Vapour Pressure 20°C, 1.8mm (calc)
Specific Gravity 0.92
Flashpoint 54°C
Solubility in Water 0.1 - 1%

% Volatiles by Volume 100

Uses :

  • As a "Catalyst" or "Accelerator" which acts as an end-to-end linking agent.
  • Epoxy Resin Accelerator.
  • For better penetration and stability BDMA is recommended in place of the DMP-30.
  • The quantity of BDMA which is required is 1-1.2 ml.Slight variations of the accelerator (DMP-30 or BDMA) will drastically affect the color and brittleness of the block.
  • It is desirable that only the minimum amount of accelerator (BDMA) be used, and should be added just prior to actual use of the resin mixture. A plastic mixture to which accelerator has been added cannot be kept unrefrigerated for more than several hours before it begins to polymerize.

Health Hazard Information :

  • Eye Severe eye irritant. Vapours are highly irritating to eyes. Liquid may cause permanent eye damage.
  • Skin Severe skin irritant. Vapours are highly irritating to skin. Skin exposure to laboratory rabbits produced tremors and excitement.
  • IInhaled Vapours are highly irritating to lungs and upper respiratory tract.
  • Chronic Conjunctivitis in the eyes can result from overexposure. Dermatitis of the skin can result from overexposure.

Safe Handling Information :

  • Storage And Transport
    • Keep container tightly closed. Store in a cool, dry, well-ventilated, flammable liquid storage area or cabinet.
