Connection with One-Sided Coating

If the components can be briefly exposed to a temperature of 200°C, the connection can also be made with a one-sided coating. The KlettSintering achieves similar tensile and shear strengths as the KlettWelding. Especially if one of the two joining partners can only be coated in a complex process, this process offers clear advantages.

KlettSintering Tape

The KlettSintering Tape can be used to avoid having to coat either of the two joining partners. As with double-sided adhesive tape, a metal foil coated on both sides is inserted between the two components. By simply pressing together, a double Velcro sintering process takes place at 200°C. The two-sided adhesive tape is then inserted between the two components.
