Cyclic Trimethylopropane Formal (CTFA): A Key UV-Curing Monomer for Coatings, Inks, and Adhesives

Apr 25, 2025 Leave a message

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

The global CTFA market is transitioning from import reliance to domestic production dominance, driven by Chinese manufacturers like Shenzhen U-Sunny. Key trends include:

Export growth: With mature production technologies, China is poised to supply CTFA to Europe and North America .
