Borchers® VP 0132 (Trial Product) 14
Primary drier for solvent borne oxidatively drying coatings with enhanced drying activity
Description
Borchers® VP 0132 is a new primary drier based on an organically modified Vanadium compound. It is suitable either for clearcoats or for pigmented solvent borne oxidatively drying coating systems. Borchers® VP 0132 should replace other established primary driers, especially cobalt siccatives.
Properties
Borchers® VP 0132 provides rapid surface dry and also good through-drying properties. The drying ability of coatings siccativated with Borchers® VP 0132 remains constant even after extended time of storage. The drying results are comparable to those obtained with cobalt siccativated systems.
Applications
Borchers® VP 0132 is suitable for all solvent borne coatings as well as VOC-reduced and high-solid paints based on alkyd resins, epoxy esters and other oxidatively drying binders. The characteristics remain constant whether using clearcoats or pigmented systems. The possibility to use Borchers® VP 0132 in waterbased paints has to be determined empirically.
Mixing and Addition Rate
Borchers® VP 0132 can be added to the paint system in any formulation step. We recommend its addition after the dispersing process prior to adding an anti-skinning additive. A dilution with water or any organic solvent is not suggested.
The required amount of Borchers® VP 0132 depends on type and quantity of the used binder. Usual amounts are approx. 0,02 to 0,06 % Vanadium by weight based on solid binder. It is recommended to adjust the quantity on the amount of substituted cobalt. Due to the higher drying activity of Borchers® VP 0132 it is proposed to start with half the addition rate of substituted cobalt, related to the metal content. Usually a further optimization is necessary.
The additional application of Octa-Soligen® secondary driers may result in improved through-drying efficiency and reduced film yellowing due to synergistically effects. The through drying process can be improved particularly by adding Octa-Soligen® Strontium, Octa-Soligen® Zinc or Octa-Soligen® Zirconium driers. To improve yellowing resistance in white pigmented coatings we recommend the use of Octa-Soligen® Strontium and Octa-Soligen® Calcium driers. The latter also provides drying stability in pigmented systems.
