ADCOTHERM™ PIB 7HSNB is a black polyisobutylene based sealant that exhibits excellent long-term stability and remains permanently flexible, even at low temperatures. Like all ADCOTHERM™ PIB sealants, ADCOTHERM™ PIB 7HSNB 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.

Easily dispensed	Dispensing viscosity will support production rates on high-volume automated extruders
Low moisture vapor transmission rate (MVTR)	Increased unit life expectancy
Excellent resistance to weathering	Does not degrade upon exposure to environmental conditions
Low gas permeability	Increased argon gas retention beyond industry standards
Excellent adhesion to glass, stainless, aluminum, tin-plated steel, and many plastics	Can be used with all commercially accepted metal spacer systems and most plastic spacer systems
Ultra low volatile content	No chemical fogging. No discoloration of low-e coatings

ADCOTHERM™ PIB 7HSNB is specifically formulated to be used as a primary sealant in insulating glass units which are produced on high speed vertical application equipment. PIB 7HSNB offers high application rates without sacrificing strength performance.

ADCOTHERM™ PIB 7HSNB has very low moisture vapor transmission rates (MVTR) and gas permeability rates. Properly constructed dual-seal units incorporating PIB 7HSNB will retain argon insulating gas and maintain a dry interior unit airspace for decades. Insulating glass units produced with ADCOTHERM™ PIB 7HSNB routinely pass ASTM E2188, E2189, E2190 (HIGS) standards.

ADCOTHERM™ PIB 7HSNB is designed to run well on high-volume, fully automated application equipment as well as manual butyl extruders. PIB 7HSNB may be used with most commercially available urethane, silicone, polysulfide, or butyl hot melt insulating glass secondary sealants.

Application Instruction

See ADCOTHERM™ PIB Application Guideline

Limitations

• ADCOTHERM™ PIB 7HSNB is not intended for use as a
  structural sealant.
• ADCOTHERM™ PIB 7HSNB 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.

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.
