رزین پلی یورتان تزریقی PenePurFoam 65
Description
Single component hydroactive injection polyurethane resin of low viscosity. The presence of water is necessary for the polymerization reaction to proceed. In contact with water makes foam filling the free space, forms a dense waterproof rigid foam with a closed fine-cellular structure.
Purpose
- Active leaks stopping;
- Sealing of mobile and static cracks of opening more than 0.15 mm;
- Filling voids in building structures
Advantages
- Active reaction with water with a significant increase in volume;
- The possibility of accelerating the time of polymerization using a catalyzer;
- Resistance to sea water and other aggressive environment

INSTRUCTIONS FOR USE OF PENEPURFOAM 65
Works should be performed at the temperature of the surface of the structure from +5 to +35 ° С.
Security measures
Use chemical-resistant rubber gloves, cotton gloves, respirator, goggles, thick cloth, boots. In case of contact with the skin or eyes, immediately rinse with water and consult a doctor.
Surface cleaning
Rinse the joint cavity, cracks with water using a pump or high-pressure water jet cleaner
Pump preparation
Use the hand pump “EK-100M” or electric “EK-200”. Before using the resin, test the pump with flush hydraulic oil (for example, Mobil HLP-68 or its equivalent) in the circulation mode
Installation of injectors
Usually use metal injectors with a ball valve. The diameter of the holes should be 1-2 mm more than the diameter of the injector (for example, if the diameter of the injector is 10 mm, the diameter of the hole should be 11–12 mm).
- drill holes for injection at an angle of ~ 45 ° to the surface; the distance between the holes and the indent from the edge of the crack, cold joint should be 1/2 the thickness of the structure
- clean the holes with compressed air from drilling residues and install a final injector;
- on the vertical and ceiling surfaces, prevent resin from flowing out, for which a 25 × 25 mm racking should be made along the crack mouth and filled with Skrepa M500 Repair
Resin preparation
Important! The temperature of the resin should not be below +17 ° C. With decreasing temperature, viscosity increases, and with increasing temperature, pot life decreases.- Choose the amount of catalyzer based on the filtration rate of water and ambient temperature (see table);- Before preparing the working volume of the resin, make a control mixture to assess the pot life of the resin under the conditions of the object;- Prepare the amount of resin that can be consumed during the estimated pot life: mix resin with catalyzer within 3 minutes and stir it manually or by a low-speed mixing drill (up to 300 rpm).

Injection work
Important! Injection of resin into vertical cracks should be carried out by sequential injection from the bottom up.
- Inject until a pressure increase occurs or the resin begins to flow from the next hole;
- Install the next injector and continue the injection process;
- If the viscosity of the resin increases, wash the pump with a solvent (for example, solvent 646 GOST 18188) and prepare a new batch of resin;
- After the main injection, carry out additional injectors already filled with resin before its polymerization begins;
- If it is necessary to remove the injectors, fill the bore-hole cavity with the Penecrete mortar mix
Pump cleaning
Firstly, flush the pump and sleeves with solvent first (for example, xylene or solvent 646 GOST 18188), then with hydraulic oil (for example, Mobil HLP-68 or its equivalent). Remove cured resin mechanically.
