APPLICATIONS
LEICRIL AP 3381 is used in combination with other
externally crosslinked acrylic resins in order to
improve the initial drying and the hardness of the
paint. LEICRIL AP 3381 can also be used alone and
crosslinked with aliphatic isocianates like Desmodur N.
Particularly important is the possibility to dilute the
paints with white spirit.
In two component products for every 100 parts of LEICRIL
AP 3381 are necessary ca 14 parts of Desmodur N .
