More About Silane Based Glues
Modified silanes adhesives were created in the 1980’s in Japan. The modified silane based glues have elastic adhesives in comparison to the traditional polyurethane adhesives. Modified silane based adhesives are popular in both Europe and American Markets.
Modified silane based adhesives are a one-component glue that cures with the action of moisture. During its curing process by polycondensation, this type of adhesive emits methanol and once cured acquire elastic properties and typical strength of an elastomeric material.
Dependant of the resin composition or chemical backbone of the adhesive there are two variants of modified silane glues:
- Polyether modified silanes
- Polyurethane modified silanes
The polyether-modified silanes are more resistant and more elastic than polyurethane-modified silanes. Polyurethane-modified silanes are also called hybrid polyurethanes.
Typical properties of modified silanes adhesives
- Are elastic and flexible material
- Tensile strength between 1 and 4 MPa, the silane-modified based epoxy can reach 8 Mpa.
- Maximum elongation of 100% to 300%.
- Excellent resistance to ultraviolet rays
- They can be painted, even shortly after applying (wet on wet).
- Adhere to a wide range of materials (metal, ceramic, and plastic) without primers or activators.
- Do not contain isocyanates, reducing health risks
