Reliable in the choice of products, in processing, but just as reliable in the result! With our products and processing options, you always achieve a reliable result that not onlyensures thelongevity of the window , but also stands for perfect quality . Furthermore, we accompany you together step by step to the RC examination.
There are different types of quality control, depending on the objective of the test.
Aim of the test:
The correct mixing ratio or the correct curing speed is checked by determining the pot life.
Implementation:
Apply mixed 2-component silicone to a PE film or glass. Use a spatula to "spread" the paste. The paste is soft at first and becomes increasingly tough as it begins to harden. When the paste resets, the end of the pot life has been reached. As the pot life is influenced by the ambient temperature and humidity, among other things, fluctuations can occur here.
Aim of the test:
This test serves to ensure the perfect homogeneity of the mixture.
Implementation:
For the glass plate test, apply a small amount of the mixed adhesive to a clean glass (dimensions approx. 10 x 10 cm). Then place a second piece of glass on top and press the two glasses together. The adhesive between the glasses must be of a uniform, homogeneous colour. When processing from side-by-side cartridges, fine white streaks are tolerable.
Aim of the test:
This test serves to ensure the perfect homogeneity of the mixture.
Implementation:
A small amount of the mixed adhesive is applied to a white sheet of paper or PE film, the paper/film is folded, pressed smooth and then unfolded. As with the glass plate test, check the mixture for streaks or smears.
*Pursuant to ISO 21194:2019
Aim of the test:
The peel test checks the correct adhesion of the adhesive to the substrates to be bonded.
Implementation:
Apply an approx. 10 x 10 mm wide or thick adhesive strip to each of the substrates pre-treated according to the specifications in the technical data sheet of the 2-component adhesive. The length of the adhesive strip is 10 cm. After a curing time of 24 hours, cut the adhesive on one side with a knife and try to pull the adhesive off the substrate by hand at an angle of >90°. The test must be carried out for both substrates.
In addition to our products, our extensive services complete our package of services. That is why we also offer services and additional benefits in the area of bonded windows: We accompany you step by step to the RC test. Benefit from our many years of experience in the window industry: We are optimally networked with all known hardware manufacturers, window system providers and also the testing institutes.
The first step to your tested RC system is precisely ascertaining your requirements. Here, it is not only a question of which RC class you want to achieve, but also which window system you are working on, which hardware you are using, which surface finish is used and how you want to apply the bonding technology.
After your requirements have been clearly ascertained and the coordination with all parties involved has produced the best possible result, we put it into practice. We accompany you during the production of your test specimens and bond them with you. Here we discuss step by step what is important in RC bonding. We explain how quality control works and how OTTO adhesives are best handled.
The next step is to go to the testing institute. Here your elements are tested and classified according to EN 1627 requirements and classification of burglar-resistant building components. First, the static strengthis tested according to EN 1628. For this purpose, precisely defined points of the test specimen are subjected to a static test load. Next, the dynamic load test is carried out in accordance with EN 1629. Finally, the manual attack on the test specimenis carried out according to EN 1630, in which the available tools and the time count: Depending on how long the test specimen withstands which tool, the burglar resistance is classified in RC classes 2, 3 or 4.
