BLUESIL SLT VEC 90 gives primerless adhesion on clear glass.

Certain thermo-lacquered aluminiums also give good adhesion after degreasing (e.g.with F spirit).

For all other surfaces, and in view of the expected performance levels in Structural Glazing applications, it recommended to initially apply a primer (BLUESIL PRIM 10073).

It has perfect compatibility with most commercial seal backings.

Comment: apart from clear glass applications, preliminary project specific testing must be carried out for all other surfaces.

BLUESIL SLT VEC 90 BLACK may be stored at temperatures between 2°C / 36°F and 30°C / 86°F for up to 18 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


BLUESIL SLT VEC 90 is a one-component silicone elastomer with high mechanical properties mainly intended for applications using so called Structural Glazing technique.

It cures at room temperature and in the presence of air humidity to form a strong, flexible seal.

BLUESIL SLT VEC 90 exhibits:

  • High mechanical properties suitable for structural glazing applications.
  • Easy processing using simple dispensing machines.
  • A high cure rate.
  • Primerless adhesion to most materials encountered in the structural glazing market.
  • Outstanding natural ageing resistance and maintaining of properties in extreme service temperatures.

BLUESIL SLT VEC 90 is mainly intended for Structural Glazing assembly applications.

Its good temperature resistance also means that it can be used in sealing applications at extreme temperatures (e.g. 150°C continuous).
