523486 - LESONAL Slow Multi thinner HT 1L for primer 540 2K

Features

• Reference: 523486
• Name: Multi Thinner HT (High Temperature)
• Recommended use: hot conditions (practically, above approximately 30 °C)
• Role: adjustment of viscosity and evaporation kinetics in hot climates
• Brand-announced compatibilities: 1K Etch Primer, 2K Epoxy Primer, 2K Universal Plastic Primer

Workshop advantages

When the temperature rises, evaporation accelerates and the film tension window reduces. An “HT” thinner helps keep a film open long enough to improve application consistency, especially on large surfaces.

• Promotes a more homogeneous flow in hot conditions.
• Limits risks associated with too rapid drying (more “dry” appearance, more pronounced transitions).
• Improves spray stability when the workshop or booth is very hot.

When to choose the 523486

The Multi Thinner HT is relevant whenever the actual temperature (workshop, booth, panel) is high, or when the air is very dry and the product “pulls” quickly. It fits into a simple stock logic, alongside faster/standard versions for cooler seasons.

Usage tips

To avoid any mistakes, always start from the technical data sheet of the product to be thinned (primer): it sets the percentages, evaporation times, and gun settings. The choice of thinner (Fast / Standard / HT) then adapts the kinetics to the workshop conditions.

• Measure or estimate the actual temperature (booth, room, panel), not just the weather.
• Favor a stable gun setting (flow/pressure/distance) before increasing dilution.
• Respect evaporation times between coats and avoid local overloads.

Common mistakes to avoid

• Using a too fast thinner in high heat (risk of less smooth appearance and uneven application).
• Over-diluting “to compensate”: this can weaken the film and degrade durability.
• Exceeding compatibility limits: always check the product TDS and system recommendations.

Actionable checklist before application

• Actual temperature > ~30 °C: the HT choice becomes coherent.
• Ratios and settings compliant with the TDS of the product to be thinned.
• Quick test on a sample piece if extreme conditions (heatwave, very dry air).
• Gun setting validated before adjusting dilution.
• PPE and SDS respected (product reserved for professional use).

Features (search)

The Lesonal thinner 523486, also known as Multi Thinner HT, is a multi-purpose thinner designed for bodywork tasks performed in high temperatures. It allows for viscosity adjustment and better control of evaporation kinetics when the workshop or booth exceeds approximately 30 °C, to achieve more consistent application and a more homogeneous finish.

FAQ

Is the 523486 reserved for summer?
It is mainly useful when it is hot or when the booth is very high in temperature. In cooler conditions, a standard/faster thinner is often more suitable.

Can I use it instead of a Standard or Fast thinner?
It is not recommended systematically: below the “hot” range, you may unnecessarily extend evaporation. The best practice is to adapt the thinner to the actual temperature.

Is it a thinner for clears?
The 523486 is a multi-thinner positioned by the brand for certain primers. For a clear, always refer to the TDS of the concerned clear and the explicitly recommended thinners.

What does reference 523486 correspond to?
It is the Lesonal reference for the Multi Thinner HT.
