POLYUREA RAYSTON Pure polyurea membrane for waterproofing in spray applications. DESCRIPTION TECHNICAL DATA Polyurea Rayston is a 2-component polyurea system for elastic membrane application with crackbridging capability. It is an extra fastcuring system that can only be applied by hot mechanical spraying equipment. Polyurea Rayston can be combined with different geotextiles to obtain on site applied, seamless INFORMATION ON THE PRODUCT BEFORE APPLICATION Packaging Note: Pigment is delivered in a third container. See Pigment Spray data sheet for specific details. Waterproofing of foundations, especially those designed as barriers to Radon gas. Roof Lead content Aromatic isocyanate prepolymer Component C (pigment paste) Metal can (4 kg or 0.4 kg) Non-volatile content Physical state Component A Chemical description Flash point Colour Yellow (without pigment) (may darken along wastewater treatment structures. On-site applied liners, totally seamless, for secondary containment applications, ponds, landfills, tunnels, canals, dam repairing. Protective coating for metallic structures Polyurea Rayston can be completed with an aliphatic polyurethane topcoat to ensure UV protection. Crack-bridging capability. Highly elastic membrane. Very fast curing, using twocomponent spraying equipment. Fast polymerization (see pot life data) Dark yellow, but component A is pigmented by addition of pigment paste (Pigment Spray) delivered with each kit of Polyurea Rayston.
