Rapid curing of reactive low-odor amine catalyst ZR-70 in environmentally friendly coatings<\/h1>\n

Introduction<\/h2>\n

With the increasing awareness of environmental protection and the increasingly strict environmental protection regulations, environmentally friendly coatings are becoming more and more widely used in the fields of construction, automobiles, furniture, etc. Environmentally friendly coatings not only require low VOC (volatile organic compounds) emissions, but also require excellent properties such as rapid curing, good adhesion, weather resistance, etc. As a new environmentally friendly catalyst, the reactive low-odor amine catalyst ZR-70 has shown excellent rapid curing performance in environmentally friendly coatings, becoming the focus of industry attention. <\/p>\n

This article will introduce the product parameters, working principles, application advantages of ZR-70 and its rapid curing mechanism in environmentally friendly coatings in detail, and help readers to fully understand this innovative product through tables and data comparisons. <\/p>\n

2. Working principle of ZR-70<\/h2>\n

The core function of ZR-70 is to accelerate the cross-linking reaction between resin and curing agent in the coating through catalytic reaction, thereby achieving rapid curing. Its working principle mainly includes the following aspects:<\/p>\n

    \n
  1. \n

    Catalytic Activity<\/strong>
    \nZR-70 molecules contain highly active amine groups, which can react with epoxy groups or isocyanate groups in the coating, significantly reducing the reaction activation energy and thereby accelerating the curing process. <\/p>\n<\/li>\n

  2. \n

    Low Odor Characteristics<\/strong>
    \nZR-70 has undergone special process treatment to remove volatile components in traditional amine catalysts, so that it produces almost no irritating odor during the curing process, and meets environmental protection requirements. <\/p>\n<\/li>\n

  3. \n

    Response Selectivity<\/strong>
    \nZR-70 is highly selective for the reaction between resin and curing agent, and can achieve efficient catalysis at lower temperatures, while avoiding side reactions and ensuring the stability of coating performance. <\/p>\n<\/li>\n

  4. \n

    Environmental Adaptation<\/strong>
    \nZR-70 can maintain efficient catalytic activity within a wide temperature range (5\u00b0C-40\u00b0C), and is suitable for construction environments under different climatic conditions. <\/p>\n<\/li>\n<\/ol>\n
