PIB Primary Sealant Polyisobutylene is used as the primary moisture barrier seal in all dual-seal insulated units. While PIB has excellent MVT (moisture vapor transmission), it lacks mechanical strength and needs to be used in conjunction with a secondary edge sealant such as polyurethane, polysulphide or silicone. ADCO offers a variety of PIB materials for use in various manufacturing situations. ADCO PIB sealants can be applied at reduced temperatures which translates into energy cost savings. Easy dispensing provides improved quality and production rates as well. ADCOTHERM PIB offers competitive advantages such as: Low MVTR which increases the IG unit life expectancy. Low gas permeability which means argon-filled units retain their gas charge longer. Increased strength compared to other PIB materials on the market – this helps reduce glass movement during assembly and post production. Improved flow rates that support increased production rates without sacrificing performance. Reduced application temperatures which requires less energy and further reduced costs ADCOTHERM PIB can be applied with a variety of application equipment, from manual operations to high speed automated extruders. Specific formulations are available depending on your application process.   (See PIB Comparison Chart) PIB 7HS Black & 8HS Gray for high speed automated linear extrusion equipment PIB 29 Black for European extruders PIB 1 Black & 2 Gray for hand-gun operations – horizontally stacked PIB 3 Black & 4 Gray for hand-gun operations – vertically stacked PIB 11 pre-extruded PIB for hand operations.

It’s so good that our competition buys their PIB from us to sell with their own sealants.
