LZC70
LZC70 slow PU thinner
Slow thinner for polyurethane and acrylic materials. Used instead of LZC8643 when you need more open time: a hot shop, large flat panels, curtain coating, and high-gloss finishes where flow-out matters.
- Reducing LUA460/LUA462 acrylic lacquers (20–30 %)
- Reducing KDA1 converter (20–40 %) and KHR1/KGA1/KKR1 pigmented PU topcoats (per dealers)
- Reducing LJA99 acrylic sanding sealer (10–30 %, per dealer)
- Slower alternative to LZC8643 for hot conditions and big flat panels

Characteristics

- slowofficial
- Compatible binders
- polyurethane,acrylicofficial
Process and compatibility
- Temperature and humidity
- Above ~25 °C, on large horizontal panels, for curtain coating and for gloss where flow-out matters. At 18–22 °C on verticals use LZC8643 (less sag and dust).recommended
- Don'ts
- Do not exceed the dose on the material's own sheet (30 % for LUA460/462, 40 % for KDA1).
- Not for waterborne materials.
- Don't lay heavy coats on verticals — slow solvent sags.
- It does not change full cure time, only flash-off and flow-out.
Storage
- Shelf life
- not stated — typically years in a closed canrecommended
- Storage temperature
- closed can, away from ignitionrecommended
Safety: Flammable liquid. Use in a ventilated spray booth with an organic-vapour (A2) respirator and nitrile gloves. Keep away from flames and sparks.
