Joint dimensions:
The movement capability of sealant as well as local regulations must be considered. Joint width should be twice the depth.

Joint preparation:
The joint faces to be bonded must be clean, dry and free from dust, oil, grease, old sealant and any traces of contaminant which may affect adhesion. Surfaces should be degreased with solvent soaked cloth and then wiped with a clean cloth. To remove dust, use oil-free compressed air.

Priming:
Although BLUESIL SLT 3E will bond well to most clean and dry surfaces, it is recommended that a primer be used on certain substrates in order to ensure a strong and uniform bond :

  • Steel, ferrous metals, thermoplastic materials.BLUESIL PRIM 10073
  • Concrete, stone, wood.BLUESIL PRIM 12076

On non-porous substrates, the primer should be applied with a cloth or soft brush in a thin and uniform film. On porous substrates apply with a brush in the case of particularly porous material apply a second layer after drying.

Sealant application:
For good performance it is essential that the sealant be only bonded to the two facing sides of the joint to achieve this, install a backup material (closed cell polyethylene or open cell polyurethane foam). Apply the sealant in a continuous operation, making sure that all air pockets or voids are eliminated. Tool the sealant with light pressure to spread the material against the joint surfaces. This operation should be made with a dry spatula before skin formation occurs.
Excess uncured sealant should be wiped and cleaned with a commercial solvent. Cured sealant can only be removed by scraping (i.e. with a razor blade), or with a special silicone remover product.

STORAGE -5°C 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

BLUESIL SLT 3E WHITE

BLUESIL SLT 3E is a one-component silicone sealant which, when exposed to atmospheric humidity, forms a flexible and durable elastomeric seal which possesses excellent resistance to severe weathering conditions.

BLUESIL SLT 3E bonds well to clean uncoated glass, ceramics, most glazed non-porous surfaces and anodized aluminium without the need to prime. The rheological properties of BLUESIL SLT 3E allow high rates of extrusion whilst the thixotropy enables the sealant to be used on vertical jointing and underside applications.
BLUESIL SLT 3E presents excellent stability to temperature variations (-30°C to +120°C), UV rays, rain, snow...

BLUESIL SLT 3E is a general purpose silicone sealant which offers good performance on many different applications where weathertightness is required:

  • Caulking doors and windows
  • Shop windows, display cases, panels and signs
  • Plumbing, drains, guttering
  • HVAC ducting
  • Sealing of electrical conduit
  • Boat maintenance
  • DIY general purpose sealing
