Single Component Polyurethane Sealant
A Common Product profile (CP) is a type of data record originally developed as part of a collaboration called the Quartz Project. The profiles are not specific to any manufacturer, but list the substances that are most commonly present in a product type. The CPs include a general description of the product type, a list of the most common substances serving each function in the product, and the health hazards associated with these substances. See the CP methodology here for more information.
This CP presents research done by Healthy Building Network alone following the completion of the Quartz effort.Representative Manufacturers
Single component polyurethane sealants are primarily made of a polyurethane prepolymer, filler, plasticizer and solvent. Additional additives including moisture scavengers, catalysts and adhesion promotors are commonly included in these formulations. The sealants covered in this CP are moisture-cured, so the prepolymers crosslink after application in the presence of moisture. These smooth, non-sag, low modulus elastomeric sealants can be used in interior or exterior joint sealing applications such as expansion and control joints, siding gaps, gaps around perimeters of doors and windows, and other wall penetrations. They are typically paintable and meet ASTM C920 Type S, Grade NS with a minimum joint movement capability of +/-25%.
This information reflects our best understanding of product composition in 2016.
