LUA2010
LUA2010 soft-touch polyurethane clear lacquer
Two-pack polyurethane soft-touch topcoat: a matt, pleasant, soft velvety-feel finish. Cured with its dedicated hardener LNB010 (30 % by weight) and thinned with the slow thinner LZC8643. Applied by spray or curtain coater at 100–120 g/m².
- tactile topcoat on furniture fronts, panels, handles and cabinets
- over a pigmented PU finish or a clear PU sealer to give a velvet-touch feel

Mixing matrix
- LNB010Hardener% by weight: 30 %official% by volume: 30 %official
Always; this is the only listed hardener.
LNB010 is Milesi's dedicated soft-touch hardener, 65 ± 1 % solids. Fixed ratio — do not go short or long on it; the soft-touch feel and resistance depend on hitting the stoichiometry. Weigh it.
- LZC8643Thinner% by weight: 10–30 (typ. 20) %official% by volume: 10–30 %official
10–15 % for curtain coater and airmix; 20–30 % for conventional/HVLP and hot shops.
LZC8643 is Milesi's slow PU thinner (density 0.850 ± 0.01 kg/l); t-color.ru: 'for polyurethane and acrylic materials'. Milesi TDS: for gloss PU finishes (LHR, LDA) and all PU products, mainly in hot weather; slightly faster than LZC70, strong solvency. No other thinner is listed for LUA2010.
- S50Thinner% by weight: 10–30 (typ. 20) %recommended
Only as a stand-in when LZC8643 is unavailable, after a test panel; S80 is the closer evaporation match, S50 only at ≤22 °C.

- Coats
- 1 even full coat over a sanded base (2 light passes cross-hatched, wet-on-wet)recommended
- Flash-off
- 3–8 minrecommended
- Recoat
- Not intended to be recoated; if a defect needs fixing, rework the whole panel: scuff after full cure (≥24 h) and respray edge to edgerecommended
- Sanding between coats
- Base/sealer: P320–P400, de-dust thoroughly. Never sand or polish the LUA2010 film itselfrecommended

Curtain coating is officially allowed, 100–120 g/m². Flat or slightly profiled parts only.
Process and compatibility
- Substrate preparation
- Only over a prepared base: sanded PU sealer or a pigmented PU finish, fully de-dusted. Wood moisture 8–12 %. Never over bare wood.recommended
- Goes over (derived)
- LBA42,LBA521,LBA528,LKR6,KKR1recommended
- Sanding
- Sand the base P320–P400 before LUA2010; do not sand, polish or buff the soft-touch filmrecommended
- Temperature and humidity
- Apply and cure at 18–25 °C, RH 50–70 %; never below 15 °C. Above ~25 °C use the top of the LZC8643 range.recommended
- Don'ts
- don't change the LNB010 ratio (exactly 30 %)
- don't use other hardeners (LNB99, LNB16405 etc.)
- don't sand or polish the finished soft-touch film
- don't spot-repair — respray the whole panel
- don't apply over bare wood without a sealer
- don't spray above 75 % RH or below 15 °C
Storage
- Storage temperature
- +5…+25 °C, tightly closed; keep LNB010 sealed — it reacts with air moisturerecommended
- Hardener price
- 3 201 ₽/kg (LNB010, to order)dealer
Safety: Contains solvents and, in the LNB010 hardener, isocyanates. Spray only in a ventilated booth, with an A2P2 carbon respirator (air-fed is better), nitrile gloves and eye protection. Keep away from ignition sources.
