areas of application
BORNIT® Hot Sealing N1 is used to seal joints in areas of concrete and asphalt surfaces non-traversed by traffic, which absorb high levels of movement, e.g., in the curb area of bridge structures. BORNIT® Hot Sealing N1 is designed for a possible change in the joint gap width of up to 35 %.

type and properties
BORNIT® Hot Sealing N1 is a meltable, hot-processable sealing compound based on polymer bitumen, mineral fillers and organic additives.
BORNIT® Hot Sealing N1 provides high elasticity and ductility, good adhesion on the joint flanks and high heat and cold resistance. The sealing compound is impermeable to water, resistant to aging and insensitive to water and de-icing salts. Its low density results in reduced material consumption in relation to the filling volume.
Quality according to DIN EN 14 188-1, joint sealants type N1.

  • high absorption of movement
  • good adhesion to the joint flanks
  • insensitive to water and de-icing salts

The joints must be dry and clean. Any oil and grease residues as well as loose particles must be removed. The joints must be blown out with compressed air.

Prior to pouring, the fusion faces must be primed with BORNIT® Hot Compound Primer or BORNIT® Hot Compound Primer Spray, resp., in order to achieve the required flank adhesion. It is recommended to prime approx. 1 cm of the road surface on both sides of the joint as well, in order to guarantee adhesion up to the upper edge. Prior to starting pouring, the primer must have dried off (finger test). First, peel off the packaging from the sealing compound. Then slowly heat BORNIT® Hot Sealing N1 to the processing temperature in a sealant heater equipped with stirrer, thermostat-controlled burner and thermometer. In that, the maximum melting temperature of +180 °C must not be exceeded and the sealing compound must be kept moving, in order to avoid local overheating and settling of the fillers. Only melt the anticipated amount needed for the day, since repeated heating could have a negative effect on the material properties. Perform pouring with suitable equipment (mechanically or manually, e.g., with a slim pouring can with an elongated spout, etc.). Stop application when it starts to rain! Since a volume reduction occurs with all sealing compounds after cooling, application should be undertaken in two layers. In that, the second layer is to be applied immediately after cooling of the first one, onto the still shining, clean surface. In that, the processing temperature must not be undercut, in order to guarantee homogenous fusion. For concrete and asphalt traffic areas, BORNIT® Hot Sealing N1 must be poured such that a trough-shaped depression of min. 1 mm to max. 6 mm (with chamfered joint edges) is formed beneath the road surface. Protrusions or excessive pouring, resp., must be avoided in any case.

approx. 1.0 kg / litre of joint contents.
The consumption of BORNIT® Hot Compound Primer amounts to approx. 4 % of the sealing compound quantity.
