  • auto-ignition temperature of 403 ° C;
  • flash point of -7 ° C;
  • boiling point of +59 ° C;
  • not freeze;
  • not gaining viscosity;
  • solvent density of 646 - 0.87 g / cm3.

In addition, there will be more than a glimpse into the passport of the solvent, although most figures do not tell the common man, but the technology in the production able to give advice or to prohibit the composition for use on the basis of these parameters.There, the solvent has the following characteristics:

  • mass fraction of water - 0.09%;
  • acid value - 0.06 mg KOH / g;
  • volatility in ethyl ether - 12;
  • number of coagulation - 40 y / o;
  • dissolving action - does not remain opaque and whitish spots;
  • specific weight of solvent 646 - 0.68 kg / l.

What is particularly important in the planning of production and formulation of safety, so that's what is solvent 646 hazard class.The figure for him is equal to 3, and also registered in the passport.
