USE
Manufacturer: Hitachi Chemical, Cytec/Solvay Group
Outstanding properties: low volatility, low viscosity; provides outstanding wet adhesion and wet
scrub resistance at levels as low as 0.5% (phm). Does not homopolymerize easily during emulsion
polymerization
Recommended for resins: acrylics
Recommended for products: UV adhesives, interior and exterior architectural coatings
Recommended applications: provides flexibility, good adhesion to metal and good compatibility
with other materials; outstanding wet adhesion and scrub resistance for acrylic, vinyl-acrylic, sty-
rene-acrylic and vinyl-VEOVA polymers. Imparts excellent stability against homo-polymerization.
Designed for the interior and exterior architectural coatings market for wet for high humidity con-
ditions.
