Anti-blocking

 
ALTON AT 837
water-based additive free from ethoxylated nonylphenol, waxes and fats and paraffin specially designed for impregnated paper production. Excellent anti-blocking properties at low dosages. Dosing ALTON AT 837 (0,1-0,2 %) with UF resin in the impregnation bath, the UF resin migration to the paper surface is strongly reduced.
ALTON AT 839
mixture of up-to date polymers, prevents sheets from blocking caused by moisture absorption; when added into a resin, the surface properties, typically the oleo-hydro repellency, will be improved as effect of its cross-linking/ filming characteristics.
