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”.

Dental Photoinitiators

Friday, March 8th, 2013
Share This Post!

 

Simply described, photoinitiators are chemicals that generate radicals upon exposure to light.  A more complete description would include all the complexities inherent with the chemical nature of photoinitiators including type, concentration and absorptivity.  All of these factors must be taken into consideration when optimizing a light-curable formulation.

With PL Industries, the new division of Esstech Inc., we can now provide the monomers, adhesion promoters, oligomers, photoinitiators and technical expertise to guide you in your material selection.  The following is an example of our photoinitiator products.

 

PL-CQ
Camphorquinone
Absorption Range:  400-550 nm, 470 nm peak

Description:  Type II, fine yellow powder, very common and effective for dental restoratives, heat aids in dissolution

PL-TPO
2,4,6-Trimethylbenzoyl-diphenylphosphine oxide
Absorption Range: 230-430 nm, 385 nm peak

Description:  Type I, off-white, crystalline powder, dissolves in most monomers, exhibits photo-bleaching properties

PL-PPD
1-Phenyl 1,2-propanedione (PPD)
Absorption Range:  300-480 nm, 393 nm peak

Description:  Type II, yellow liquid, believed to have a lower rate of polymerization that is not detrimental to overall conversion

PL-EDB
Ethyl-4-dimethylamino benzoate
(EDAB, EDMAB)

Description:  a tertiary amine synergist typically used in combination with type II photoinitiators such as PL-CQ

X-866-0000
Dihydroxyethyl-para-toluidine
(DHEPT)

Description:  solid, off-white amine co-initiator that is low in color, requires melting or crushing to simplify incorporation

X-867-0000
2-dimethylaminoethyl methacrylate
(DMAEMA, MADAME)

Description:  a clear, colorless liquid used as an amine synergist for type II photoinitiators, commonly used in 1:2 ratio with CQ

Product Spotlight: “Solid” Urethanes

Wednesday, November 28th, 2012
Share This Post!

In our pursuit of new and innovative materials, Esstech has created an experimental line of “solid” urethanes.  These materials are solid at room temperature, resembling glass both in appearance and the ability to fracture easily into a powder upon impact.  Here are more of our initial observations:

  • Easy to incorporate into a powder coating once fractured.
  • Extrude well under normal conditions and can be ground, sieved or sprayed.
  • Create very clear and colorless coatings.
  • Cured materials have excellent solvent resistance, flexibility and adhesion to polycarbonate and ABS.

 

Esstech offers a multitude of monomers including acrylates, methacrylates, diluents, crosslinkers, oligomers and more!  Contact us to discuss sourcing of existing commercial products or custom development.

Product Spotlight: EXOTHANE ACRYLATES

Wednesday, September 12th, 2012
Share This Post!

EXOTHANE(tm) ELASTOMERS

Product Code: X-991-0000

Synonyms:  EXOTHANE 108

Exothane 108 is the acrylate analog of our Exothane 8.  It shares similar properties to Exothane 8 such as enhanced toughness, high percent elongation and good tensile strength but, cures much faster.

 

Product Code: X-992-0000

Synonyms:  EXOTHANE 126

Exothane 126 is the acrylate analog of Exothane 126.  When cured “neat”, Exothane 126 has very high conversion and very low shrinkage.  The resulting homopolymer is very soft and rubber-like.

 

We are constantly developing more Exothanes to meet your applications!  Email us to request samples or discuss custom synthesis, techsupport@esstechinc.com

BHT-INHIBITED MONOMERS

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)
