Description

[Arakawa Chemical, Japan] A brand name for a low molecular weight resin developed for use as a tackifier. Arkon P-90 is a saturated alicyclic hydrocarbon with an average molecular weight of 630. It forms a colorless, high gloss film. It is resistant to weathering and heat but does oxidize and become less soluble with time (van Vooren 1998).

  • Soluble in petroleum hydrocarbons and turpentine. Insoluble in water, ethanol, acetone.
  • Softening point = 90 C
Density 0.991
Molecular Weight Tg =35.6 C
