RTI docking is carried out in two ways:
- by gluing (fig. 1);
- end-to-end vulcanization (Fig. 2).
A special adhesive is used for gluing silicone products in a closed loop. It is applied to a section of a dry, non-greasy surface. If it is necessary to improve the adhesive characteristics, use
an adhesion primer.
The surfaces to be bonded are docked together and held in this position until they reach the desired height.
required functional strength. The adhesive cures with air moisture at room temperature.
The time of formation of the surface film is 10-90 minutes, complete drying of the adhesive occurs in 12-72 hours
(depending on the brand).
End-to-end vulcanization is performed in a mold heated to the required temperature. Rubber compound is applied
on a cut of a dry, non-greasy surface. The ends of the profile are joined together
and are kept in the mold until the rubber mixture is completely vulcanized (10-30 minutes).
In each individual case, preliminary tests are recommended to assess the adhesive strength.
The service life of a docked RTI may be negatively affected by the following factors::
