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.

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.

Hydrogen bonding interactions in methacrylate monomers and polymers

ABSTRACT
It is well appreciated that hydrogen bonding affects a variety of monomer and polymer properties. This study focused on Bis-GMA and urethane dimethacrylate (UDMA) to help elucidate how the strength and nature of
specific noncovalent interactions involved with these different functional dimethacrylate structures are expressed in the monomers and polymers. Hydrogen bonding interactions in monomers and comonomer mixtures as well as in appropriate model compounds were examined by FT-IR under ambient conditions, at elevated temperatures and in dilution studies. The investigation of hydrogen bonding extended to monomer viscosity, photopolymerization reaction kinetics, and polymer mechanical properties.
CONCLUSION
The strength of hydrogen bonding was shown not only to be greater for Bis-GMA compared with UDMA, but there is also greater contribution from intermolecular interactions that enhance the hydrogen bonding effects. While UDMA-based polymers reach significantly higher levels of conversion compared with Bis-GMA materials, the stronger hydrogen bonding reinforcement associated with Bis-GMA appears to provide for comparable mechanical strength properties. Depending on the hydrogen bond donor functionality of a monomer as well as its neighboring functional groups, overall monomer structure and comonomers used, hydrogen bonding can favorably affect polymerization reactivity and mechanical properties, even in materials that form highly crosslinked polymeric networks.

TECHNICAL BULLETIN: Refractive Index of Monomers and Their Respective Polymers
The refractive index (RI) of photopolymers is an essential property for many applications. For optical and coating applications, the RI can be related to the resultant gloss or clarity upon cure. Within the dental industry, the refractive index of the organic polymer matrix, must match that of the inorganic filler and substrate in order to avoid obvious “lines” where the product is applied.
Various factors affect refractive index values. The presence of conjugated ring structures contributes to increasing RI. In general, larger molecular weight monomers have a tendency to possess a higher RI in comparison to their lower molecular weight counterparts. Similar to this trend, high molecular weight functional groups like methacrylates have higher RI than their acrylate counterparts. Higher atomic weight atoms also seem to be predisposed to having higher RI.
Recognizing the importance of refractive index to our customers, Esstech has assembled RI data for a portion of our existing monomer products as well as their corresponding homopolymers.

Maintaining its position as an industry innovator, Esstech has also created functional, high refractive index materials. Contact us to learn more about these novel materials and how Esstech can make a material to match your application.
