With the increase in environmental awareness, 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 physical properties such as rapid drying and good adhesion. Triethylenediamine (TEDA) plays an important role in environmentally friendly coating formulations as a multifunctional additive. This article will discuss in detail the rapid drying and excellent adhesion of TEDA in environmentally friendly coatings, and provide relevant product parameters and usage suggestions. <\/p>\n
Triethylenediamine (TEDA), with the chemical formula C6H12N2, is a colorless to light yellow liquid with a strong ammonia odor. TEDA is a strong basic compound with good solubility and reactivity. Its main physical and chemical properties are shown in the following table:<\/p>\n

Application background of TEDA in environmentally friendly coatings<\/h2>\nThe development trend of environmentally friendly coatings is to reduce the emission of harmful substances and improve the performance and service life of the coatings. As an efficient catalyst and crosslinking agent, TEDA can significantly improve the drying speed and adhesion of the coating while reducing VOC emissions. thereforeTEDA is increasingly widely used in environmentally friendly coatings. <\/p>\n 4. Rapid drying effect of TEDA in coatings<\/h2>\n |
