Film strength, hairiness control and easy hot-water desizing.
Compare these gradesSeed liquor at 3–6%, even particle size, less wall build-up.
Compare these gradesDry film re-activates in cold water; release layer controls curl.
Compare these gradesOpen time, crack resistance and water retention in dry mix.
Compare these gradesPartially hydrolysed: cold dispersion, stronger surface activity.
Compare these gradesFully hydrolysed: hot water, denser film, water and solvent resistance.
Compare these gradesTwo questions settle most inquiries: is the make-down hot or cold, and does the film need to resist water? Everything else follows.
