Sikaflex 265 polyurethane sealant for glazing applications

      Description of the Sikaflex 265 polyurethane sealant for glazing

The Sikaflex 265 sealant is a single-component polyurethane sealant from the Sikaflex range by Sika. This high-performance product is used for the assembly of glazing in transport vehicles (such as buses, trains, or metros).

Its formulation provides resistance to UV and aging, making it ideal for outdoor applications exposed to the elements. It is easy to apply with good filling capabilities and allows for smooth finishing, which should be done before skin formation.

Its polymerization is relatively quick but can be accelerated by using Sika Booster Paste, which can be attached to the outlet of the packaging. The booster contains the necessary amount of water for curing, independent of the humidity in the air. For optimal results, the Sikaflex 265 should be slightly heated to a temperature of 60 °C. However, the curing speed may be affected by ambient temperature. The final characteristics of the adhesive after complete curing will not differ whether polymerization was induced by the booster paste or by ambient humidity.

Given these various characteristics, the Sikaflex 265 sealant can be used to create finishing joints where aesthetics are important, primarily due to its easy smoothing properties.

It is suitable for both manual and automated applications.
