1. Mixing the two components

 

  • Some fillers may settle during transport and storage. To ensure a uniform mix, the components should be thoroughly stirred prior to use.

 

  • Use preferably static mixing equipment to prevent bubbles and voids formation. In case of hand mixing, degas the mix under vacuum 3-5 kPa before processing the product.

 

  • BLUESIL TCS 7550 A&B can be further additivated with pigments and fillers, please contact Elkem Silicones' technical support for more information.

 

  • 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

 

  • Curing of Bluesil TCS 7550 A&B takes place at a temperature between 100°C and 200°C. As an indication, the curing time at 150°C is approximately 5 minutes. Time and temperature depend on the thickness of the coating.

 

  • Bluesil TCS 7550 A&B can be applied by knife coating, transfer coating, screen printing...

 

  • Adhesion to substrate will depend upon the curing conditions. A preliminary test is recommended to determine optimum cure conditions, and a temperature ramp-up in industrial ovens is always preferred to avoid bubbles and ensure best adhesion.

 

  • When used as a glue between two coated or uncoated fabrics, the curing conditions could be 160°C for 3 min under 35 N/cm² pressure.

 

  • After use, packaging must be tightly closed and protected against moisture contamination to preserve its properties. When packaging has been opened, material should be used rapidly.

BLUESIL TCS 7550B may be stored at temperatures between -20°C / -4°F and 30°C / 86°F for up to 12 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.ELV;RoHS;WEEE
