Surface preparation:
All surfaces must be clean and dry, and free from any dust or any traces of contaminants which may affect adhesion.
To degrease, wipe with a pad soaked in solvent then with a clean cloth. Dust should be removed using oil-free compressed air.
BLUESIL SLT NOVART does not require a primer on most common substrates, except in the case of immersion, mainly with porous substrates. Please consult us for more information.

Joint dimensions:
They must take into account the joint movement in addition to local regulations. In order to allow the sealant to operate under the best possible conditions, the minimum cross-section of the seal should be 5 x 5 mm: for seals wider than 12 mm, the thickness will generally be determined as being half this width.

Applying the sealant:
Once a seal back-up material has been put in place (closed-cell polyethylene foam with surface skin or open cell polyurethane foam), the sealant should be applied ensuring that the seal is completely filled. Tool the seal to ensure good contact between the sealant and the bonding surfaces. This should be carried out using a spatula before the surface skin is formed.
Areas soiled with fresh sealant may be cleaned with a dry pad or a pad soaked in a solvent (compatible with the substrate). Any cured sealant can be removed by scraping (e.g. using a razor blade), or by using a special silicone remover product.

Avoid discharge into drains, water courses or onto the ground. Store in tightly closed original container. Store in a cool, dry place with adequate ventilation. Keep away from incompatible materials, open flames, and high temperatures. Avoid contact with oxidizing agents. Vulcanises at room temperature on contact with moisture in the air. For further information, refer to Section 10: "Stability and Reactivity". Suitable containers: Steel drums coated with epoxy-resin.Please consult the Safety Data Sheet of this product.RoHS;VOC


BLUESIL SLT NOVART is a one component, neutral and fast curing, ready-to-use silicone elastomer suitable for weather-sealing and bonding seals in construction applications. It crosslinks at room temperature to give a flexible seal of low modulus.
BLUESIL SLT NOVART can withstand movement of 25 % in constant service throughout a wide temperature range.

BLUESIL SLT NOVART combines the advantages of primerless adhesion and neutrality and can be used on numerous substrates such as: glass, coated glass, anodised and heat lacquered aluminium, steel, stainless steel, rigid PVC, concrete and other porous substrates.
Once cured, BLUESIL SLT NOVART is highly resistant and is not affected by exposure to sunlight, rain, snow and ozone and maintains this resistance over many years.

BLUESIL SLT NOVART is suitable for weather-sealing and bonding seals for construction and glazing applications such as:

  • Perimeter sealing of wooden, aluminium and PVCu window and door frames,
  • Glazing applications,
  • Expansion joints for facade panels, Curtain wall joint,
  • Ventilation ducts and piping passages,
  • Boat, caravan and camping-car maintenance.
