NR-900 : INTEGRAL CORROSION INHIBITOR FOR CONCRETE AND COATING MATERIALS FOR STEEL BARS.

DESCRIPTION:

NR - 900 is a light yellowish liquid or powder, ready to use integral corrosion inhibitor for concrete :;Kar It can be applied on steel bars as protective coating to prevent corrosion. The mechanism titer corrosion prevention by NR-900, corrosion inhibitor is that it helps to form a passive membrant asm the surface of reinforcing steel. The Product satisfies the requirement of M.O.S.T specification :  Inhibitor Solution under Apendices 1000-1 and vide Patent No. 109784/67. The product is oTimended for use where marine sand or subsoil waters containing high soluble salts are present in concrete. Also for long life of reinforcing steel bars in concrete, the protective film on (the surface of the reinforcing steel prevents rusting&consequently impairs concrete durability.

THE COUNTER MEASURES SUGGESTED ARE:

• Lower the water-cement ratio as much as possible by the use of 'CEMWET - SP' super plasticizer and make dense concrete.
• Place concrete precisely in accordance with specification, as well as to increase protective covering.
• Use good corrosion inhibitor- NR-900. o    Finish concrete surface carefully to make it dense.
  

BENEFITS :

• Integral Corrosion inhibitor, highly effective for preventing rust.
• It works for long period of time.
• Workability, Strength and quality of concrete are not affected.
• Its rust preventing effect is greatly improved.

AMPLICATION :
a) NR-900 is added to concrete mis at the point of use along with cement, sand, aggregate and water. The dosage of 1 % of NR-900 by weight of cement or 500 gins/bag of cement(50 kg) is adequate.

b) For steel bars:600gm of NR-900 with 1kg of cement to be added and stir it properly. Then apply with a brush on steel bars.

COVERAGE :3 to 3. 5 Sq. meter per kg of NR-900 on steel surfaces.
PACKING : In steel barrels of 220kg. Net Weight
ADVANTAGES: No solvent,No fire hazards,Odourless, Non-toxic.
STORAGE: Unlimited shelf-life when stored in well sealed containers in well sealed Containers in frost-free condition.
