ADPRENE 1200 PU2
ADPRENE 1200 PU2 is a one component, solvent free, polyurethane injection grout ideally suitable for crack or water leaks in concrete and masonry structures. ADPRENE 1200 PU2 is to be injected with a one-component pump with 6 to 10% catalyst. Reaction with water yields a polyurethane hard foam (slightly flexible). The formation of gas makes the foam penetrate very well into the cracks. The reaction speed can be adapted easily by varying the accelerator or catalyst content from 6 to 10 %. The more catalyst is added, the faster the reaction proceed. The end product neither shrinks nor swells. A good compression strength is obtained in a very short time.
Uses
-
Sealing of Cracks in both Dry and underwater conditions.
-
Can be used in repairing of RCC Water tanks to treat the horizontal & vertical cracks and leakages under intensive moisture conditions also.
-
Can be used in hygienic structures like Hospital, Pharmaceuticals and food processing industries.
-
Can be used for the repairs of dams, jetties and break water structures for application below water line.
-
Chemical resistant coating
-
Chemical resistance tank linings
Advantages
-
Excellent to use under hydrostatic pressure.
-
Excellent chemical and thermal resistance
-
High mechanical strength
-
When reacted with water yields a polyurethane hard foam slightly flexible.
-
Solvent free
-
Effectively seals cracks and leakages in concrete as formation of gas makes the foam penetrate very well into the cracks
-
It is low viscosity PU.
-
It is single component which require nominal addition of catalyst and hence easy to use.
-
Eco friendly product.
- Packaging: 10 kg Drum + 1 kg catalyst.
- Colour: OPART A – Yellowish brown liquid. , PART B – Clear to Yellowish liquid.

INSTALLATION
Surface Preparation
All surfaces should be, clean and free of all dirt, oil, grease, concrete sealers etc. All visible cracks, honey combs, loose concrete shall be removed and fixed with repair mortar. Remove the dust by compressed air or paint brush or wiping with water soaked cloth.
Mixing
Take the PART A 10 Kg in mixing vessel and stir it using heavy/medium duty slow speed mechanical mixer/ stirrer. In a mixing vessel, slowly add catalyst component 1 Kg and continue to stir thoroughly to achieve homogenous mix
Application
Pour the mixed material in pump feed tank and increase the pressure gradually till desired injection. Used the mix material as soon as possible.
STORAGE
Material should be stored off the ground in a dry area under controlled atmosphere (in hot temperature store at place less than 30 C).
* High humidity will reduce the shelf life of packed product.
