ADCOTHERM™ PIB 32 is a gray polyisobutylene based sealant that exhibits excellent long-term stability and remains permanently flexible, even at low temperatures. PIB 32 is available in a pre-extruded bead rolled onto release liner. Like all ADCOTHERM™ PIB sealants, ADCOTHERM™ PIB 32 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 32 is supplied in pre-extruded strands for manual assembly of insulating glass units.

ADCOTHERM™ PIB 32 may also be used to patch corners, extrusion skips, or for general repair of primary sealant application. PIB 32 may be used as a spot repair in combination with all other ADCOTHERM™ gray PIB products on a single insulating glass unit.

ADCOTHERM™ PIB 32 has very low moisture vapor transmission rates (MVTR) and gas permeability rates. Properly constructed dual-seal units incorporating ADCOTHERM™ PIB 32 will retain argon insulating gas and maintain a dry interior unit airspace for decades. Insulating glass units produced with ADCOTHERM™ PIB 32 routinely pass ASTM E2188, E2189, E2190 (HIGS) standards.

ADCOTHERM™ PIB 32 may be used with most commercially available urethane, silicone, polysulfide, or butyl hot melt insulating glass secondary sealants.

Performance Standards

Insulating glass units incorporating ADCOTHERM^TM PIB 32 routinely meet the following specifications:

• ASTM E 774

• ASTM E 2188, E2189, E2190 (HIGS)

• CGSB 12.8

• EN 1279 (Part 1-3)

Application Instruction

See ADCOTHERM™ PIB Application Guidelines

ADCOTHERM™ PIB 32 Gray is available in the following standard packages:

Limitations

• ADCOTHERMTM PIB 32 is not intended for use as a structural sealant.

• ADCOTHERMTM PIB 32 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.
