LGA533
LGA533 thixotropic 2K polyurethane lacquer, 30 gloss
Two-pack clear polyurethane topcoat, 30 gloss, from Milesi's LGA531–536 series, built for electrostatic and ordinary spray. Thixotropic so it hangs on verticals without runs, dries fast and leaves a silky, nice-to-touch film. Made for chairs, turnings, carvings and frames — parts you spray all round in one go.
- chairs, stools, children's furniture
- turnings: spindles, legs, handrails
- carved and relief parts, frames, overlays
- electrostatic finishing on hangers or conveyors

Always, fixed at 50 %. Per Milesi: LNB5 (= LNB05) for electrostatic spray (bells/discs) or when you need better wetting; LNB42 and LNB77 for ordinary air spray; LNB42 gives more fill.
LNB77 is 25 ± 1 % solids (t-colormarket). Technocolor's 'LNB5' is Milesi LNB05 (Milesi dealer writes 'LNB 5/05', the Bulgarian distributor 'LNB05'; Technocolor likewise writes LNB6 for LNB06 on LBA528). Hardeners hate moisture — lid straight back on.
- LNB500Hardener% by weight: 50 %datasheet
Milesi TDS standard (3 h pot life).
Not listed under this code in Technocolor's range. The newer Milesi TDS also mentions LNB36 (faster drying, better hang) and LNB06 (more fill and softness), both at 50 %; neither is listed by Technocolor.
- LNB42Hardener% by weight: 50 %datasheet
For better filling power (Milesi TDS: 'use LNB 42 (50 %) instead of LNB 500').
- LNB (series)Hardener% by volume: 50 %dealer
Electrostatic schedule from Milesi's Bulgarian distributor — 'a hardener from the LNB series', no specific code.
- % by weight: 10–30 (typ. 20) %official% by volume: 10–30 %official
S50 — universal, medium evaporation: normal 18–24 °C shop. S70 — slow (medium solvency): above ~25 °C, big hanger loads, long passes round a chair. S80 — slow with good solvency: same, plus when the film goes dry/sandy on edges and won't knit.
Thinner choice doesn't change cure time. Slow thinner on a thixotropic lacquer on verticals still raises sag risk if you flood it.
- LZC1026Thinner% by weight: 10–30 %datasheet
Milesi's own thinner per the TDS; Technocolor substitutes S50.
- LZC13Thinner% by volume: 25–35 %dealer
Electrostatic spray: Milesi's dedicated electrostatic thinner. Text says 25–30 %, the worked example is 35 %.
Electrostatic thinners are tuned for conductivity; Technocolor's S50/S70/S80 aren't sold as electrostatic grades — check wrap and charge on a test part before running a batch.

Process and compatibility
- Substrate preparation
- Solid wood (beech etc.) or MDF: sand, stain if wanted with CFT water stain (dipped), then an electrostatic PU sealer LBA523 / LBA528, dry, sand P280–P320 after 3 h, topcoat within 4 h of sanding.datasheet
- Sanding
- Sealer P280–P320 after 3 h; between topcoats P400–P600 / grey pad; never sand or polish the final 30-gloss coat.dealer
- Temperature and humidity
- Data measured at 20 °C, 70 % RH (TDS). Work at normal shop temperature, ~18–25 °C material and room.datasheet
- Don'ts
- Don't topcoat a sealer that's less than ~2 h old — PU topcoats wet poorly over fresh sealer (Milesi TDS).
- Don't use it on big flat horizontals (tabletops, doors) — thixotropic lacquer flows out poorly: orange peel, starved pores.
- Don't brush or roll it — fast two-pack thixotropic lacquer.
- Don't eyeball the hardener — 50 %, every time.
- Don't leave the hardener can open — moisture kills the isocyanate.
- Don't sand or polish the final 30-gloss coat.
Storage

Safety: Two-pack PU: the hardener contains isocyanates and the solvents are flammable. Spray in an extracted booth, wear an A2P2 respirator (air-fed is better) and nitrile gloves. With electrostatics earth everything and avoid sparking. Don't seal leftover mixed material tight — it gives off CO₂.
