What diluents can be used to dilute screen printing hot melt adhesive?
Screen printing hot melt adhesive is usually diluted with the following diluents:
Ethyl acetate: commonly used and effective, can effectively reduce viscosity.
Acetone: highly volatile, suitable for quick drying occasions.
Toluene: strong dissolving power, but need to pay attention to its toxicity.
Xylene: good dissolving effect, also need to pay attention to toxicity.
Cyclohexanone: strong dissolving power, suitable for high viscosity glue.
Methyl ethyl ketone (MEK): highly volatile, suitable for quick drying.
Precautions:
Toxicity: Solvents such as toluene and xylene are toxic, and ventilation and protective equipment are required when using.
Volatility: Acetone, butanone and other solvents are highly volatile and need to be fireproof and explosion-proof.
Proportion control: Too much diluent will affect the performance of the glue, and it needs to be added in appropriate amounts.
Testing: It is recommended to test on a small scale first to ensure that the effect meets the requirements.
The selection of the appropriate diluent depends on the specific application and glue type.
