Made for electrostatic (incl. air-assisted) and ordinary spraying of chairs, turnings, frames and solid-wood items. Topcoat over LBA PU sealers (LBA528/LBA523).
- Chairs, stools, cots — open-frame work
- Turnings and table legs
- Frames and profiles
- Assembled furniture and solid-wood items (beech etc.)

Standard option per the Technocolor page — pick one of the three hardeners.
LNB42 gives better build (TDS), for ordinary spray; LNB77 is the hardener for PU primers and matt lacquers, 25 ± 1 % solids (t-colormarket), ordinary spray; LNB5 is for electrostatic discs/bells and where better wetting is needed (UA dealer).

UA dealer: LNB42 for ordinary spraying.
- LNB5 / LNB05Hardener% by weight: 50 %dealer
Electrostatic discs and bells, extra wetting.
- LNB36Hardener% by weight: 50 %dealer
Faster drying and better vertical hold while keeping good wetting.
Not on the Technocolor page.
- LNB06Hardener% by weight: 50 %dealer
Better build and softer feel.
The BG schedule calls LNB06 a higher-solids hardener (used with the LBA528 sealer). No confirmed Technocolor equivalent; not listed on the Technocolor LGA532 page.
- LNBHardener% by volume: 50 %dealer
Electrostatic schedule from Milesi's Bulgarian distributor (unspecified LNB hardener).
- % by weight: 10–30 (typ. 20) %official% by volume: 10–30 %official
Standard range per the Technocolor page.
S50 = medium evaporation, the default, good on verticals. S70/S80 = slow (catalog: for dead-matt and high-gloss PU/acrylics) — use above ~25 °C or on big flats; more dust pick-up and sag risk. Neither changes cure time. 10 % = more build, 30 % = thinner, smoother film.
- LZC1026Thinner% by weight: 10–30 %datasheet
Per Milesi TDS (spray).
LZC1026 is Milesi's universal medium thinner. Technocolor lists S50/S70/S80 instead.
- LZC13Thinner% by volume: 25–30 %dealer
Electrostatic spraying.
LZC13 is Milesi's electrostatic thinner (BG schedule). The worked example is 0.35 l per 1 l lacquer — 35 % on part A or ~23 % on A+B; the schedule text says 25–30 %.

Stir part A well before mixing (thixotropy + matting agent). Thixotropic lacquer levels worse on flat horizontals — orange peel is possible; for tops and panels pick a non-thixotropic lacquer.

Process and compatibility

- Sanding
- sealer P280–P320 after 3 h, topcoat within 4 hdealer
- Temperature and humidity
- 20 °C, 70 % RH reference; store 18–25 °Cdatasheet
- Don'ts
- Don't use the mix past pot life (2–3 h) or thin it once it thickens
- Don't topcoat a sealer that's less than 2 h old — satin finishes wet out worse on fresh sealer (TDS)
- Don't wait more than 4 h after sanding the sealer (BG)
- Don't sand or polish the final 45-gloss coat
- Avoid big flat horizontals — thixotropic lacquer levels poorly
- Keep hardener tins closed — moisture-sensitive

Safety: Solvent-borne; hardener contains isocyanates. Spray in an extracted booth with an A2 respirator (air-fed preferred), nitrile gloves and eye protection. Flammable. Ground all electrostatic equipment and parts.
