How to Thin Spray Applied High Solids Coatings

摘要

There is a good deal of speculation today about the development of paints especially chemical agent resistant coatings (CARC), that do not need thin-ners. I have tried this and the finish is a dry, dusty coat that is easily rubbed off. Have you any experience with products, other than water-reducible paints, that can be sprayed out of the can? We used a well known HVLP gun with about 35 pounds of pot pressure. If you know of paints being sprayed without thinner, what equipment was used? I'm sure I have seen high solids coatings sprayed out of the can without thinning. But since I'm not the one who mixes the paint I can't tell you for sure. I do know for sure that coatings at 3.5 lb./gal. can be spray applied using HVLP guns. If the paint you are using is at 3.5 lb./gal. and you are not able to atomize it, there is a strong possibility the fluid pressure at the gun is too high and you don't have sufficient air to atomize it.
