SOL

PSO-419A

Product Outline

Purpose For Exterior facade Self-cleaning use;
Appearance Semi-transparent, Opalescent
Characteristics Anatase TiO2 crystal content 9% dispersion ; Ethanol/ water dilution required; the samllest crystal grain size brings higher adherence with stronger Photocatalysis
Application Spraying and Room Temp curing / For Stainless steel, 200degC sintering; with over 500degC for higher hardness
Shelf life 6 months (for replaceable without opening; 3 year liquid duration)
Materials cost $1.90 – $3.52 USD/ m2 in Japan domestic market (Rate: $1.00USD=85 JPY)
Remarks
  • Higher temperature during brings higher adherence, but less relative surface area, which lowers down the hydrophilicity
  • At lower temperature curing, it may remain dispersion ingredients, which gives some chance that finished surface becomes brown
  • Alcohol dispersion brings faster dryness, and tendency for agglomeration, which makes it difficult for dip coating or glossy surface coating

Description

High adherence even at the room temperature dryness can be expected; which enables to apply for non-thermal resistible substrate such as cloth, paper, wood; needed protective layer primer coating: for thermal resistible ceramics, tile substrate, hardness with high adherence expected:

This is water based acidic dispersion sol, must be diluted for any use, impossible to apply without dilution:

Dilution must be started from 1:1 with Ethanol to make 4.5% concentration as the 1st stage, then afterwards it may be diluted with water as much concentration as demanded:

By adjusting the dilution rate, it is applicable to variety of the substrates, and it drys fast with alcohol content:

Because the original sol does not contain alcohol, it allows easiness for export shipping.

Caution for use

  • At the higher atmosphere temperature in summer, it is suggested not to apply while the surface temperature is too high: Because the alcohol evaporation urges the liquid dryness too quickly, which interrupts the liquid to level the film.
  • Diluted sol must be used as quick as possible to avoid the viscosity rise, and the agglomeration: diluted sol duration must be a few days after dilution.
  • At dilution, if only water is used to dilute, the final products loses the hydrophilicity; it must be used alcohol at the 1st stage dilution.
  • Dilution ratio and protocol are instructed at the purchase with a document.
  • Before start application, it is recommended to apply as a test at somewhere not noticeable.
  • It is requested to read and prepare with Materials Safety Data Sheet and Product specification which shall be handed at a purchase.
