PVP/VA™ E-635 pvp/va is a copolymer with excellent adhesive, cohesive, and binding properties for many substrates and active ingredients. This product's films are oxygen permeable with good water-holding properties, which makes it appropriate for seed coating and leaf-adhesion. It also provides excellent survivability of biological materials and organisms such as rhizobia. Due the molecular weight, PVP:VA ratio, and HLB relationship, PVP/VA™ E-635 pvp/va copolymer is more soluble in water-based formulations.
