1. Since the solvent-based UV three-proof adhesive contains organic solvents, the main components of organic solvents include toluene, ethyl acetate, acetone, butanone, butyl ester, cyclohexane, n-hexane, methanol, hydrocarbon, ether, some of which are Chemical substances can cause harm to the human body and belong to high-risk products, which is contrary to the sustainable development strategy advocated by the state, and more and more such products will be banned from production and use;
2. When enterprises use solvent-based UV three-proof adhesives, in order to meet the national environmental protection requirements, they will add equipment for recycling organic solvents at the back end of manufacturing to prevent organic solvents from volatilizing into the air as much as possible. Therefore, back-end governance will increase the manufacturing process and cost of the enterprise;
3. Because the solid solution content of solvent-based UV three-proof adhesive is generally around 25-50%. Taking 25% solid content as an example, if an enterprise actually wants to use 100ml of UV three-proof paint, it must purchase 400ml of solvent-based UV three-proof glue (100/0.25). 100% solid solution, buy as much as you use), the actual purchase cost will increase a lot, resulting in an increase in manufacturing costs.
In summary, solvent-free UV three-proof adhesive will be the trend of use in the PCBA industry, and will inevitably replace the traditional solvent-based UV three-proof adhesive.
