LUWIPAL 073
LUWIPAL 073
The properties of this methanol-etherified partially alkylated resin compare to those of LUWIPAL® 072. The only difference is that LUWIPAL 073 is an aqueous solution.
It is particularly suited as a crosslinker for water-thinnable finishes based on alkyd, acrylic or saturated polyester resins or polymer dispersions.
LUWIPAL 073 is highly reactive in baking. It already crosslinks after 20 – 30 minutes at 110 – 120°C (230 – 248°F).
