ADCOTHERM™ PIB 8HSNB is a gray polyisobutylene based sealant that exhibits excellent long-term stability and remains permanently flexible, even at low temperatures. Like all ADCOTHERM™ PIB sealants, ADCOTHERM™ PIB 8HSNB exhibits low argon permeability and inherently low moisture vapor transmission along with excellent adhesion to aluminum, stainless steel and tin-plated steel spacer substrates.

NOTE:

The foregoing information is published as general information only. The listed properties and performance characteristics are typical values and are not to be interpreted as manufacturing specifications.

ADCOTHERM™ PIB 8HSNB is specifically formulated to be used as a primary sealant in insulating glass units which are produced on high speed vertical application equipment.

ADCOTHERM™ PIB 8HSNB offers high application rates without sacrificing strength performance.

PIB 8HSNB has very low moisture vapor transmission rates (MVTR) and gas permeability rates. Properly constructed dual-seal units incorporating PIB 8HSNB will retain argon insulating gas and maintain a dry interior unit airspace for decades. Insulating glass units produced with ADCOTHERM™ PIB 8HSNB routinely pass ASTM E2188, E2189, E2190 (HIGS) standards.

ADCOTHERM™ PIB 8HSNB is designed to run well on high-volume, fully automated application equipment as well as manual butyl extruders. PIB 8HSNB may be used with most commercially available urethane, silicone, polysulfide, or butyl hot melt insulating glass secondary sealants.

Application Instruction

See ADCOTHERM™ PIB Application Guidelines

Limitations

• ADCOTHERMTM PIB 8HSNB is not intended for use as a structural sealant.
   
• ADCOTHERMTM PIB 8HSNB is not resistant to attack by solvents, oils, and plasticizers. When constructing IG with silicone secondary sealants, care must be taken to insure that the glazing environment (including setting blocks, compression gaskets, glazing sealants, and weatherproofing sealants) is free from solvents, oils and plasticizers. These chemicals can migrate through silicone secondary sealants and attack the primary sealant resulting in premature IG unit failure.

• 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-film forming, low residue detergent and rinsed thoroughly with clean hot water.

Packaging

ADCOTHERM™ PIB 8HSNB Gray is available in the following standard packages:

Glazing Compatibility

It is recommended that glazing materials be tested for compatibility and that all units be glazed in accordance with GANA (Glass Association of North America) and IGMA (Insulating Glass Manufacturers Alliance) recommendations. Contact with any solvent, oil, or plasticizer-containing glazing materials should be avoided.
