Tannin blocking primer, resin.
Cytec Industries Inc. has developed two new DUROXYN[R] tannin blocking products for the architectural wood coatings market. DUROXYN
VEF 2406 is a barrier primer and DUROXYN EF 2107 is a liquid coating
resin. These products feature a new technology for tannin blocking
coatings that do not require the use of reactive pigments. They are both
below 100 g/L VOC and reportedly still match or exceed performance
properties of conventional solvent-borne tannin blocking primers. For
