What is catalyzed varnish?
A catalyzed conversion varnish is a fast-drying finish that comes in two parts: the finish and an acid catalyst (hardener) that is added to the finish just before spraying.
What is Post catalyzed varnish?
Conversion varnish, also called catalyzed conversion varnish or catalyzed varnish, is a lacquer which consists of a high-end solid two-part post-catalyzed application process. Conversion varnish is chemically cured and fast-drying, and consists of 40-60% solids.
What is pre catalyzed varnish?
Precatalyzed (pre-cat) Lacquers are blends of nitrocellulose resin, plasticizers and thermosetting resins dissolved in solvent. The reaction of these thermosetting resins is accelerated by addition of a weak catalyst by the coating manufacturer; the weak catalyst ensures a longer shelf life (usually 90 – 365 days).
How do you mix conversion varnish?
Mix 1 Part Catalyst to 10 Parts Conversion Varnish, Measured by Weight or Volume.
What is a catalyzed lacquer finish?
A catalyzed lacquer is a coating that dries by evaporation, acting very much like a straight lacquer (defined above with no chemical curing or crosslinking) and then cures by the reaction initiated by the catalyst.
What is the difference between lacquer and conversion varnish?
Comparing Conversion Varnish vs Lacquer. A lacquer is a single-component, pre-catalyzed, nitro-celluloid finishthat has 12-18% solids by volume. It is air-cured. A conversion varnish is a high-end solids, two-part post-catalyzed lacquer, which means a hardener must be mixed with this product for the application.
How long does catalyzed lacquer last?
SHER-WOOD® Catalyzed Lacquer (Precat) is a fast drying, high performance, conversion lacquer for the general wood finishing market. After catalyzation, it provides 6 months pot life as a precat lacquer.
Is conversion varnish oil based?
It is less toxic, has a smaller environmental impact and is safer to use in terms of fire and explosion. In many ways, water-based varnish shares the characteristics and handling of oil-based varnish. Conversion varnish is a catalyzed, alkyd-based compound.
Which is better varnish or polyurethane?
While polyurethane is water- or oil-based plastic resin, varnish is older and made from resins, oils, and solvents. Because of the higher ratio of solids, varnish is less susceptible to ultraviolet light damage. This protection makes varnish an excellent choice for projects such as outside decks and exterior furniture.
What is a catalyst finish?
A Quality Finish For Solid Wood Furniture: What Is Catalyzed Conversion Varnish? Catalyzed conversion varnish basically consists of two parts, the finish liquid and a hardener(called the catalyst) that gets mixed in right before it’s applied. It’s fast drying and is considered the golden standard for varnish.
