In the rapidly evolving chemical industry, Cyclic Trimethylopropane Formal Acrylate (CTFA) has emerged as a pivotal UV-curing monomer, driving innovation in coatings, inks, and adhesives. As a flagship product of Shenzhen U-Sunny's AM-313 series, CTFA combines advanced performance with environmental sustainability, making it a preferred choice for industrial applications.
What is Cyclic Trimethylopropane Formal (CTFA)?
CTFA (CAS: 66492-51-1) is a monofunctional UV monomer with the molecular formula C10H16O4 and a molecular weight of 200.23 g/mol . Key properties include:
High purity (≥99%) with low acidity (≤0.05%) and water content (≤0.05%).
Low viscosity (10–25 cPs at 25°C) and excellent adhesion to plastics and metals .
Rapid curing, low odor, and resistance to yellowing, ideal for eco-friendly formulations .
Shenzhen U-Sunny's AM-313 variant further enhances these traits, offering a glass transition temperature (Tg) of 32°C, surface tension of 33.1 dynes/cm, and superior film toughness for UV-curable systems .
Applications in Coatings, Inks, and Adhesives
1. UV Coatings
CTFA-based formulations deliver high crosslinking density and chemical resistance, making them suitable for automotive, electronics, and industrial coatings. For instance, AM-313 reduces shrinkage during curing, enhancing adhesion on complex substrates like ABS and aluminum .
2. UV Inks
In the booming UV inkjet sector, CTFA's low viscosity and fast curing enable high-resolution printing on packaging and textiles. Its compatibility with pigments ensures vibrant colors without compromising durability .
3. UV Adhesives
CTFA improves flexibility (180°–360° foldability) and thermal stability in adhesives for electronics assembly and medical devices. Its low irritation profile aligns with stringent safety standards .
Market Trends and U-Sunny's Competitive Edge
