The Loctite 5510 Adhesive/Sealant is a permanently elastic, primerless formulation that is able to bond and seal a variety of dissimilar substrates, including metals, glass, nylon and plastics. The single-component, oderless adhesive is free of solvents, isocyanates, PVC or silicones. It bonds and seals simultaneously, skinning over relatively quickly and cures to a tack-free surface in 24 hours. Able to fill gaps, resist weather and moisture and withstand ongoing shock and impact, it has many potential uses, including air/water penetration joints, expansion joints, doors, windows, wall penetrations or precast panels. The sealant is available in white, black or gray. Henkel Corp.; 800-562-8483; www.loctite.com.
