In today’s industrial manufacturing, sealants are widely used in the bonding application scenarios of electronic and electrical components. Washer sealing plays a particularly important role in this. It can prevent impurities such as external dust, moisture, corrosive media, etc. from invading the components, so as to avoid damage to the interior of machinery and equipment.

There are two forms of washer seals commonly used in the CIPG process, namely solid washers and liquid washers. Traditional solid washers generally include copper gaskets, stainless steel gaskets, asbestos gaskets, rubber gaskets, etc. The advantages of solid washers lie in their low cost and convenient operation. However, the disadvantages are that a large and diverse quantity needs to be stocked, which is not conducive to inventory management. Their shapes and sizes need to be customized in advance, resulting in poor flexibility. Moreover, automated production cannot be achieved.

Although solid washers currently occupy a large share of the market due to their low prices, with the development of industrial automation, the application of liquid sealing in the industrial field is constantly increasing. In the future, liquid sealing is bound to become the mainstream process in the sealing field. Compared with solid washer adhesives, liquid sealants are more flexible in operation. Because liquid sealants have fluidity, they can fill the depressions and gaps between the bonding surfaces. Currently, the commonly seen forms of liquid sealants are silicone sealants and UV adhesives. Since silicone sealants take 24 hours to cure while UV adhesives only need 20 minutes, more and more manufacturers are choosing liquid UV washer adhesives to complete the washer sealing in the CIPG process in order to improve production efficiency and commercial competitiveness. At present, liquid UV washer adhesive is an ideal sealing material and is widely used in the fields of lighting engineering, electrical and electronic industries, and automotive electrical engineering.

The MX-3608 UV sealing washer adhesive launched by Yantai Chemistry has received high praise in the industry. It has chemical resistance, low outgassing, and a fast curing speed. It is suitable for substrates such as nylon, most plastics (ABS, PVC, PC, PMMA), metals, etc. It is applied to speaker assembly, automotive casings, electrical appliance casings, HVAC (Heating, Ventilation and Air Conditioning) ducts, key electronic components and equipment, and has the properties of dust resistance, water resistance and airtightness.

1）It has a fast curing speed and can be cured within a few seconds, enabling the realization of a cured-in-place gasket.
