PPS50277
PPS50277 white thixotropic high-solids PU primer
Two-pack white high-solids polyurethane primer with the strongest thixotropy in the range. Won't run off edges, hides and fills grain well, builds hardness fast. Good for intricate carved work. Cured with PC20 at 30 % by weight (alternative PC72 at 20 %: more flexible, slower drying), thinned with S50.
- vertical surfaces
- cots and chairs in various woods
- MDF
- assembled pieces
- intricate carved work
- base under coloured enamels
- base for the 'Chrome' and 'Pearl' special effects

Mixing matrix
- PC20Hardener% by weight: 30 %dealer% by volume: 45 %dealer
standard hardener
Fixed ratio. Don't confuse it with PPS50 (that one is 50 %).
- PC21Hardener% by weight: 30 %workshop
alternative to PC20 per the owner's datasheet
PC21 appears only in the owner's datasheet (PC20/PC21 30 %); not on the sites or in the catalogue.
- PC72Hardener% by weight: 20 %dealer
when a more flexible film is needed
Dealer prints 'С72'; the catalogue chart shows it as PC72 (aromatic, slow/flexible). More flexible film, longer drying.
- S50Thinner% by weight: 10–20 (typ. 15) %dealer% by volume: 15–35 %dealer
default; go to 20 % if you are stuck with a 1.5 mm gun
Doesn't change cure time.
