LZC1051

LZC1051 PU thinner (Milesi 'Diluente per PU extra')

Thinner for polyurethane materials (official). Milesi calls it 'PU extra thinner': medium evaporation, for PU topcoats at a medium temperature of 18–22 °C.

  • Reducing Milesi 2K PU lacquers and primers (LGA, LDA, LQA, LBA, LBR) to spray viscosity
  • Reducing the exterior 2K acrylics LGA180 and LKR181
  • 2–3 % extra LZC1051 (or LTC4 instead) to improve flow-out of LGA20-series PU lacquers
  • Reducing the LGA190 PU parquet lacquer (alongside LZC8643) 10–30 %

Mixing matrix

  • LZC1051Additive
    % by weight: 2–3 %datasheet

    To improve flow-out on LGA20-series PU lacquers — 2–3 % of LZC1051 or, alternatively, LTC4.

    LZC1051 and LTC4 are alternatives, not used together. LTC4 is not in Technocolor's catalogue.

Percentages are per 100 parts of component A.

Gun flush
Fine for flushing the gun between coats of the same PU; for a full clean-down Milesi lists acetone-based LZC1000.recommended

The thinner is not applied on its own; nozzle and pressure follow the product being reduced (see the LGA21, LBR40, etc. records).

Process and compatibility

How to add
Mix part A with the hardener first, then add LZC1051 and stir.; Dose by weight on a scale; % is of part A unless the product sheet says otherwise.; Add in steps, checking viscosity with a DIN4/Ford 4 cup.recommended
