 Wet the rusted surface with coating liquid and it will be penetrated into porous air hole on the rust and coated materials and then self-hardening. It forms internal bonding structure between porous air hole and coating liquid.  Coating materials is specific Metallic Chemicals and becomes part of substrate on the rusted surface of materials like electronic plating. This is not the same coating materials as the general anti-corrosion coating materials  The polymer of coating liquid is penetrated into porous air hole of surface and then absorb the humidity of atmosphere to generate gas and make micro expansion of porous air hole. It is hardened and play role of bonding and locking between coating materials and surface.  Metallic forms air encapsulation on the surface of coated materials and paint together with polymer. It protects modification by ultraviolet ray  This can be used alone and independently or used as substrate coating. It can be applied directly to the rusted surface and forms air encapsulation on the surface to protect rust improvement or transferring Ⅶ. Principle of Coating

1. Surface Treatment :  For the superior adhesion and getting rid of the coated defects, all rust scale, dust, dirt, oil contaminants on the surface should be removed completely  The rust scale must be removed by scratching and surface of coating materials must be dried  If NT-100 is coated on the surface of water contained materials, the hardening of coating liquid can be started before air encapsulation is started by penetrating into metal or porous air hole of surface, and the adhesion power can be reduced. 2. Coating Condition:  Coating must be done over at 0 ℃ over and the optimum temperature for coating is 10 ℃ ~38 ℃ 3. Mixing Rate :  This is single liquid type and can be used alone without hardening materials and Bottom coating can be used independently without middle coating and upper coating. 4. Coating Method:  Airless Spray Gun, Bush, and roller 5. Diluting Solution  MEK, MIBK Ⅷ. Coating Method

6. Paint and Coating Materials Preparation:  Metallic Components contained in NT-100 can be sink down at the bottom.  Fully shaking is needed before coating or use low speed stirrer  As NT-100 absorbs humidity of atmosphere and hardened, the lid should be closed after taking out quantity.  If the surface of NT-100 liquid in the used can is hardened, you can break the hardened surface and stir and mix to use 7. Coating Procedures :  NT-100 needs always two times of coating to fill up micro hole generated after 1 st coating and at the same time, increase coating thickness for the endurance of coating  For the very high thickness of coating, the 2 nd coating should be made by NT-100(HS)  2 nd Coating should be made within 4-6 hours after 1 st coating. 2 nd Coating cannot be adhesive to the 1 st coating surface 8. Hardening Time :  If one hour is passed after coating, the paint is not wet on the hand but for the complete hardening, it takes days. 9. Keeping and Storage:  Lid of the can should be closed when the paint is not used. Never keep the lid open over 4 hours.  The can of 2 liters is recommendable to keep and store the paint on the shelf after opening the can Ⅷ -1. Coating Method
