Koster PUR 2-in-1

KOSTER 2 IN 1 acts like a single component injection resin if it comes into contact with water. In this case, it reacts to form a highly elastic foam. KOSTER 2 IN 1 acts like a two component injection resin under dry conditions. KOSTER 2 IN 1 remains elastic after reacting. It is able to follow crack movements and seal cracks permanently with an elastic polyurethane solid resin without the need for follow-up injections. KOSTER 2 IN 1 is a fast reacting foam for the short term closure of leaks as well as an elastic solid resin for permanent closure of cracks. KOSTER 2 IN 1, therefore, combines two resins into one product. KOSTER 2 IN 1 is solvent free and is resistant to hydrolysis.

Fields of Application

KOSTER 2 IN 1 stops active leaks and seals cracks and construction joints permanently and elastically. It can be injected into dry and wet cracks, and can be used to fill voids.

Application

Before injection, seal crack faces using KOSTER KB-Fix 5. Minimum application temperature is 40°F. Bring the material up to 60°F before mixing and injection. Temperatures above 77°F will increase reaction rate and reduce pot life. Perform injection using a conventional single-component injection pump such as the electrical KOSTER 1C Injection Pump. Drill holes on alternating sides along the course of the crack at an interval of 4 - 6 inches. Insert injection packers into the holes and (when possible) inject from bottom to top. The diameter of the drill holes depends on the injection packers chosen. Perform injection in two stages:

  • 1) Inject KOSTER 2 IN 1 until the resin is discharged as foam from the adjoining drill hole or the surface of the crack.
  • 2) Re-inject KOSTER 2 IN 1 within 10 to 15 minutes of the initial injection. Perform the follow-up injection within the pot life of the initially injected material. When filling large, wet voids, wait at least 1 hour.
