Semi-gloss paint based on polyurethane

  • Polyurethane paint (also called polyurethane) is a two-component product based on polyurethane resin and has a very short drying time.
  • Semi-gloss polyurethane paint is based on acrylic resin and isocyanate hardener, as well as surface-improving additives designed for the final layer. Suitable chemical and mechanical resistances in atmospheric conditions and under sunlight as well as acid rain are the advantages of this paint.
  • This paint is used as a final layer to cover the surfaces exposed to direct sunlight and harsh weather conditions due to its high resistance to moisture and excellent adhesion on a variety of surfaces and coatings.
  • Other properties of this paint include high resistance of this paint against scratches and abrasion led to the widespread use of this product in various industries.
  • This paint is one of the most common types of polyurethane in metal industries and industrial topics.

• This paint and its thinners are flammable, so it should be stored in a sealed container away from fire, heat, strong current and incendiary materials. • To increase the durability of the dishes, they should be kept away from water or moisture, and if the dishes are opened, it is recommended to use them in the shortest possible time. • Warehouse temperature should be between ℃ 10 to ℃ 30 and the warehouse should be well ventilated. • It is necessary to use the paint before the expiration date to ensure the proper quality and health of the paint.

• Mix the appropriate polyurethane paint and hardener in the appropriate proportions and dilute with the appropriate thinner until the accepted viscosity. • Stir the polyurethane paints thoroughly during preparation and before consumption. Due to Pot Life, prepare only the required amount of paints because they have a high drying speed (the pot life of the prepared paint is 6 hours). • To use polyurethane paints, the surfaces must be completely dry and free of any salt, grease, dust and any other impurities. For this purpose, the surface can be cleaned with fresh water. • • If there is any rust or corrosion on the surface, it should be removed from the surfaces according to the usual methods and a suitable priming system should be applied on it. • The surface is prepared and washed according to SSPC-SP standard. • To use this type of paint, brushes with dimensions of 8 to 12 inches (20 to 30 cm) are a good choice for this project. • in choosing a brush is should be noted that brushes with natural wool that easily collect dirt should not be selected • When applying the polyurethane coating, long and uniform strokes should be used to create a thin layer of polyurethane on the surface. • For best results, it is recommended to avoid applying a large amount of paint at one point or passing the brush several times at a specific point, as this will cause bubbles and defects in the final coating.
