Cyclic Trimethylopropane Formal (CTF), a versatile chemical intermediate, plays a pivotal role in the synthesis of high-performance materials for industries such as coatings, inks, and adhesives. As a leading product in this domain, Shenzhen U-Sunny's AM-313 exemplifies innovation and efficiency in UV-curable systems. This article explores the synthesis methods, industrial applications, and market trends of CTF-based products, with a focus on AM-313's unique advantages.
What Is Cyclic Trimethylopropane Formal?
Cyclic Trimethylopropane Formal (CTF) is a cyclic ester derived from trimethylolpropane, widely recognized for its role as a UV-reactive monomer. With a molecular formula of C10H16O4 and a molecular weight of 200.23, CTF exhibits low viscosity (10–25 cps at 25°C), high purity (≥99%), and excellent chemical stability . Its synthesis typically involves acid-catalyzed dissociation of trimethylolpropane production residues, achieving a yield exceeding 90% and purity above 98.5% after distillation .
