| Application Method | Airless Spray Tip range 0.43 ~ 0.53 mm |
| Output pressure | 150 ~ 220 Kg / cm2 |
| Brush / Roller | For touching up small areas and stripe-coating |
| Mixing Ratio by Weight | BASE 88 / HARDENER 12 |
| Pot Life After Mixing | 6 hours (10℃) |
| 3 hours (20℃) | 2 hours (30℃) Since pot life is shortened at high temperature, avoid mixing excessive amounts at one time under such conditions. |
| Stripe Coating | Due to the high volume solids of the product, stripe coating to the full specified film thickness may be easily achieved in two applications. However, the correct technique as outlined below must be used: 1. The roller or brush should be fully charged with paint for each application. |
A roller shall be used for scallops, rat-holes etc., but not for edges and welds.
2. Light pressure on the tool will deposit more paint to the area - repeated heavy movements will tend to spread the paint more thinly and also aerate the paint - this should be avoided.
3. In the case of rough 'return welds' in scallops, the fully charged tool should be pulled into the weld and a 'side to side' motion employed to ensure that the cavities are fully coated.
4. Generally, stripe coating should only be necessary in areas that are difficult to coat by spray such as rough up-hand welds, return welds, free edges, scallops, drain holes, air holes, behind angles, stiffeners and brackets, etc.
Although NOA PC 700 exhibits very good flexibility properties over other epoxy products, it is 'good painting practice' not to over-apply coatings on welds that will be subject to stress. Stripe coating should also be avoided in areas where multiple passes by spray may be applied, such as corners or welds on right- angled structure.

Take precautions to avoid skin and eye contact (i.e. gloves, goggles, face masks, barrier creams etc.). Proper ventilation and protective measures must be provided during applications and drying to keep solvent vapour concentrations within safe limits. Prior to use, obtain, consult and follow the SDS for this product concerning health and safety information.
| 1) | The information contained in this sheet is liable to modification from time to time in light of experience and our policy of continuous product development. |
|---|---|
| 2) | Store the paints in paint store. |
| 3) | Discoloration (blackening ) may occur on the surface due to sulphide in cargoes. Its anti-corrosive performance is not adversely affected by the discoloration. |
| 4) | If half-dried painted surface is subjected to rain or dew, blooming or sweating may occur, with the surface turned to white. Rub the area lightly with a wire brush before painting. |
| 5) | For the applications, refer to our "Suitability Table of Cargoes for Loading" and "Application Procedure". |
| 6) | Paint application shall be done immediately after abrasive blasting. Small rusted parts, welding seam, burnt parts shall be thoroughly treated with power tool. |
| 7) | Max. interval depends on exposure condition of coating. To prevent coating from sun light, cover manholes etc. with awning and so on. In case that coating is exposed to sun light, Max (2) of interval shall be adopted. |
| 8) | Use products that comply with local regulations to clean the paint equipment. |
