Résumé : |
To provide building materials with an elastic bond or seal, particularly flexible and elastic sealing compounds are needed. Now silane-terminated polymers are available for the first time with which such sealants and adhesives can be produced in the highest quality - even without plasticizers. |

- Low modulus - ideal for sensitive substrates
- Silane-terminated polymers
- Versatile and easily mixable
- High elasticity low modulus
- Expansion joints and windows
- Binder for universally applicable adhesives
- Fig. 1 : In construction engineering, joints are often found between components with sensitive substrates that are prone to erode and detach from the surface
- Fig. 2 : When building components meet, they inevitably form a joint. For the joint to remain permanently sealed, the sealant must be able to accommodate the changes in joint dimensions again and again without tearing or detaching from the surface
- Fig. 3 : GENIOSIL XM 25 yields low-modulus sealants with exceptionally high elastic recovery
- Fig. 4 : Tests show that GENIOSIL XM 25 yields low-modulus sealants with reliable adhesion to a wide range of substrates
- Fig. 5 : Tests show that sealants formulated with GENIOSIL XM 25 have a longer skin over time (SOT) (upper chart) and a lower modulus than comparable products (lower chart). This provides better protection for vulnerable joint faces, for example of prefabricated concrete parts or window frames
- Fig. 6 : Weathering tests show that sealants based on GENIOSIL XM 25 retain their elasticity for years. The test samples were manufactured according to DIN 150 7389 and were stretched twice their original length
- Fig. 7 : GENIOSIL XM 25 was developed for stressed expansion and connection joints. A typical application are expansion joints in buildings made of industrially prefabricated concrete parts, which are built in large numbers all over the world |
