LGA2AA44
LGA2AA44 PU lacquer, 25 gloss (matt)
Two-pack clear polyurethane topcoat, matt (25 gloss). Per the maker: excellent scratch resistance to EN 15186, good flow-out and film hardness; certified to 'EN71/1' (as printed — for toy coatings it's usually EN 71-3, migration of elements, that matters). Cured 2:1 with LNB20, LNB6AA0 or LNB77 (50 % by weight and by volume), thinned 20–40 % with S50/S80. Spray applied at 130–150 g/m².
- Clear matt (25 gloss) topcoat for furniture, fronts, doors and worktops
- Surfaces that take scratching (EN 15186 scratch resistance)
- Children's furniture and items needing EN 71 certification

Mixing matrix
- LNB20Hardener% by weight: 50 %official% by volume: 50 %official
Default choice. Fixed ratio — 2 parts lacquer to 1 part hardener, same by weight and by volume.
Don't cut or overdose the hardener 'for speed' or 'for hardness' — it ruins the crosslink. The hardener is moisture-sensitive: close the tin straight away.
- LNB6AA0Hardener% by weight: 50 %official% by volume: 50 %official
Alternative hardener officially approved for the LGA2AA series. Technocolor doesn't publish how it differs from LNB20 (speed, yellowing).
LNB6AA0 isn't listed at t-colormarket.ru — order through Technocolor. No data on it anywhere.
- LNB77Hardener% by weight: 50 %official% by volume: 50 %official
Third officially approved hardener. LNB77 is a common Milesi hardener for matt PU lacquers (also officially approved for LGA21/LGA210/LGA22) and is stocked by the dealer.
Same 2:1 ratio. Unlike LGA2AA47 (5 gloss), LNB77 is allowed on LGA2AA44.
- S50Thinner% by weight: 20–40 (typ. 25) %official% by volume: 20–40 %official
Universal, normal-evaporation thinner — the default; vertical work, 18–25 °C.
Doesn't change cure time. (workshop)
- S80Thinner% by weight: 20–40 %official% by volume: 20–40 %official
Slow — above ~25 °C, large panels, flat work; keeps a wet edge so the matt comes out even without patchiness.
More dust pick-up and more sag risk on verticals; doesn't change cure time. (workshop)

Application
Conventional spray
- Consumption
- 130–150 g/m² per coatofficial
Matt lacquers: stir right to the bottom (the matting agent settles), lay it on evenly in one wet pass with 50 % overlap; too heavy raises the sheen and goes milky, too light gives a patchy matt.
HVLP
- Consumption
- 130–150 g/m² per coatofficial
15–20 cm gun distance, 50–75 % overlap, fan fully open (as in the owner's notes for ATL50 G).
Airmix (air-assisted airless)
- Consumption
- 130–150 g/m² per coatofficial
Electrostatic
Electrostatic isn't listed for LGA2AA44. Untested.
Process and compatibility
- Substrate preparation
- Over a sanded (P320–P400), de-dusted PU sealer; timber at 8–10 % moisture.recommended
- Temperature and humidity
- 18–25 °C, 50–70 % RH; above 25 °C use S80recommended
- Don'ts
- Don't change the 2:1 hardener ratio
- Don't sand or polish the final matt coat — you'll get shiny burnish patches
- Don't lay it on too heavy (>150 g/m²) — sheen goes up and the film clouds
- Don't top up spent mix with fresh
- Don't spray above ~75 % RH — the isocyanate reacts with moisture (bubbles, blushing)
- Don't put it straight onto bare wood without a PU sealer
Storage
Safety: No safety data published. Solvent-borne 2K PU with an isocyanate hardener: flammable; spray in a ventilated booth wearing an A2P2 (or air-fed) respirator, gloves and eye protection.
