ATL2
ATL2 acrylic converter (tinting base) for pearlescent and metallic enamels
Two-pack clear acrylic (acrylic/isocyanate, AC40-cured) converter — the base for making pearlescent and metallic enamels by tinting with CS pastes. The formulation orients the pearl flakes evenly through the film for a deep pearl lustre. High physical/chemical resistance, non-yellowing.
- Making acrylic pearlescent and metallic enamels (tinted with CS 00xxx pastes)
- Decorative finishing of wood items (incl. MDF) over an opaque base enamel
- Finishing metal, PU foam (PPU) and glass items (per CS paste catalogue)
- Interior use only

Mixing matrix
- AC40Hardener% by weight: 20 %official% by volume: 20 %official
Always — fixed 20 % (not a range, unlike ATL1/APL1 at 10–20 %).
AC41 is not listed for ATL2 — don't substitute without a test panel.
- % by weight: 20–30 (typ. 25) %official% by volume: 25–35 (typ. 30) %official
S50 — normal evaporation, the default; S80 — slow, above ~25 °C and on big panels. On pearl, S80 keeps the film open longer so flakes lie flatter, but sag risk goes up.
These are the official product-page figures (20–30 % by weight, 25–35 % by volume).
- % by weight: 30–40 %catalog
2025–2026 catalogue variant: 30–40 % (weight/volume not distinguished).
Conflicts with the official page (20–30 % by weight). For pearl, stay toward the low end — heavy thinning gives mottling/clouding and uneven flake orientation. The catalogue may simply repeat the ATL1 line.

Tinting — stir the paste into the converter before adding hardener; pastes can be blended.
10 % max. Mix well — pearl flakes settle.
- D1570Additive% by weight: 3 %catalog
Glass only: in the first (adhesion) coat of acrylic over degreased glass.
Catalogue gives 3 % for acrylic coatings generally, not ATL2 specifically; later decorative coats go without it.

Alternative to D1570 for acrylics on glass.

- Technique
- 15–20 cm distance, 50–75 % overlap, constant speed and distance; a final slightly drier drop/mist coat from a bit further back evens out flake orientation.recommended
Technocolor only states 'spray, 150 g/m²'. Strain through a 190 µm filter (no finer — it'll catch the pearl) before loading the cup.

Conventional air spray is the universal method (official methods page); finest atomisation — good for pearl, but wasteful.

Fine for production runs; on pearl watch the fan pattern — an uneven fan shows as striping.
Process and compatibility
- Substrate preparation
- Primed (PPS20 white, 2 coats) and enamelled surface — PPL RAL 9005 black in Technocolor's example. The base colour sets the final pearl shade.catalog
- System
- [object Object],[object Object],[object Object],[object Object]catalog
- Goes under
- ATL200
- Sanding
- Base enamel: P320–P400 and de-dust. DO NOT sand the pearl layer; if needed, sand only the clear topcoat after it's applied.recommended
- Temperature and humidity
- 18–25 °C, RH 50–70 %; S80 above ~25 °Crecommended
- Don'ts
- Don't go over 10 % CS paste in ATL2
- Don't sand or polish the pearl coat
- Don't leave pearl without the clear gloss topcoat
- Don't lay it on heavy — sags and clouding
- Not for exterior use (CS pastes are interior-only)
- Don't swap AC40 for another hardener without a test
Storage
- Shelf life
- ≈12 months unopenedrecommended
- Storage temperature
- +5…+30 °C, tightly closed, away from heat/sparksrecommended
- Packaging
- check the can — not publishedrecommended
Safety: Contains organic solvents and, once mixed with AC40, isocyanates: spray in a ventilated booth, wear an A2P2/A2P3 respirator, gloves and goggles. Flammable — keep away from ignition sources.
