Product Name: 4-methacryloxyethyl trimellitic anhydride
Synonyms: 4-META, 4-MET (anhydride ring opens becoming di-carboxylic acid)
CAS#: 70293-55-9
4-META is an acidic monomer that can serve as a reactive primer in dental adhesive systems. 4-META is a high performance monomer that interacts with the tooth substrate, creating excellent adhesive bonds to dentin and enamel. Upon hydrolysis, the anhydride ring opens forming two carboxylic acid groups capable of demineralization as well as salt formation with calcium, strontium and other metals.

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.

From its simple origins in the early 1990′s as a line of highly customized raw materials for compounders of “new generation” restorative dental composites to now a major manufacturer of customized UV/EB curable materials serving an ever-wider range of industries, Esstech, Inc. has indeed been a very successful “experiment”. It is my pleasure to announce two additions to the Esstech Team of talented professionals.
Last year, Bruce Farina, a 21-year veteran of Sartomer Company, joined Esstech as Senior Vice President and we are now pleased to announce that, effective as of January 1, 2012, Bruce has been given full operational responsibility for Esstech as President/COO. Bruce’s two decades of experience at Sartomer ranged from Manufacturing Manager through various titles and functions to Vice President with, most recently, overall global responsibility for all of Sartomer’s photocure (UV/EB) business.
Bruce is taking over for Howard Slaff who, after a very successful leadership tenure at Esstech, is moving ten miles south down I-95 to assume the President/COO responsibilities being vacated by the retiring Mike Norquist at Esstech’s sister company, Esschem, Inc..
I am also very pleased to announce that Bruce has successfully recruited Dr. Mike Idacavage as Esstech’s new Director of Business Development. Mike Idacavage may be known to some of you as the immediate past-President of RadTech North America and is a lifetime member of RadTech’s Board of Directors. Mike’s “day job” for the last 15 years was with Cytec Industries (and, pre-merger, UCB Chemicals), most recently as Cytec’s Principal Research Fellow.
Those of us involved with Esstech over the years could not be more excited with the Team now in place and with their commitment to its next phase of customer-centric growth!

Chairman

Do not sacrifice conversion and the risk of residual monomer contamination to achieve low-shrink properties. New testing has demonstrated that EXOTHANE(TM) Elastomers have low shrinkage stress, low volumetric shrinkage, AND high conversion.
- Exothane 8, 94% Conversion, 3% Shrinkage, high % elongation
- Exothane 26, 96% Conversion, 4% Shrinkage, increased flexibility/toughness
- Exothane 32, 97% Conversion, 3% Shrinkage, low color and low viscosity
This new data, in addition to superior toughness, tensilse strength and percent elongation make the EXOTHANE product line ideal form many applications including, low-shrink dental restoratives, non-curling industrial coatings, unique UV nail enhancements, tougher anaerobic adhesives and more.

Item Code: X-846-0000
Product Name: Methacryloyloxyethyl Maleate
CAS#: 51978-15-5
EINECS(I): 257-569-5
INCI: HEMA Maleate
HEMA maleate is a carboxylic acid-containing methacrylate that can function as an alternative to PMDM. It has been used in anaerobic adhesive applications and is approved for use in cosmetic products.
The carboxylic acid group of X-846-0000 has the ability to improve adhesion to keratin. Its’ monomethacrylate functionality allows it to be incorporated into soak-off systems without detriment to “removability”. HEMA maleate’s low viscosity also makes it an ideal, reactive diluents.

Characterization of a nanoparticle-filled resin for application in scan-LED-technology
Eva Kolb, Claudia Kummerlöwe and Martin Klare
Abstract
Scan-LED-technology is a new rapid prototyping technique with increasing applications in the production of custom-made medical products. The present work is dealing with the examination of a silica/ urethandimethacrylate (UDMA) nanocomposite for application in scan-LED-technology. The use of specific LED in a photo-DSC unit enables the simulation of crucial parameters of nanoparticle-filled resins for their application in scan-LED-technology. The conversion of double bonds during the curing reaction and the rate of conversion were studied as a function of radiation intensity, silica nanoparticle content, and silanization of the nanoparticles with 3-methacryloyloxypropyl-trimethoxysilane (MPTMS). The conversion of double bonds is increasing with increasing radiation intensity. The increasing conversion of the nanoparticle-filled resins is discussed as a combined effect of increasing nanoparticle content, alternated initiator/double bond ratio and increasing radiation intensity. A significant dependence of the reaction rate on nanoparticle content could not be found. Only for the unfilled resin, the rate was increasing at higher radiation intensities. The influence of residual solvent on conversion and rate of reaction was also analyzed. TGA measurements combined with FTIR were used to study the silanization of the nanoparticles. The silane layer thickness on the surface of the silica nanoparticles was determined. -

Optimize Photocurable Mechanical Properties
EXOTHANE™ Elastomers represent the most recent advances in Esstech’s urethane chemistry. These versatile materials offer performance enhancements across a broad range of demanding formulations.
- Exothane 8, low color urethane, creates a “soft” yet tough polymer with high elongation
- Exothane 26, high flexibility when cured, has the ability to re-adhere at lower tensile strength
- Exothane 24, high crosslink capacity, low in color and viscosity and very high Shore D hardness
- Exothane 32, very low in color and viscosity, provides improved flexibility
Like many of Esstech’s other products, potential applications involving EXOTHANE™ Elastomers can vary across many industries from medical devices and nail gel enhancements to radiation-curable coatings.
