Flow Star Urethane Reducers



A non-photochemically reactive, alcohol and water-free, urethane grade reducer. Use in any urethane undercoat or clearcoat. Recommended for European type basecoats. 100% virgin solvent.


Many basecoat systems require the use of a “Stablizer” or a “Converter”, which is added to the basecoat color. These products are designed to initiate a very fast cure, or a very fast flash time of the basecoat. This is achieved with products that quickly evaporate from the basecoat film or products that induce a reaction of the resins. The objective of these products is to prevent the aluminum flakes in the basecoat from moving or “mottling”.

Each major paint company has formulated a separate method of “stabilizing” or “converting” their basecoat colors. 5 Star Autobody Products has duplicated three of the most popular Basecoat Systems:
PPG: Reactive Reducers
Dupont: Basemaker Reducers
Sherwin Williams: Basecoat Stabilizer

5 Star Flowstar Urethane Reducers are formulated to be used to thin primer surfacers, clearcoats and European colorcoats.

• Direct offset to major paint companies
• Prevents “mottling” of metallics
• Fast Drying
