Application tips
l The bonded surface must be clean, dry and free of putty before bonding.
l Substrates that may seep out of oil are not suitable for direct application of sealant.
l For rusted or corroded metal surfaces (such as aluminum oxide, copper, iron oxide rust surface), in order to ensure the bonding effect, the rust on the surface layer needs to be worn off before coating.
l Due to the construction environment, construction methods, and material differences, pre-testing is required before use to ensure adhesion performance.
l The optimal coating temperature is +15 ~ +40°C. When the temperature is low, the extrusion resistance increases, warm up the adhesive before use.
