HH2784 is a carboxyl polyester resin designed for 70/30 hybrid powder coatings.
As a kind of paint with zero VOC emission, powder coating has the characteristics of high efficiency, resource saving, environmental protection and excellent comprehensive performance. Compared with traditional solvent-based coatings, powder coatings have obvious advantages. In many fields, powder coatings are gradually replacing traditional solvent-based coatings. At present, powder coatings have been widely used in the decorative coating and protection of most metals such as furniture, home appliances, toys, automobiles, high-speed guardrails, and aluminum alloy windows.
Although powder coatings have environmental advantages, with the tightening of environmental regulations, some application fields with skin contact and food contact characteristics have also restricted the raw materials used. In recent years, there have been several non-industrial poisoning incidents related to chemical substances in coatings, which have attracted great attention from all parties. Relevant departments have also issued relevant restrictive laws and regulations. For example, the EU REACH regulations clearly limit the amount of organotin in powder coatings. content, IKEA stipulates that tin should not be contained in polyester powder coatings for toys and furniture. On June 27, 2018, EU REACH officially issued a notice to include trimellitic anhydride (TMA) in the SVHC candidate list, and pointed out that TMA has respiratory sensitization. If the exposure time is prolonged and no intervention measures are taken, trimellitic anhydride will cause serious damage to lung function. permanent damage.
As the main raw material of polyester powder coating, polyester resin plays a decisive role in the health and environmental protection characteristics of powder coating. HH2784 does not contain TMA, which fully meets the environmental protection requirements of EU REACH.
