Scratch-resistant coatings from BASF

August 11, 2005

Patent No. 6,835,420 B1
BASF Coatings AG has received a
patent for a coating material curable
thermally and, if desired, with actinic
radiation. It is comprised of at least
one binder containing at least two
functional groups, and at least one
crosslinking agent containing at least
two functional groups, wherein the
functional groups of the binder are
able to undergo thermal crosslinking
reactions with complementary functional
groups in the crosslinking
agent, and the functional groups of
the crosslinking agent are able to
undergo thermal crosslinking reactions
with complementary functional
groups in the binder, and optionally
at least one constituent that is
crosslinkable with actinic radiation,
at least one photoinitiator, at least
one thermal crosslinking initiator, at
least one reactive diluent curable by
at least one with actinic radiation
and thermally, at least one coatings
additive, and at least one organic solvent,
wherein the at least one binder
contains in copolymerized form at
least one olefinically unsaturated
polysiloxane macromonomer containing
on average per molecule at least
three double bonds.
