Solvent-borne pigment stain (CPS + CFC3 binder + S90) under a UV-curing acrylate build: 100 %-solids UV filler + 2 UV roller sealer coats; topcoat either a 100 %-solids UV roller lacquer (matt) or a solvent-containing UV curtain lacquer (gloss). All UV materials are 1K — no hardener, no pot life.
UV finishing of flat anegre-veneered panels
- Substrate
- Flat furniture panels veneered with anegre (a pale, even-grained African hardwood), pigment-stained
- Result
- Stained, closed-pore anegre: variant (a) thin matt topcoat (~30 gloss, natural-wood look); variant (b) thick high-gloss lacquer (~100 gloss) that can be polished.
- 01
Sand the veneer
Abrasive: P150, P180, P220
Abrasive belt, P150 → P180 → P220 in sequence. Anegre veneer is thin — don't sand through to the glue line; blow off/brush the dust after P220.
- 02
Apply stain
- 03
Dry the stain
Drying: [object Object] °C, 5 min
The solvent must be gone before the rollers, or the UV filler will smear the stain. Allow longer in a cold shop.
- 04
Roll on UV filler
VTS20011 100 %
- Consumption
- 30–35official
UV filler-primer, 100 % solids (catalog): fills anegre's pores and bonds to the stained veneer.
- 05
UV cure (gel)
Drying: ≈ seconds under the lamps (conveyor 10 m/min)
Single-lamp gel cure: the film sets but stays reactive enough to bond the next UV coat without sanding.
- 06
Roll on sealer, coat 1
VTS20029 100 %
- Consumption
- 20–25official
Apply straight after the filler's gel cure — no sanding in between.
- 07
UV cure (gel)
Drying: ≈ seconds under the lamps (conveyor 10 m/min)
Single-lamp gel cure: the film sets but stays reactive enough to bond the next UV coat without sanding.
- 08
Roll on sealer, coat 2
- 09
UV cure (full)
Drying: ≈ seconds under the lamps (conveyor 10 m/min)
Full cure under three lamps: once the panel cools it can be sanded, stacked or packed.
- 10
Sand the sealer
Abrasive: P240, P280, P320
Abrasive belt P240 → P280 → P320 once fully cured and cooled. Don't cut through to the stain (watch the panel edges) — you can't patch it later. De-dust.
- 11a
Matt finish: roll on topcoat
VTL20030 100 %
- Consumption
- 8–12official
A thin 8–12 g/m² coat gives an even matt, natural-wood look; most of the film build comes from the sealer.
- 12a
UV cure (full)
Drying: ≈ seconds under the lamps (conveyor 10 m/min)
Final cure under three lamps. Stack/pack once the panels have cooled.
- 11b
Gloss finish: curtain-coat the lacquer
VTL30100 100 %S31 20 % (Thinner)
- Nozzle
- 0.5–1 mm slot (lip) gaprecommended
- Consumption
- 120–150official
The lacquer contains solvent (64 % solids per catalog), so it must be flashed off before the lamps (step 12b). Dust is the main enemy of gloss: clean zone, de-dust after P320.

Pot life of the mix: not applicable (1K); keep shielded from UV/daylight, top up thinner to hold viscosity.

Pre-dry (flash-off)
Drying: [object Object] °C, 5 min
5 min at 30–35 °C drives out the solvent while the TL03/05 actinic tubes lightly pre-gel the surface. Trap solvent under the UV lamps and you get pinholes, bubbles and lost gloss.
- 12b-2
UV cure (full)
Drying: ≈ seconds under the lamps (conveyor 10 m/min)
Final cure under three lamps. Per the catalog VTL30100 can be polished — polish after cooling, safer after 24 h.

- Сухой слой ≈ г/м² × сухой остаток ÷ плотность (~1,1 г/см³ для УФ-акрилатов). УФ-шпатлёвка + изолирующий грунт: 70–85 г/м² при ~100 % → ~65–77 мкм (часть уходит в поры и сошлифовывается P240–P320). Матовый финиш 8–12 г/м² ≈ 7–11 мкм. Глянцевый финиш 120–150 г/м² при 64 % (или ~51 % при разбавлении на 25 %) → ~55–87 мкм. Морилка измеримой плёнки не даёт.

- Хронометрируются только: высыхание морилки 5 мин (+ предварительная сушка глянца 5 мин); УФ-отверждение занимает секунды при 10 м/мин. С учётом транспортёра, двух проходов шлифовки и охлаждения перед шлифовкой/штабелированием → ≈15 мин для матовой и ≈20 мин для глянцевой панели от входа до выхода на непрерывной линии. Полировка глянцевого варианта: плюс ~24 ч (расчётно). На реальных линиях зависит от длины.
