Boss PU25 Urethane Sealant
BOSS PU25 is a single component polyurethane based elastomeric sealant which cures under the effect of atmospheric humidity to form a highly elastic, tear- and weather-resistant joint.
AREAS OF APPLICATION
BOSS PU25 can be used to bond various building materials and for expansion joints.
BOSS PU25 has a good adhesion without primer on most current materials: wood, aluminium, most lacquered metals, concrete, stone, ceramic tile
INSTRUCTIONS FOR USE
The substrates must be clean, even, dry, free of dust, oil, grease and any contaminants that could harm bonding. If they need to be cleaned, clean them with methylethylketone (MEK), acetone or grease remover. Apply a primer if necessary.
When using solvents, extinguish all sources of ignition and carefully follow the safety and handling instructions given by the manufacturer or supplier.
