1. Mixing the two components
- The similar viscosity of SILBIONE TCS 7561 A and SILBIONE TCS 7602 C enables quick and easy mixing thanks to static mixers. It is always preferable to manual mixing to prevent bubbles and voids formation.
- The curing reaction can be inhibited by contact with certain materials containing metal salts (tin for example), amines or sulphur. A preliminary test is always recommended.

2. Curing and processing recommendations
- Application can be carried out either manually or, in case of larger quantities, using automatic dispensing equipment.
- SILBIONE TCS 7561 A +TCS 7602 C is generally applied through a nozzle, but it can also be coated by knife.
- It is recommended to apply SILBIONE TCS 7561 A + TCS 7602 C on clean and dry surfaces.
- The blend SILBIONE TCS 7561 A + TCS 7602 C starts curing even in confined spaces as soon as the two parts are mixed. When exposed to temperature, cure rate increases and the material should be completely crosslinked after a few minutes at relatively high temperature.
For example, for a 1mm thick layer of SILBIONE TCS 7561A + TCS 7602 C :
Curing time as a function of the temperature (approx.)
3 to 5 minutes at 90°C
2 minutes at 110°C
1 minute at 130°C
- When packaging has been opened, material must be used rapidly and/or resealed properly when stored to avoid potential inhibition or pollution of the two parts that could lead to lower performance or possible yellowing of the catalyst part.
|SILBIONE TCS 7561 A may be stored at a temperature below 40°C / 104°F for up to 6 months from its date of manufacturing.||Please consult the Safety Data Sheet of this product.|
SILBIONE TCS 7561 A
SILBIONE TCS 7561 A associated with SILBIONE TCS 7602 C is a two-component heat curing liquid silicone elastomer which cures by a polyaddition reaction.
Thanks to its extremely low softness and low modulus, this product is ideally suited for application on fabrics and bands used in undergarments and lingerie, as well as fabrics for medical applications, providing excellent non-slip characteristics without tension on the skin.
All products from the Textile Coating Silicone product line are specially engineered for textile coating applications.
