Description

PU FLEX

High Performance Two Component PU Adhesive (5TS2 R2T)

Product Description

PU FLEX is two component Polyurethane Adhesive, designed for permanent bonding of wide range of all types of tiles, glass mosaic, sensitive natural marbles, granite stones slabs and synthetic / engineered stone on interior & exterior walls and floor areas. PU FLEX adhesive is also suitable for superior bond strength on substrates such as plywood, glass or metal. It also provided balanced thixotropic and superior performance elasticity ensured by the use of stabilized polyurethane resin for rapid and secure laying operations on high deformable and high-expansion substrates.
