PRODUCT SPOTLIGHT: HEMA Succinate

Thursday, April 11th, 2013
Share This Post!

Item Code:  X-753-0000

Product Name: Methacryloyloxyethyl SuccinateHEMA Succinate
CAS#: 20882-04-6

EC No: 244-096-4
INCI: HEMA Succinate

SYNONYMS:  mono-2-(Methacryloyloxy)ethyl Succinate, 4-(2-(methacryloyloxy)ethoxy)-4-oxobutanoic acid

HEMA succinate is a carboxylic acid-containing methacrylate that functions as an adhesion promoter in a variety of applications.  X-753-0000 demonstrates an affinity toward bonding with aluminum, cold rolled steel, stainless steel and tin-free steel when cured “neat” or when formulated with one of our urethane acrylates such as EXOTHANE 108.

HEMA succinate’s low viscosity makes it an an easy to incorporate and reactive diluent.  Its’ monomethacrylate functionality allows it to promote adhesion in soak-off or temporary systems while improving “removability”.

High-Purity Adhesive Monomers

Friday, March 9th, 2012
Share This Post!

Manufacturing quality adhesive components requires raw materials of uncompromising purity. Their multiple applications place a considerable burden on their performance. The challenge is further heightened by the difficulty in synthesizing these molecules. These unique materials are capable of bridging the gap between hydrophilic and hydrophobic substrates.

 

X-863-0050:  NTG-GMA Sodium Salt

  • CAS # 133736-31-9

The sodium salt of N-tolylglycine glycidyl methacrylate is an adhesive that bridges the gap between hydrophobic and hydrophilic substrates. Na Salt of NTG-GMA is TSCA listed and can be solubilized in acetone.

X-863-0070: NTG-GMA Magnesium Salt

  • CAS # 211810-95-6

The Magnesium Salt of this surface active monomer (NTG-GMA) offers double the functionality as the sodium salt of NTG-GMA along with improved color.

The sodium salt and magnesium salt of NTG-GMA are both adhesion promoting monomers that also function as a co-initiators due to their tertiary aromatic amine group.

X-865-0000:  PMDM

  • CAS # 51156-91-3

Pyromellitic Dimethacrylate has the ability to bond to various substrates when used alone or in conjunction with our Sodium or Magnesium NTG-GMA salts. Bis(2-Methacryloyloxyethyl) Pyromellitate is TSCA listed and promotes adhesion between metal and plastic substrates in anaerobic adhesives.

X-830-0100:  PMGDM

  • CAS # 148019-46-9

Pyromellitic glycerol dimethacrylate is now available without any diluent.  To use this neat material, simply add the desired quantity into the diluent of your choosing or directly into your formulation.  PMGDM, also known as Bis (Glyceryl Dimethacrylate) Pyromellitate, can make an ideal adhesive system using its’ four methacrylate groups and two carboxylic acid groups to bond to various substrates.

PMGDM Patented as Adhesion Promoter in Nail Systems

Monday, November 8th, 2010

METHOD OF PROMOTING ADHESION TO KERATINACEOUS SURFACE, USE OF SAME IN RESHAPING SURFACE, AND KIT THEREFOR

Inventors: George F. Cowperthwaite, Coatesville; Allen D. Johnston, West Chester, both of Pa.; Susan C. Sheariss, Swedesboro, N.J.

Assignee: Esschem, Inc., Linwood, Pa.
Appl. No.: 09/061,948

INVENTION

This invention relates to a method for improving the adhesion of monomeric and/or polymeric materials to keratinaceous substrates which substrates contain a major amount of alpha-keratin. An aspect of this invention relates to methods for reshaping essentially rigid keratinaceous surfaces such as nail plates wherein adhesion of the reshaping material is improved through the use of an adhesion promoting treatment. Still another aspect of this invention relates to a kit for nail reshaping (e.g. nail extension) which includes an adhesion-promoting composition.

A method for improving-with an adhesion-promoting composition-adhesion of a synthetic monomeric or polymeric material (such as a curable acrylic monomer/polymerized acrylic system) to a keratinaceous substrate, as in, for example, the reshaping of fingernails or toenails. The adhesion-promoting composition comprises (A) an organic, dipolar, aprotic liquid carrier and, uniformly distributed throughout said liquid carrier, (B) pyromellitic dianhydride glycerol dimethacrylate adduct (“PMGDM”). The PMGDM
isomer mixture which typically results when pyromellitic dianhydride is reacted with glycerol dimethacrylate is preferred, particularly in view of its high solubility in solvents of relatively low toxicity (e.g. lower aliphatic
ketones). The adhesion-promoting composition can, if desired, be included in a nail-reshaping kit containing the materials and implements needed to reshape the nail plate.
