SYNOLAC 435 BA 70
Product overview
SYNOLAC 435 BA 70 is a semi-drying, medium-oil alkyd for nitrocellulose combination varnishes, acid curing paints and 2 K-polyurethane systems for wood coatings.SYNOLAC 435 BA 70 is particularly recommended for use in nitrocellulose varnishes with comparatively good film build for industrial furniture finishing.SYNOLAC 435 BA 70 provides an excellent plasticizing effect for nitrocellulose. In relevant formulations it achieves high gloss levels and a good balance of flexibility and hardness allowing the formulation of varnishes with increased levels of alkyd resin and thus improved film build.In acid curing systems SYNOLAC 435 BA 70 shows a good reactivity and provides a good flexibility even at low temperatures. Stoving systems based on SYNOLAC 435 BA 70 also maintain a good balance of hardness and flexibility and show a good gloss retention in exterior applications.
