Regalrez 1094 is fully hydrogenated ultra-clear hydrocarbon resin with low molecular weight exceptionally resistant to ageing, oxidation and suggested for use where clarity, resistance to yellowing and excellent UV stability is a requirement.  Easily soluble in aromatic solvents; diluted to 20-30%, is ideal for preparation of final or reversible retouching varnish. Small molecules ensures uniform distribution, excellent adhesion and low viscosity of varnish.
