SEAL PRIME (PC-2125) is a colourless to light yellow, 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 groove, bricks, etc, of joints to reduce surface, porosity and avoid pin holing and bubbling in polysulphide-based joint sealant system
