General:            ELV-2003 is a low cost, low viscosity modified liquid epoxy resin based on Bisphenol A. ELV-2003 is characterized by minimal handling hazards and very slight odor.  When used with amine       hardeners, such as ECA-032 or ECA-342, compositions based on ELV-2003 demonstrate excellent physical properties, adhesion, appearance and surface properties.

 

 

Applications:             * Casting

* Electrical

* Laminating

* Tooling

* Flooring

* Coating

* Impregnation

 

Advantages:                  ELV-2003 Is Especially Good for Applications Where Low Viscosity Is Necessary for Good Impregnation or Maximum Filler Loading or Where Reduced Odor and Diminished Toxicity Is   Required.

Formulating/mixing:        Formulations Based on ELV-2003 Can Be Easily Mixed at Room Temperature.  The Low Viscosity of the Resin Permits Easy Incorporation of Hardeners, Modifiers and Fillers.

 ELV-2003 Can Be Easily Blended with EMV-0040 or EHV-0050 at Different Ratios to Achieve a Higher Viscosity.

Handling/safety Precautions:

 The Following Basic Rules must Be Followed When Working with All Epoxy Products:

Avoid Contact with Eyes or Skin.

Avoid Inhalation of Dust or Vapors.

Wear Impervious Gloves and Splashproof Goggles.

Wash Hands, Arms and Face with Soap (Non-alkaline) and Lukewarm Water at Regular Intervals, Followed by Thoroughly Drying with a Paper Towel or Any Other Clean Towel.

Good Mechanical Ventilation of the Workrooms and Storage Rooms, as Well as Local Exhaust/suction Hoods for Workbenches, Is Necessary.

For Respiratory Protection, Use Niosh Approved Respirators.

 First Aid:

 For Skin Contact, Wash Immediately with Soap and Lukewarm Water, or with a Suitable Non-solvent Hand Cleaner.  Do Not Use a Cleaning Rag or Solvent for this Purpose.

For Eye Contact, Flush with Water for at Least 15 Minutes and Consult a Physician.

For Inhalation, Remove Individual to Fresh Air.
