Repaschol 178 / Helmipren 14021 / Trellbond T2

following only mentioned as Repaschol!

Application

Repaschol is a two-component contact adhesive for joining and repairing conveyor belts, lining steel containers and applying rubber coating to rollers. Repaschol is approved for use in mines.

Properties

Joints made with Repaschol are temperature, plasticizer and moisture resistant. The pertinent values are dependant on the composition of the rubber compound and the stress to which the part is exposed.

Pre-conditions

The materials to be bonded must be dry and free from grease and dust. If necessary, they should be cleaned with solution 691.
Rubber surfaces have to be roughened. Since roughened surfaces lose part of their effectiveness during longer periods of storage, adhesive must be applied to roughened rubber surfaces right away.
In order to improve the adhesion of Repaschol to metal surfaces, it is recommended to apply a coat of steel primer first.

Instruction for use

Carefully mix Repaschol with the hardener.
 
The best adhesion to various rubber materials is achieved within 15-30 minutes after the mixture with the hardener. After this mixture has been stored for a longer period of time, its adhesion decreases to a certain extent.
 
The adhesive/hardener mixture is applied to the suitable prepared surface of the materials to be bonded by means of a brush or spatula. When bonding rubber to rubber, it is recommended to apply the adhesive twice, waiting at least 10 minutes after the first application for the adhesive to dry. When bonding textiles the adhesive has to be applied three times so as to achieve a good adhesion (in this case, too, at least 10 minutes should be allowed for drying of the adhesive after each application).
 
After the adhesive has been allowed to dry, the parts are bonded within the contact life of the adhesive by applying brief pressure with hammer or preferably with a press.
 
To avoid faulty bonding, the temperature of the room and the adhesive should not be allowed to drop below 15C.
