Coating Material

(OP)
Hi, I'm looking for a material which can coat onto raw tinplates and this material must be able to:
1. resist 5 % acid content
2. have solvent resistance (i.e. MEK, MIBK, Ethyl Acetate)
If anyone has any knowledge or experience about this, I welcome your help on this. Thank you.

Too vague ...... "Raw tinplates" you say ???

Hi MJCronin, to be more specific, it is steel plate coated with a layer of pure tin on both sides. Tin coating is typically 2.8g/m2 while total thickness, including the steel, is typically around 0.25mm. This material is used to produce metal can containers for paint, oil, chemical and food industries. Thanks.

RE: Coating Material

Cans are coated after they are formed because the weld seams must be coated too.

RE: Coating Material

(OP)
Hi Compositepro, you are right to a certain extent. What we do is a 2 step process. First the tinplate in a big sheet form is coated and cured. After completion of the various manufacturing processes, when it gets finally formed into a can shape, a 2nd step of coating is applied to the weld seams. Typically the material for this 2nd step is different in the sense that it should cure be a fast air-cured type. So I would need the recommendation of 2 types of coating material to suit my purpose. Thanks.
