U-Seal 816 is a one-component, self-levelling, pourable grade polyurethane concrete pavement sealant. It cures under the influence of atmospheric moisture to form a high-performance compound with permanent elasticity and resistance to ageing and weathering. U-Seal 816 is based on NPT LC-Technology, developed to avoid bubbling present in traditional one-part PU Sealants. LC-Technology combines the best properties of traditional polyurethane sealants to a bubble-free curing system and very low emissions.
Areas of ApplicationU-Seal 816 has been specifically developed to be used as a pourable joint sealant in rigid pavements in airfields, roads, concrete floors where high adhesion, abrasion-resistance and high chemical resistance to fuels, oils and hydrocarbons is required.
