Construction Adhesive and Sealant (Polyurethane, Silicone, Isocyanate) — household safety profile
Moderate riskConstruction adhesives (Liquid Nails, PL Premium, Gorilla Glue) and sealants (silicone, polyurethane, acrylic latex).
What is this product?
Construction adhesives (Liquid Nails, PL Premium, Gorilla Glue) and sealants (silicone, polyurethane, acrylic latex). Polyurethane adhesives: contain MDI (methylene diphenyl diisocyanate) — a potent respiratory sensitizer. Once sensitized to isocyanate, any future exposure causes severe asthma. Silicone sealant: releases acetic acid (vinegar smell) during cure. Solvent-based construction adhesive: VOC content 100-300 g/L. Low-VOC and water-based alternatives have dramatically improved in performance.
