SEAL PRIME (PC 2125) is a colourless, solvent-based, liquid primer composed of Silane resins, which has been specially designed for use as primer in order to ensure and enhance a perfect adhesion between the substrate and the polysulphide-based sealant. It is not recommended for application of sealants in areas where sealant remains in completely immersed in water.
AREA OF APPLICATION:
• Primer for polysulphide-based joint sealants subjected to both stresses and movements or cyclical condition
• Treatment for porous surface, such as concrete, bricks, etc, of joints to reduce surface, porosity and avoid pin holing and bubbling in polysulphide-based joint sealant system
