Novaseal ^®

Hot melt Insulated Glass Sealant

Description:

Novaseal is a butyl based, high strength hot melt sealant designed specifically for the production of sealed insulated glass units.  Novaseal is a monocomponent hot melt sealant, 100 % solid.  Its formulation gives outstanding adhesion to glass, aluminium and  galvanized   steel. Novaseal is resistant to UV, high and low temperatures and water.  Novaseal has exceptional performance under environmental exposure to ultraviolet light, temperature extremes and moisture. It is formulated to meet the specification of ASTM E773/E774.

It offers the following benefits :

§     No premixing required : - no waste

§     Fast setting :    - quick  unit  handling. Under normal conditions the sealant will set in 2 minutes. Units can be transported within 5 minutes.

§     Excellent adhesion :- to glass and all spacer bars including mill finished and anodised aluminium, galvanised steel and polycarbonate.

Application instruction :

Glass units should be cleaned and dry before applying the aluminium spacer frame. Spacers can be made out of galvanized steel or aluminium. There is no incompatibility risk. Corner keys should be rigid enough to hold the whole frame during assembly operation and, subsequently, during the service life of the insulated glass unit.  They should be of size that will not reduce the amount of  Novaseal in the corner. The dessicant   should be filled in spacers in proper quantity. Apply Novaseal at proper temperature.

Place the sealed unit in a horizontal position ensuring that the cavity width and depth dimensions are satisfactory and that the cavity surfaces are in a clean, dry condition.

Under normal circumstances the depth of cavity seal should be a minimum of 6 mm and no more than 8 mm.   Where shaped back spacer is used, a minimum cover of 2 mm is required between top of spacer and outer edge of seal.  For abnormal sealant cross sections, including multiple units, contact us.

Apply the sealant to the unit by means of a suitable hot melt applicator, a sealant temperature, ex-nozzle, of between 180 °c and 195 °C being recommended.

Basic Use:

Novaseal is formulated to provide a primary moisture barrier for insulated glass units. It is designed for use with hand extrusion equipment.

Heat Stability : 

Novaseal is not significantly affected by being subjected to prolonged heat at normal application temperature, or by subsequent cooling and re-heating between production periods.

Packaging:

Novaseal is available in the following packaging:
3 kg slugs and 18 kg drums.

Health & Safety:

A complete Material Safety data sheet (MSDS) is available for health and safety precautions

The information on this data sheet is based on our experience and given to the best of our knowledge. All data given are average values (guidelines under normal conditions). They do not represent legally binding properties.

Special Advice:

When installing sealed IG units only solvent- and plasticiser free secondary sealants should be used. Where direct contact between primary and secondary sealant is possible, their compatibility should first be checked. The same applies to coatings and other materials insofar as direct contact is possible.
