When your UV-curable formulations demand exceptional heat resistance, uncompromising hardness, and superior durability, SINOMER® THEICTA stands out as the industry's premier trifunctional acrylate monomer. With its unique triazine ring structure and three reactive acrylate groups, THEICTA delivers a combination of properties that few other monomers can match.
As one of the highest glass transition temperature (Tg) acrylates available — exceeding 250°C — SINOMER® THEICTA enables coatings, adhesives, and inks that maintain their integrity even under the most demanding conditions . Whether you're formulating for automotive coatings, electronic encapsulation, or high-speed printing, THEICTA provides the backbone for truly durable systems.
SINOMER® THEICTA features a glass transition temperature exceeding 240°C — among the highest of any UV/EB curable acrylate . This exceptional thermal stability ensures that cured films retain their hardness, structural integrity, and performance properties even under prolonged heat exposure. Applications requiring reflow soldering (up to 260°C) or continuous high-temperature service are ideal candidates for THEICTA-based formulations.
With three acrylate groups per molecule, THEICTA offers high crosslinking density and rapid polymerization under UV or electron beam exposure . This high reactivity translates to:
Faster line speeds in production
Lower energy consumption
Reduced oxygen inhibition issues
Immediate handling and stacking capability
The high crosslink density achieved with THEICTA creates a rigid, three-dimensional polymer network that delivers:
Outstanding surface hardness — ideal for protective coatings
Excellent scratch and mar resistance — maintains appearance over time
THEICTA's triazine ring structure provides inherent resistance to a wide range of chemicals . Cured films demonstrate excellent durability against:
Organic solvents (acetone, alcohols, toluene)
Acids and alkalis
Water and humidity (both immersion and condensation)
Oils and greases
Despite its high crosslink density, THEICTA exhibits low volume shrinkage during curing . This characteristic, combined with its polar triazine core, promotes:
Superior adhesion to metals (aluminum, steel), glass, and various plastics
Reduced internal stress in thick films
Better dimensional stability in precision applications
THEICTA-based coatings exhibit excellent optical clarity and high gloss . The cured films remain water-white and resist yellowing even under extended UV exposure or high temperatures, making them suitable for clear coats and optical applications.
*Note: THEICTA is a crystalline solid at room temperature (melting point ~52-54°C) and requires gentle heating (50-60°C) for incorporation into liquid formulations . For applications requiring a ready-to-use liquid version, please inquire about our specialized liquid grades.*

Sinocure Chemical Group manufactures SINOMER® THEICTA to strict quality standards, ensuring:
Consistent batch-to-batch purity (>99% typical)
Stable inhibitor levels for reliable processing
Comprehensive technical support for formulation development
Reliable supply chain with responsive customer service
Leading global suppliers of UV/EB materials offer THEICTA (often under trade names like
) as a key component in their high-performance portfolios . SINOMER® THEICTA provides the same exceptional quality and performance, backed by Sinocure's commitment to excellence.
Due to its crystalline nature, SINOMER® THEICTA should be heated to 50-60°C to melt before incorporation into formulations. It is compatible with:
Most acrylate oligomers (epoxy acrylates, urethane acrylates, polyester acrylates)
Common reactive diluents (TMPTA, TPGDA, HDDA, etc.)
Standard photoinitiators (Type I and Type II systems)
| Formulation Type | Typical Concentration |
|---|---|
| Hard Coatings | 20 – 50% |
| Printing Inks | 5 – 25% |
| Adhesives | 10 – 40% |
| 3D Printing Resins | 10 – 35% |
Optimal dosage should be determined through formulation-specific testing.
Shelf Life: 12 months from date of manufacture under recommended conditions
