Description
Sikaflex primers are special materials formulated to improve the bond of Sikaflex urethane sealants when applied to specific substrates.
Sikaflex Primer 449 is used to promote adhesion to pvc, solvent-based enamel, PPG’s fluorocarbon Duranar-finish, and certain plastics such as ABS and Plexiglass. Most substrates require a primer only if testing shows need for it or where the sealant will be underwater after cure.
Certain substrates do require a primer under all conditions.
Single-component, ready to use.
Easily applied by brush, dauber, or spray.
