Silicone Adhesives & Sealants
Advantages
- special one-component adhesives that adhere to silicone surfaces
- easy processing
- ideal for almost all sealing, bonding and coating applications in the fields of
- typical applications: automotive – construction – electrical engineering – electronics – healthcare – textiles – household appliances
Conventional organic adhesives do not adhere to silicone surfaces. WACKER’s special ELASTOSIL silicone adhesives are very easy to process and achieve excellent adhesion and bond strength. These one-component adhesives cure automatically at room temperature under the influence of atmospheric moisture.
Depending on the product, they release different by-products during the reaction:
- ELASTOSIL A grades release a basic amine compound
- ELASTOSIL E grades release acetic acid
- ELASTOSIL N grades release a pH-neutral alcohol or oxime compound
SEMICOSIL is a highly specialized brand developed for the electronics industry. All SEMICOSIL products are heat-curing, enabling faster processing (production) and controlled curing.
The SILPURAN product line is perfectly suited for use in medical technology and the pharmaceutical industry thanks to its outstanding properties – sterilizable and with excellent chemical and physical resistance, without any additional stabilizers.
