standard finish
LNB99 is the non-yellowing hardener for acrylics; safe on chemically bleached timber.

when extra chemical resistance is needed (kitchens, bathrooms)
Dries noticeably faster, but the sheen rises by about 5 GU (≈ 20 instead of 15). Don't mix 10 % and 20 % batches on one job — the sheen won't match.

the only listed thinner — for spray and curtain coating
LZC8643 is a slow PU thinner for PU and acrylic materials. Slow solvent gives a good lay-down on a matt lacquer but more dust pick-up and sag risk on verticals — stay nearer 20 % there.

UV-absorber additive; listed in the 460–468 series note.

- Dry film
- 15–20 µmrecommended
- Coats
- 1–2 topcoats over a sanded sealerrecommended
- Flash-off
- 10–15 minrecommended
- Recoat
- after ~3–4 h; denib (P320–P400) before each further coatrecommended
- Sanding between coats
- P320–P400 (denib); never sand or polish the final matt coatrecommended
- Gun distance
- 15–20 cmrecommended
Fan wide open, 50–75 % overlap, one even wet pass — don't dust extra onto a drying film or the sheen goes blotchy.
Conventional spray

- 1.4–1.6 (typ. 1.5) mmrecommended
- Pressure · air
- 3–4 barrecommended
- Spray viscosity
- 16–20 s DIN4/VZ-4recommended
- Consumption
- 100–120 g/m²official
Conventional spray transfers only up to ~40 %, so real usage is higher.

Curtain coater

- 120–140 g/m²official
- Wet film
- 125–150 µmrecommended
Curtain coating suits flat and lightly profiled parts (doors, sides, shelves). Viscosity, belt speed and head gap are set on the line — Technocolor doesn't publish them.
Electrostatic
Possible with any spray system (methods page); for a solvent acrylic set it up like airmix/conventional.
Process and compatibility
- Goes over
- polyester primers (well sanded) / LBA1 (PU primer, catalysed 50–70 % LNB17) / LJA99 (fully cured)
- Substrate preparation
- Sand primer/sealer to P320–P400, dust off, apply within the primer's recoat windowrecommended
- Sanding
- denib between coats P320–P400; final coat left as sprayedrecommended
- Temperature and humidity
- 18–25 °C, RH 50–70 %, material and parts at room temperaturerecommended
- Don'ts
- don't use any hardener other than LNB99
- don't exceed 20 % hardener
- don't mix batches with different hardener % on one job — the sheen will differ
- don't polish the final matt coat
- don't apply over LJA99 that isn't fully cured
Storage
Safety: Two-pack solvent-borne material with an isocyanate hardener: flammable; spray in a booth, wear an A2P2 carbon respirator (air-fed preferred) and nitrile gloves. No product SDS found.
