ADCOTHERM™ PIB 32 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 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 specifically formulated to be used as a primary sealant in insulating glass units for commercial construction. PIB 32 is compounded with high levels of UV stabilizing agents to provide maximum protection in exposed applications such as direct glazing.

ADCOTHERM™ PIB 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. Color variation in PIB 32 is tightly controlled via a colorimeter and PIB 32 will never exhibit black streaking.

ADCOTHERM™ PIB 32 offers high application rates without sacrificing strength performance. PIB 32 is designed to run well on high-volume, fully automated application equipment as well as manual butyl extruders. 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™ PIB 32 routinely meet the following specifications:

• ASTM E 774

• ASTM E 2188, E2189, E2190 (HIGS)

• CGSB 12.8

• EN 1279 (Part 1-3)

Limitations

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

• ADCOTHERM™ 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.

Storage and Shelf Life

Store material in original unopened packaging at temperatures between 40°F-100°F. Shelf life is 24 months when stored as recommended.

Prior to working with this or any product consult product label and Material Safety Data Sheet (MSDS) for necessary health and safety precautions.
