Description

BOSS® 335 is a ready-to-use, single component, self-expanding polyurethane adhesive for clean, efficient and economical permanent bonding of insulation panels and plasterboard in building and construction.

Properties

• Cuts working time by up to 30%.
• Excellent initial bond, even at low temperatures.
• Economical in use due to precise application.
• One can covers up to 14 m² of insulation.
• Suitable for vertical applications.
• Can be applied at temperatures between -5 °C and +35 °C.
• Thermal conductivity 0.035 W/m.K enhances performance of insulation panels when filling gaps.
• Remains flexible, does not become brittle.
• Levels uneven surfaces.
• Limited post expansion for fast and precise installation of insulation panels and plasterboard.
• Substantial space and weight savings compared to conventional PU roof adhesives, bonding mortars, etc.
• Fast curing, work can continue about 1 hour after application.
• Solvent-free.
• Resistant to a variety of solvents, paints and chemicals.
• Does not age or rot, mould and mildew resistant, but not UV resistant.
• Water resistant (not watertight).
• Building material class B1 according to DIN 4102-1.

Applications

• Clean, efficient and economical permanent bonding of insulation panels.
• Suitable for bonding polystyrene (EPS + XPS), polyurethane (PUR/PIR) and phenol resin foam based insulation panels for flat roofs, perimeters, facades, insulation/drain elements, cellar ceilings, internal insulation, etc.
• Suitable for bonding gypsum plasterboard/gypsum fiberboard in dry lining applications.
• Suitable for bonding non-load bearing walls, e.g. partition walls, screen walls, cellar bars, stone shelves, etc., of concrete precision blocks (aerated concrete, sand-lime brick, gypsum, hollow bricks…).
• Fills cavities between individual thermal insulation panels.
