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 7531 A is also suitable for laminating and transfer coating processes. Fillers and pigments can possibly be added.

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 7531 A 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.


BLUESIL TCS 7531 A is a two-component heat curing liquid silicone elastomer which cures by a polyaddition reaction. All products from the Textile Coating System product line are specially engineered for textile coating applications.

2 Part RTV

  • High bond strength without primer on textiles (PA, PET, glass fabric…).

  • Allows low coat weights (< 30 g/m²).

  • Medium viscosity and easily pumpable to sustain high coating speed.

  • Fast cure at elevated temperature.

  • Provides high tear strength and edge comb resistance to the coated fabric.

  • Low thermal conductivity (high insulation properties).

  • Solventless technology.

  • Long bath life at room temperature (> 16h).
