Cyclic Trimethylolpropane Formal Acrylate (CTFA) is a high-performance monofunctional cyclic acrylate monomer featuring a unique cyclic acetal structure. It combines comprehensive advantages including low viscosity, high dilution efficiency, low shrinkage, high flexibility and excellent adhesion. Specially designed for UV/LED curing systems, it is widely used in high-end coatings, inks, adhesives, 3D printing and other fields.

1. Core Performance Features

1) Ultra-low viscosity & high dilution efficiencyWith a viscosity of only 10–25 mPa·s, it significantly reduces system viscosity, improves application flow and reduces the usage of high-viscosity resins.

2) Low shrinkage, low stress & high flexibilityThe cyclic structure greatly reduces curing volume shrinkage, minimizing cracking and warping; the cured film delivers outstanding flexibility and bending resistance, balancing hardness and toughness.

3) Excellent adhesionProvides strong adhesion to substrates such as plastics (ABS/PC/PMMA), metals, glass and ceramics, making it suitable for difficult-to-bond materials.

4) Low odor, low irritation & eco-friendlyExtremely low odor, low skin irritation and low VOC content, meeting environmental requirements for food contact, cosmetics, interior applications and more.

2. Main Application Fields

1) UV Coatings: plastic coatings, wood coatings, metal coatings, vacuum plating primers, fiber optic coatings

2) UV Inks: lithographic, flexographic, gravure and inkjet inks

3) UV Adhesives: pressure-sensitive adhesives, sealants, laminating adhesives, optical adhesives

4) 3D Printing: SLA photopolymer resins, DLP resins (toughening and viscosity reduction)

5) Others: UV nail gels, dental materials, photoresists, waterborne UV systems
