It is very important to choose suitable solvents, considering various factors, such as solubility, volatilization rate, safety, economy, source and storage stability. A good solvent must have good solubility, which can be judged by the solubility parameter and the hydrogen bond index. The drying rate of adhesives is directly related to the volatile rate of solvents, solvent-type adhesive solvents should be all volatile finally, the general hope that the adhesive dry quickly, this will choose the lower boiling point of the solvent. Most organic solvents are easy to burn, and when the solvent vapor reaches a certain concentration in the air, it explodes and must pay attention to the safety of the solvent. Most organic solvents have certain toxicity, endanger human health, pollute ecological environment, should arouse enough attention. Solvents in the solvent-type adhesives accounted for a large proportion, so you can not consider the cost of the problem, should be as far as possible with cheap and easy solvent.
