BLUESIL TCS 7537 A and BLUESIL TCS 7537 B, was designed to exhibit excellent adhesion over time on difficult substrates, such as unscoured textiles.

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

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

•Low add-on weights (20 to 50 g/m²) can be achieved with typical knife coating processes, and material can sustain high coating speeds (20 – 60 m/min). BLUESIL TCS 7537 A is also suitable for laminating and transfer coating processes.

•TCS 7537 can be further additivated with pigments and fillers, please contact Bluestar Silicones' technical support for more information.

•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.

• Curing inhibition may occur in contact with certain materials containing tin salts, amines or sulphur. A preliminary test is always recommended.

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 7537 A/B MUST be used within the shelf life limits stated on the label. 

• To preserve product properties the following conditions must be observed:

- The original closed packaging must be kept at ambient temperature. 

- The product must be used as soon as the package is opened. 

When the above conditions are not met, Bluestar Silicones can no longer guarantee that the product will meet the sales specifications.

Please consult the Safety Data Sheet of this product.
