It is obtained as a result of the reaction of components such as polyurethane thinners, polyols and isocyanates. They are chemicals that are generally used for thinning, diluting or adjusting the mixture properties of resins. It allows to control the reaction rate. Fast reactions provide faster curing, while slower reactions offer longer processing times. Provides viscosity control, provides a lower viscosity mixture, easier application and spreading. Polyurethane thinners give users flexibility to tailor resins to specific needs. It helps to ensure a homogeneous mixture between the resin and hardener components. This improves the quality and performance of the product. Polyurethane thinners are generally chemically stable, allowing them to be used in applications where resin blends may be exposed to different environmental conditions. Polyurethane thinners are generally colorless and transparent, so their addition to resin blends usually does not affect the color or appearance of the final product.
