[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).
