We have been cooperation with EM Chemicals for nearly one decade on printing thickeners, their thickener products whether pigment thickener or disperse thickener or reactive thickener are cost and performance wise with very stable quality. 

Based on their strict quality standards, they apply two-phase quality control procedures in both onsite workshop scale and center lab scale before the goods goes into their godown. I rest assured very much of their product quality. 

I have confident for their R&D capability. I asked them several times for different customized items, and every time they can response to me positively with satisfied result. They are so good a team I can rely on.
