PS: Soft contrast is only the comparison between the three. Even 178, also more than acrylic resin, amino resin,

polyester resin, alkyd resin and some soft.

PS: Softsrar^TM  28^# product manual

Softsrar^TM  28^# is a adipic acid polydiol, completely linear soft resin.

(1) Solid content is about 99% without solvent.

(2) Relatively low viscosity

(3) Good solubility—Normal polydiol is insoluble with the most resin. But 28# resin has good solubility

(4) Good softness—used in amino PU epoxy paint to increase the toughness, and little effect on adhesion.
