What is the function of CS-867 silicone three proof paint and is it toxic?
CS-867 organic silicon three proof paint material is a thin layer material applied to the surface of components or circuits using immersion coating, spray coating, brush coating and other processes to extend their lifespan and protect them from harsh environments and mechanical damage.
CS-867 Organic Silicon Three proof Paint Composition
Acrylic products: Acrylic three proof paint has strong flexibility and can provide comprehensive protection. Due to its single component system, it has good adhesion, simple operation, low requirements for equipment and conditions, convenient construction, high transparency, high brightness, and short operation cycle, making it easy to use and clear. Some acrylic products meet military standards, they dry quickly without drying, and can be removed with matching organic solvents. Therefore, this type of circuit board three proof paint is one of the most widely used and effective products on the market.
CS-867 Organic Silicon Three proof Paint Function
Moisture is the most common and destructive factor for PCB circuit boards. Excessive moisture can significantly reduce the insulation resistance between conductors, accelerate high-speed decomposition, lower Q values, and corrode conductors. We often see copper patina on the metal parts of PCB circuit boards, which is caused by the chemical reaction between uncoated copper metal, water vapor, and oxygen.
Coating three proof paint on printed circuit boards, LED surface mount displays, and components can reduce or eliminate electronic performance degradation when they may be affected by adverse environmental factors. If this coating can maintain its function for a satisfactory period of time, such as exceeding the product's service life, it can be considered as achieving its coating purpose.
Is CS-867 silicone three proof paint toxic
The toxicity of CS-867 silicone three proof paint depends on the type of diluent and solvent used. If toluene or xylene is used as a diluent for the three proof paint, this chemical is harmful to the human body. If lipids, alcohols, and other substances are used, the harm is relatively small. Xylene has moderate toxicity and irritates the eyes and upper respiratory tract. At high concentrations, it has an anesthetic effect on the central system.
Although there are many environmentally friendly three proof paints on the market now, it is still necessary for us to take protective measures and wear gas masks when using them in practice.
