MetaLink is a highly elastic seam sealer, designed to bond and seal duct work in HVAC, solar photovoltaic systems and mechanical construction applications. MetaLink is also effective for sealing automotive seams, RV's, and transportation equipment where corrosion from salt spray, and vibration and joint movement is severe. The product is solvent free and contains no isocyanates.

MetaLink will not shrink upon curing, will not discolor when exposed to UV light, and can not "out-gas", or bubble, on damp surfaces as urethane sealants often do. The product has resilient "elastomeric" properties and excellent adhesion to most construction materials.

MetaLink is capable of joint movement in excess of 50% in both compression and extension. MetaLink can be used effectively in many difficult construction site conditions, cures and in wet or dry climate conditions and at low temperatures 30°F (-2°C).
