Polyurethane Thinner

Polyurethane Thinner is a special solvent blend for 2K polyurethane paints and varnishes. It provides strong solvency, controlled evaporation, smooth flow, and excellent film leveling, helping achieve a more uniform and glossy final finish. It is suitable for professional use in industrial and decorative polyurethane coating systems.

Where it is used

Polyurethane Thinner is used for:

  • thinning 2K polyurethane paints and varnishes
  • adjusting viscosity in polyurethane coating systems
  • spray application with conventional or airless equipment
  • cleaning painting tools after using polyurethane products
  • industrial and metal surfaces requiring a durable polyurethane finish
Why choose Polyurethane Thinner

Polyurethane Thinner helps with:

  • proper adjustment of application viscosity
  • smoother spray application
  • uniform film formation
  • improved final finish
  • cleaning equipment used with PU paints or varnishes
Suitable for
  • 2K solvent-based polyurethane paints
  • polyurethane varnishes
  • industrial coating systems
  • decorative polyurethane finishes
  • spray application
  • cleaning spray guns, containers, and painting accessories
