ADCOTHERM™ PIB 1 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 1 exhibits low argon permeability and inherently low moisture vapor transmission along with excellent adhesion to aluminum, stainless steel and tin-plated steel spacer substrates.

ADCOTHERM™ PIB 1 is specifically formulated to be used as a primary sealant in insulating glass units which are produced via horizontal or stacked methods. PIB 1 compression properties have been optimized to provide sufficient wet-out after pressing while minimizing over-compression issues in a bottom-of-the-stack unit. ADCOTHERM™ PIB 1 exhibits reduced flow versus other PIB offerings when submitted to a set pressure.
ADCOTHERM™ PIB 1 has very low moisture vapor transmission rates (MVTR) and gas permeability rates. Properly constructed dual-seal units incorporating ADCOTHERM™ PIB 1 will retain
argon insulating gas and maintain a dry interior unit airspace for decades. Insulating glass units produced with
ADCOTHERM™ PIB 1 routinely pass ASTM E2188, E2189, E2190 (HIGS) standards.
ADCOTHERM™ PIB 1 is designed for use on manual extrusion equipment. PIB 1 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 1 routinely meet the following specifications:
• ASTM E 774
• ASTM E 2188, E2189, E2190 (HIGS)
• CGSB 12.8
• EN 1279 (Part 1-3)

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.
Limitations
- ADCOTHERMTM PIB 1 is not intended for use as a structural sealant.
- ADCOTHERMTM PIB 1 is not intended for use on fully-automated, high-volume extruders.
- ADCOTHERMTM PIB 1 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.
