MICRO-CRYSTAL DEVELOPMENT TECHNOLOGY (MCDT)
This indicates, that each crystal nucleus of Steel Guard NanoCoat™ has POWER OF ATTRACTING other cement molecules to it by the virtue of crystal forces and it forms a TRAP for all these molecules which do not possess sufficient energy to escape. Chemisorption is yet another important reaction which is taken place during formation of coat where molecules are held on steel surface by chemical bonds formed between nanocoat molecules and steel molecules, here heat of adsorption is higher and is very difficult to reverse the process i.e. only heating to high temperature can reverse the chemisorptions.
Each crystal of Steel Guard NanoCoat™ is cubic shaped (like crystal of diamond) with 4 threefold axes which helps to increase adherence to steel and concrete simultaneously. Another important feature of Steel Guard NanoCoat™ is its coating thickness which is 0.2 microns approximately. It is so thin still tenacious that it does not change the dimension of steel bar or panel and does not affect rebar structure. Another important reason for increase in bonding strength to around 100% is nanocoat’s physicochemical structure, due to which the active chemical formulation hides inside dense forest of micro-crystals and form chemical net to attract minute cement particles. This forms strong bond between steel & cement.
THE CONCEPT OF ‘LIVE’ COAT:
ACTION WITH PAINT
AS SOON AS THE PAINT/ TOPCOAT COMES IN COANTACT WITH THE NANOCOATED STEEL, THE MICROCRYSTALS FORMED ON THE COATED STEEL SURFACE GET UNLOCKED AND ATTRACT THE PAINT RESINS AND BOND TOGETHER PERMANENLY.
THIS EXTRA BONDING OF PAINT WITH NANOCOATED STEEL SURFACE PREVENTS RUSTING IN FUTURE.
ACTION WITH CEMENT
AS SOON AS THE CEMENT CONCRETE SLURRY COMES IN COANTACT WITH THE NANOCOATED STEEL BAR, THE MICROCRYSTALS FORMED ON THE COATED STEEL SURFACE GET UNLOCKED AND ATTRACT NANO PARTICLES OF CEMENT CONCRETE.
BOTH THE NANOCOAT AND CEMENT PARTICLES CURE SIMULTENIOUSLY WHICH IN DUE COURSE INCREASES BONDING STRENGTH TO 100% THAN UNCOATED REBAR. (When tested with M-35 concrete as per IS 2770 test at renowned labs). THIS EXTRA BONDING OF CONCRETE WITH NANOCOATED REBAR PREVENTS RUSTING IN FUTURE.
