Referenced usage (can be adjusted according to actual production)

LT-730(30% emulsion)

☆ Padding:

Dosage: 10~50g/L

Process: one dip and one pad or two dips and two pads

☆ Dipping:

Dosage: 1~2%(o.w.f)           Liquor ratio: 1:15~20

Emulsifying & diluting method: add LT-730 first, and then add 1.5%~2.5% HAC of total silicone. When stirring evenly, add water slowly in batches and stirring till it’s emulsified. The emulsion will form translucent to transparent emulsion without particles.
