Hot Melt Butyl Sealant for Insulating Glass

Hot Melt Butyl Sealant for Insulating Glass is one part polyisobutylene PIB based material, totally solvent free especially formulated for use as the primary seal in double sealed units. PIB allows for minimum water vapor and gas permeation.

The P.I.B butyl sealant has excellent adhesion properties to glass and metal spacer systems and can be used together with conventional secondary sealants.

It work for the edge of spacer frame by PIB machine, the sealant can be removed from glass without any pollution on glass.

Features:

1.Very low moisture vapor transmission rates (MVTR) and gas permeability rates.
2. Properly constructed dual-seal units incorporating the PIB butyl sealant will retain argon insulating gas and maintain a dry interior unit airspace for decades. 
3.PIB butyl sealant able to be used with most commercially available silicone, polysulphide or butyl hot melt insulating glass secondary sealants.
4.Without any smell

Typical Properties:

Packing:

8.0kg per pc, 4 pcs per carton.

Storage:
24 months store in original unopened packaging at temeprature between 10 to 30 Celsius degree.

Use:

The surfaces to be bonded must be dry, clean and free from dust and grease. Glass surfaces should be
thoroughly cleaned by hand or machine with non-i lm forming, low residue etergent and rinsed thoroughly with clean hot water, the P.I.B butyl sealantshall be applied at a temperature between 140 to 150 degree Celsius with butyl hot melt extruder machine, please check with extruder equipment manufacture for optimum equipment settings.

Note:
It is recommended that glazing materials be tested for compatibility.
Contact with any solvent, oil, or plasticizer-containing glazing materials should be avoided.
