Ive been reading posts about the use of house paint, water based inks and solvent based inks recently and started to wonder what the real differences are between them. Ive come to the conclusion that there are a lot of similarities and common chemistry related to each. Common brake fluid DOT3 and DOT4 (propylene
glycol) is used as a retarder in water based inks and paint. Magnesium silicate (baby powder/Talc) is an ingredient in Nazdars 5500 poster ink and paper manufacturing. I suspect it helps the pigments stick to the paper better and may give it its flat property. I need to know how to reduce the odor of the solvent based inks short of adding a masking agent, which ive been told has to happen at the manufacturing level. I am also experimenting with some cross over chemistry from the Plastisol arena. I will keep you posted. I am about to test Unions Plasticharge additive in Nazdars 5500 series poster ink. I suspect, the 5500 series being a petroleum based product, will mix almost perfectly with the union product and give the ink a semi water soluble characteristic. I hope it doesnt blow up. I hope to achieve reduction in odor and increase in volume without sacrificing opacity. In theory I should then be able to retard the pot with propylene glycol. Being that Plasticharge is cheap and 5500 not so cheap this will be a winning situation if it works. Have any y'all tried any of this stuff? where y'all from?
