A. There are basically two types of catalyzed lacquer: Pre-catalyzed has the catalyst added at the factory, where with post-catalyzed, you add the catalyst at the time of use. Pre-cats are generally a little slower in dry time and cure because the catalyst is not as powerful, or "hot.".
SHER-WOOD® Catalyzed Lacquer (Precat) is a fast drying, high performance, catalyzed lacquer for the general wood finishing market. After catalyzation, it provides 6 months pot life as a precat lacquer.
Catalyzed lacquers consist of both pre- and post-catalyzed versions. Instead of curing by the evaporation of a solvent only, they also cure chemically. The catalyst can be added ahead of time (pre-catalyzed), or in your shop (post-catalyzed).
A look at Pre-cat Lacquer If you love lacquer but wish it was more durable, take a look at pre-catalyzed (pre-cat) lacquer. It retains the best qualities of traditional lacquer but provides a harder surface that better resists abrasion, thanks to a catalyst (think of two-part epoxy) that initiates a chemical reaction as the finish dries.
DuraCoat Pre-Catalyzed Lacquer are premium quality finishes for furniture, kitchen and bath cabinets and millwork shops. DuraCoat feature high solids, moisture resistance, good flexibility, mar resistance, and are much more durable than regular nitrocellulose lacquers.
