LHR4010
LHR4010 white gloss PU converter (tint base / white high-gloss 2K PU enamel)
White high-gloss 2K polyurethane converter — a tint base for light and pastel colours; untinted it is a white gloss PU enamel. Excellent scratch resistance, good hiding and flow-out, and it holds well on edges (doesn't pull back off the arrises). Spray at 120–160 g/m² or curtain-coat at 130–150 g/m². Hardener LNB110 at a heavy 80 % by weight; thinner LZC8643 (slow PU) at 40 % by weight.
- Gloss white and tinted (light/pastel) MDF fronts, including routed profiles — good build on edges and end grain
- Case furniture: flat parts on a curtain-coater line (sides, shelves, doors)
- Surfaces that need scratch resistance — kitchens, cabinet tops, kids' furniture

Answers are based on the LHR4010 data and the products it mixes with.
Mixing matrix
- LNB110Hardener% by weight: 80 %official% by volume: 110 %official
Always — the only hardener listed.
By volume there is more hardener than base (110 %) — that's correct for LHR4010, don't confuse it with KHR1 (50 % by weight). Weigh rather than measure by cup. Mix thoroughly, let it stand 5–10 min.
- LZC8643Thinner% by weight: 40 %official% by volume: 60 %official
Standard thinner (slow PU) — for spray and curtain coating.
Slow thinner gives flow-out on gloss; in a cold shop (<18 °C) it stretches the dust-free time.

Application
HVLP
- Recoat
- after overnight dry (12–16 h) and denibbing; or wet-on-wet within ~15 minrecommended
- Sanding between coats
- P500–P600 (or K600 mat), dust off thoroughlyrecommended
Gun 15–20 cm, 50–75 % overlap, fan fully open. Hit edges and end grain with a banding pass first. Don't sand the final gloss coat unless you plan to polish it (not before 72 h).
Conventional spray
Airmix (air-assisted airless)
Curtain coater
Flat or lightly profiled parts only. Watch the viscosity in the head — the hardener is already in and the mix thickens; top up with fresh mix, not just thinner. Flush the head with LZC8643 before the pot life runs out.
Electrostatic
- Why ru
- Официальных упоминаний для LHR4010 нет; общие рекомендации с https://www.t-color.ru/information/methods/
Not stated. The methods page says any spray system can be electrostatic, but check the mix conductivity for a PU on slow thinner first.
Process and compatibility
- Substrate preparation
- MDF: sand P150–P180–P220, MDF sealer, 1–2 coats white PE or PU primer, sand P280–P320 (P400 under gloss), de-dust.recommended
- Sanding
- Primer P280–P320 (P400 under gloss); between enamel coats P500–P600; polish after 72 h at the earliest.recommended
- Polishing
- Can be polished after full cure (≥72 h, better 5–7 days) with 3M Finesse-it compounds as in the official schedule; heavy buffing on tinted pastels can shift the shade.recommended
- Temperature and humidity
- Work at 18–25 °C, never below 15 °C; RH 50–70 %; forced dry at 30–35 °C.recommended
- Don'ts
- Don't mix it up with KHR1's ratio: LHR4010 takes 80 % hardener by weight (110 % by volume)
- Don't use the mix past its pot life or 'revive' it with thinner
- Don't tint dark colours on a white base — use a clear converter
- Don't apply over uncured or unsanded primer
- Don't polish before 72 h
- Don't work below 15 °C
Storage
- Shelf life
- 8–12 months in the unopened canrecommended
- Storage temperature
- +5…+25 °C, tightly closed, away from moisturerecommended
