ECI Application Guidelines
Application Guidelines for TIO2 Thin Films
1. Coating of substrates:
- Clean the surface of the substrate on which the coating is going to be applied. Avoid cleaning products containing ammonia as this can cause a disruption in the PH balance of OxiShield and OxiGuard.
- Clean the cup of the spray gun with pure (distilled) water prior to filling either with OxiShield or OxiGuard.
- Coating motion: The key is to finish evenly. Hold the gun steadily while moving the gun from left to right, ideally maintaining the distance from the nozzle to the surface of the substrate in a consistent manner while maintaining a smooth and consistent speed.
- It is recommended to apply both OxiShield and OxiGuard as thinly as possible for each pass. For best results it is recommended to apply both OxiShield and OxiGuard in two layers. Under normal conditions OxiShield will dry within a minute or two.
- Upon changing the solution from OxiShield to OxiGuard, make certain that the cup is rinsed thoroughly with pure (distilled) water.
- To visually inspect the evenness, view the coated surface from an oblique angle.
- Improving one’s skill of application of the coating requires practice. It is advisable to practice with water type ink, spraying on paperboard, glass and concrete block. Experience shows that the average painter/sprayer tends to apply the coatings in excess of recommended film requirements, as they are used to high viscosity liquids and therefore higher film build.
2. Curing:
It is recommended that the coating film be left for 8 hours untouched. The exposure to the sun light or to UV light will speed up the curing of the TiO2 film, strengthening the adhesion of primer to the substrate. Any variances in cure time, or set up time is fully dependent upon the skill of the applicator. All round-shaped or curved items are always difficult surfaces for even coating. Care should be taken to apply coatings as evenly as possible.
3. Standard consumption rate of solution:
OxiShield: 10 gr/m2
OxiGuard: 7gr/m2
This consumption rate is the norm for coating over a painted surface. For bare concrete, ceramic tiles, or porous materials, the rate of the consumption is naturally higher than the above stated coverage rates.
