I'm from Glasgow in Scotland and have been employed as a technical support rep for a large Italian wood finish manufacturer for the past 5 years. I often read these pages and am not ashamed to admit that some of the best advice I've given has been learned here.
However, I do sometimes struggle with the North American terminology which is used in the descriptions of certain coatings and would appreciate it if anyone would explain what the following terms mean:
Post cat (Is this the ureic, acid cured product like pre-cat but in 2k form, commonly known as A/C in Europe?)
From contributor F:
Post cat refers to post catalyzed lacquer, which is a urethane modified lacquer. Post means the catalyst is added after it is manufactured and prior to finishing. Conversion varnish, or a 2-pack coating, is a finicky high solids coating that, like post cat, must have a catalyst added just before spraying. I think C.A.B. refers to Cellulose Acetate Butyrate. But don't hold me to that.
In regard to the two component conversion varnish, this name allows the finishers and others to know that this is not the standard varnish, but the newer two component type coating.
2K systems may be catalytic systems, usually based on amino resins, or use reactive additives, such as the 2K polyurethanes, epoxies and acrylics.
