4.Characteristics
①Normally PU resin content 55-65%, more bigger and good performance wrinkle finish depends on higher resin content.
②Polyurethane (hydroxyl value 35±5) combine with curing agent T-1174 chemical ratio is 94/6;curing gent T-1530 IS 83/17;1% T-1530 replace of T-1174 could be used to enlarge the texture and increase the gloss of the film
③2-4% epoxy resin can be used to enlarge the texture and reduce the gloss of film.
