Item Code: X-850-0000
Product Name: Urethane Dimethacrylate, UDMA, DUDMA, diurethane dimethacrylate
INCI: Di-HEMA Trimethylhexyl Dicarbamate

Our Urethane Dimethacrylate is a mix of isomers and is often used in light-cure systems. As a homopolymer, UDMA cures to form a hard, glassy surface that is low in color and bisphenol A free!  Various urethane dimethacrylates have been used in anaerobic adhesive applications. This material has also been referred to as diurethane dimethacrylate, DUDMA as well as Di-HEMA Trimethylhexyl Dicarbamate.


Performance Properties:

  • Fast curing
  • Low color
  • Customizable to meet your application

Typical Applications:

  • Light-curable, Dental Composite Base Resin
  • Predominant resin in UV-curable nail gels
  • Component in Anaerobic Adhesives
  • Energy-curable coatings

A variety of product applications and foreign regulations have restricted the use of  Hydroquinone (HQ) and 4-Methoxyphenol (MeHQ) as polymerization inhibitors.  In response, Esstech can offer the following products with non-detectable or limited levels of HQ and MeHQ:

The following monomers can be supplied with “non-detectable” levels of HQ and MeHQ as determined by GPC Analysis

  • X-943-7466   Triethyleneglycol Dimethacrylate, 100 ppm BHT
  • X-945-7466   Tetraethyleneglycol Dimethacrylate, 100 ppm BHT
  • X-844-7469  2-Methoxyethoxyethyl methacrylate, 500 ppm BHT
  • X-887-7466  1, 6-Hexandiol Dimethacrylate, 100 ppm BHT
  • X-947-7466  Trimethylolpropane Trimethacrylate, 100 ppm BHT
  • X-850-1066  Urethane Dimethacrylate, 150 ppm BHT
  • X-851-1066   Urethane Dimethacrylate IPDI, 500 ppm BHT

The following monomers can be synthesized with low or non-detectable levels of HQ and MeHQ but, the BHT analog of each is currently not part of Esstech’s commercial product offering.

  • X-726-0000  Exothane 9
  • X-930-0000  Exothane 10
  • X-894-0000   Exothane 32
  • X-846-0000   HEMA Maleate
  • X-821-2000   Methacroyloxyethyl Phthalate (MEP, PAMM)
  • X-753-0000   HEMA Succinate
  • X-865-0000   Pyromellitic Dimethacrylate (PMDM)

Radtech UV & EB 2012 Technology Expo and Conference

April 30 – May 2, 2012 at the Hyatt Regency in Chicago, Illinois

Esstech is excited to announce that two of their own will be presenting the upcoming Radtech UV & EB show!  Join us in Chicago and learn more about Esstech’s latest technology, the EXOTHANE™ Elastomers as well as the fundamentals of UV-curable nail gel formulations.

Dr. Mike Idacavage, Director, Business Development
Presenting: Exothane™ Elastomers: A New Series of Versatile Urethane (Meth)acrylates
A novel set of energy curable materials, urethane (meth)acrylates, have been developed. Results of this work indicate that these UV and EB curable urethanes have superior toughness at max strength compared to the controls. In an unusual and unexpected finding, these materials exhibit low shrinkage while at the same time demonstrating high conversion rates. The enhanced properties of the UV curable elastomers, specifically the high percent elongation and hardness, suggest that these novel materials could be used as functional key components to increase the toughness and durability of coatings in a wide range of industrial applications.   The combination of high conversion, low volumetric shrinkage and low shrinkage stress brings interesting attributes to a large variety of applications such as adhesives, photopolymer printing plates, floor coatings, etc.

Dr. Idacavage is also teaching:  UV/EB Professional Short Course: Undergraduate-Level, and chairing the following two sessions: Session: 13 – Photovoltaics & Electronics and Session: 14 – Barrier Coatings & Conductive Films For Flexible Electronics

Presenter:  Tom Barclift, Director, Sales and Marketing
Presenting: Chemistry and Formulation of UV Curable Nail Enhancements
The nail enhancement industry has evolved from chemical-cure, methyl methacrylate-based liquid and powder systems to UV-curable systems.  These systems are a precise mix of resins, additives, rheological modifiers and photoinitiators. The basic chemistry of these components will be discussed along with examples of typical formulation strategies.




Contact us in advance if you would like set-up a meeting while in Chicago.
Or, visit Booth # 426 during the Expo.
