In modern industry and life, PC (polycarbonate) plastic is widely used in various products because of its excellent transparency, high strength and heat resistance products, such as electronic equipment, optical instruments, automotive parts and so on. Because PC plastic is sensitive to chemicals, especially the components in some sealants, it may cause stress cracking, surface corrosion and other problems. Therefore, it is crucial to choose a flexible sealant with no influence, no corrosion and no stress on PC plastics. Which flexible sealant is the most suitable one for PC plastic? This article will give you detailed answers.
 
 Understand the characteristics and sensitivity factors of PC plastics
Before selecting the suitable flexible sealant, it is necessary to understand the sensitive characteristics of PC plastic.
 PC plastic has many of these excellent properties, but its sensitivity to certain chemicals also limits its scope of application. Especially when selecting sealant, consider its compatibility with PC plastics.

Problems of sealant affecting PC plastic
Chemical corrosion: Some sealants contain solvents or chemical additives that may react with the PC plastic to cause surface corrosion or discoloration.
 Stress cracking: PC plastic is prone to stress cracking. This cracking is usually caused by the interaction of the components in the sealant with the stress-concentrated area on the PC plastic surface.
 Decomposition of volatile substances: some sealants released in the use process of volatile substances will decompose PC plastic, resulting in the mechanical strength of plastic greatly reduced, this impact is particularly obvious in the high temperature and high humidity environment.
 
 Which flexible sealant has no effect on the PC plastic?
 MS polymer sealant: MS polymer sealant ENIENT EG0510 series combines molecular chain expansion improvement on the basis of silicone, with good flexibility, adhesion and weather resistance, while almost no VOC volatilization. It is not corrosive to PC plastic, and contains no solvent, it is a very friendly sealant to PC plastic.

Use the case
Electronic equipment: MS polymer sealant is often used for sealing and bonding of electronic equipment to ensure the stability of electronic components in various environments.
 Automotive industry: MS polymer sealant is used in automotive manufacturing for headlights, automotive central control screen, various control connectors and other parts of the sealing, to provide lasting waterproof and dustproof effect.
 Marine engineering: MS polymer sealant is widely used in Marine monitoring equipment and Marine equipment, which can well withstand salt spray erosion and seawater immersion corrosion, and provide long-term protection for electronic equipment.
