♦ Screen Cleaner N or H-002 thinner is recommended to clean the stencil.

Printing

♦ Avoid using finer (higher than T-225) mesh as it may cause clogging of the mesh.

Drying/Curing

♦ Tack-free drying time for treated PET is 15-20 minutes at room temperature (25°C ) with H-002 thinner and 20% dilution.
♦ Differences in substrate material, room temperature, amount of printed matter or size of printed area may affect the drying properties . Drying time should be determined before production printing. 30 minutes at 80°C is the standard drying time.
