Pur 222 Polyurethane Injection Silicate Resin Chemical Material

Yapı Kimya PUR 222 Polyurethane Injection Silicate Resin Chemical Material

Yapı Kimya PUR 222 is a special chemical developed for high-performance injection and water insulation in areas in contact with water. Its ability to change the reaction time according to the flow rate of water makes PUR 222 an ideal solution for both fast and controlled applications. Thus, maximum efficiency is achieved in stopping internal leaks, filling cracks, and injecting voids.

PUR 222 is available in two different forms: fast curing and slow curing. It provides instant intervention by ensuring a rapid reaction in areas with high water flow; in applications where low flow and wider coverage are required, the slow curing form provides optimum working time. The product easily adapts to different application requirements with A–B component options with mixing ratios of 1:1 and 10:1.

PUR 222, commonly used in tunnels, foundations, curtain walls, basements, water tanks, and underground applications, offers long-lasting water stopping performance in both indoor and outdoor environments. It is compatible with low and high-pressure injection pumps and provides long-term stabilization in the applied area.

Our technical service team helps you achieve the best results by providing professional guidance on the correct mixing and application stages of the product.
