny pads, precision connectors and complex three-dimensional structures, which can strictly control the coating thickness and curing uniformity to avoid deterioration of electrical properties.

new energy equipment

new energy equipment needs to have weather resistance, moisture and heat resistance and chemical corrosion resistance, conformal coatings are widely used in photovoltaic inverters, energy storage battery management systems and wind power converters and other fields through material modification and process innovation. Some conformal coatings introduce intelligent materials such as self-healing microcapsules and temperature-sensitive polymers to build a dynamic protective layer to achieve active protection, and can also optimize the thermal conductivity and flame retardant characteristics of the coating to inhibit the risk of thermal runaway.

medical device

conformal coatings can protect the electronic equipment in medical equipment from external chemicals and special use environments, ensuring its continuous and stable operation, such as various medical and test instruments.
