detailed information

Uses    
BORNIT® Hot Sealing Rail is a bituminous, polymer modified rail sealing compound in accordance with TLbit Fug 82 for the filling of joints between rails and adjoining surfaces as paving, concrete or asphalt.

Properties    
BORNIT® Hot Sealing Rail fulfils the requirements of ”the Technical Delivery Conditions for bituminous joint sealants“ (TLbitFug 82), of “rail sealants”.
BORNIT® Hot Sealing Rail distinguish itself by the following characteristics:
•    plastic elastic set, therefore optimum balance between high movement
     accommodation and stress relief within the joint
•    good application characteristics at heat and at cold
•    good bonding at rail and adjoining surfaces
•    high ageing resistance of the joint
•    resistant against aqueous solutions, salts and thinned acids, or similar
•    bituminous building material and therefore problem-free recyclable

Technical Data    
Application temperature:    approx. 160 – 180 °C
Density:    approx. 1,38 g/cm3

Application    
a)  Melting:
BORNIT® Hot Sealing Rail has to be heated carefully to the application temperature of 160 - 180 °C in a boiler equipped with mechanical agitation, indirect heating and thermometer. The temperature of the sealant must be thermostatically regulated; it must be controllable at all times. Overheating of the sealant should necessarily be avoided, as this will damage the polymers, which were added for the improvement of the product, and consequently it will lead to a loss of the guaranteed properties.
b) Requirements to the subsoil:
The rail joints to be sealed should be thoroughly blown with high-pressure-air or cleaned with a brushing machine, whereas you have to pay attention to special separation of cleaning and application works. For artificial dry-out or pre-heating of the joints, hot compressed air lances can be used. The rail flanks have to be prepared by removing loose rust particles with the help of sand blasting or equivalent. For BORNIT® Hot Sealing Rail the primer BORNIT® Hot Compound Primer has to be used, which is adapted to this material. The function of the primer is to bind the dust and to form an adhesive layer which will fuse with the sealant being filled into the joints. At the same time the primer also forms a rust protection for the pre¬treated rail. The primer must cover the joint flanks completely by forming a film. Before filling the joints the applied primer must have dried, i. e. the surface must be touch-dry.
c) Filling of the joints:
The joint sealant can be applied by can or mechanical by the help of an application lance. The joint sealant must have reached the indicated application temperature during pouring work. If the pouring temperature is clearly below the stated temperature, the flow ability of the sealant suffers. The joint sealants may possibly not fill the to be poured joints completely. There is the danger that voids may occur which later can result in sinking of the sealant under rolling traffic. To prevent a sinking of the rail joint compound the cell filling has always to be stable. The cooling of the sealant may cause shrinkage dependent on the joint dimensions; a second pouring can be necessary. This second pouring should be made immediately after the first one. The joint sealant has to be built-in at least 3 mm deeper of the upper edge of the head of the rail.

Consumption    
Approx. 1,3 kg of the sealing compound for each litre of joint volume.

Primer: The consumption of the primer (BORNIT® Hot Compound Primer) is approx. 3 % of the sealant amount needed.

Storage    
The product’s storage period is 12 months.
It is necessary to protect the cardboxes from moisture and direct sunlight.
