1. What are the normal working hours in the lab?

Lab time from 8.30 to 16.30

If there is a trial which runs a little bit longer, there is no charge, if it is several hours to get ready we charge the amount quoted for extra hours in our quote for lab trials

2. What would be the amount of material ( substrate and ink ) we would need?


Optimum the length of the substrate should be longer than the to be coated area and as a rule of thumb ad twice the machine length to it

Then it is possible to fill the whole unit with the original material and to leave it there as a prerunner for annother trial


Inks /coating fluids

The minimum amount the fluids needed is calculated:

Working width X coating length X coating thickness + dead volume in the coating system or the pump.


Important to take into consideration is, that sometimes there is more material needed for pretrials or several trials, so having more material helps. And stopping a trial in the middle of the day, because running of coating fluid makes noone happy.

3. Are we able to work with a limeted supply of the substrate, by using a prerunner material?

In principle yes and we do it

But there can be tension differences within the two different substrates, this can have an impact on your coating result.
You need a splicing which is sufficient to withstand temperature in the dryer and the tension in the process
You have to start and stop the coating exactly in the range of original material.
The coating system has to be lifted when the splice is comming in.

4. Which type of mixing capacity is available?

a) 20 l mixer with airwing or roundblade, sidescraper, vacuum option and the containers can be heated or cooled

b) Labmixer type dispermat for 3 liter volume with ?????

c) Lamixer for 2 liters with flügelrührer

d) Magnetic driven lab quirler

5. Which analysis tools are available?

a) mechanical ...

b) different scales from micron up to kg


d) radiometric absorption

e) Microscope

f) optical absorption (planed)

g) Viscosimeter

h) Scratch resistance


Beside the existing methods we also can rent the needed equipment for the trials.

6. Who is responsible for handling the disposables or is Coatema offering this?

The normal case is that the customer is shipping back his disposables. If this is not possible Coatema will ask a specific company to remoove the disposal and this normally quite expensive depending on the type of chemicals or substrates being used

7. Are we able to handle atex or hazardous to health materials

Yes we are. Most of the units are layed out after atex regulations. If there are additional actions needed it will be deiscussed with the customer. We always need the MSDS specification sheets and additional information before deciding this.
