We test the yellow sample and check its stability, and it turns out to be better too much. It is suitable for our highlighter ink. For this fluorescent ink dye, we consider purchasing a batch.

We use PTSA fluorescent tracer as a tracer in water systems together with our water treatment chemicals to monitor water balance changes. This sample is approved by our technician.

I sent an iquiry and receive soonest reply. Then we talked by WhatsApp phone pleasantly. Order is on procedure.

We are going to manufacture highlighters and require 5 colors to dye for the highlighter pen. After communication by phone and sample approval, we have a specific requirement about Solvent Green 7.

Due to lockdown, we just started to consume the last batch material. We will issue new order once we need it. In June, hope everthing is better and comes as formal.

We have a pleasant business with Kunshan Haite. For the first purchase order, we tested the samples after receving them and its result was measure up. This product can be used as a water treatment agent in our online cloud system, thus bring us more efficiency. It is the second time we have purchased from them. Expect to cooperate in long term.

We would like to use solvent green 7 to Continuse ink jet printers use in industry for printing expiry and manufacturing date. It can be soluble in ink.

The batch of solvent blue 36 I purchased from Kunshan Haite last month is really available for us. It doesn't influence the original chemical property of our product. It really has great heat resisitance. I expect order solvent dyes of other colors next for more requirements of customers.
