Joma CLEAN

Self-cleaning concrete treatment

Joma CLEAN gives photocatalytic self-cleaning power to concrete and stones, helping prevent growth of organisms such as algae, mold and bacteria.

Joma CLEAN is non-hazardous, has long shelf life, and can be easily sprayed onto clean concrete or stone surfaces. The nanoparticles diffuse into the pores of the material and bind to the material, making a durable structure with a highly active surface..

When exposed to ultraviolet (UV) rays present in natural sunlight, the active nanomaterial produce radicals that attack microorganisms, but without being consumed themselves. The same radicals also destroy toxic NOx gases and other air pollution. Independent 3rd party testing (ISO 22197) of this Joma product applied on paving stones has shown a record high activity.

TiO2 nanoparticles make the surface to which it is applied more hydrophilic, which may give an extra ‘easy-clean’ effect by allowing water to penetrate further underneath particles stuck to the surface.

FEATURES

  • ·         Photocatalytic + hydrophilic surface
  • ·         Easy to apply by spraying or brushing
  • ·         Extremely diffusion open
  • ·         Non-hazardous, pH 8-9
  • ·         Recommended for: concrete paving stones, bricks and roof tiles.
  • ·         Also suitable for: natural stones or as overcoat on silicate/inorganic paint.
  • ·         One liter covers approx. 10 m2 depending on surface porosity
  • ·         Concentrated version available for mixing into formulations.

 

* This product is not recommended for coating onto emulsion paints or plastics or other organic substrates. Application on surfaces already treated with other coatings or sealants may give variable results. Consult Joma to find out the best combination for your needs

Joma TITAN-T series for textile coatings

 

The TITAN-T series is a range of custom formulations for treatment of textiles and plastics. Coated outdoor textiles such as tents and awnings show anti-biofilm properties which preserves appearance, reduces maintenance and increases the effective lifetime. Indoor textiles such as microfibres cloths can be treated to obtain anti-microbial properties, and Joma is currently involved in a multinational research project to assess the potential for such cloths in hospital wards.

The TITAN-T formulation can be modified so that the photocatalytic property does not replace other valuable surface properties such as superhydrophobicity, but complements it.

The TITAN-T series is currently available only at small scale or via development agreements. Please contact us for further information.

Joma TITAN-G series

 

The TITAN-G series is a range of custom dispersions of Joma TiO2 nanoparticles suitable for coating onto glass or ceramic tiles where transparancy and visual appearance are of high importance.

The TITAN-G series is currently available only at small scale or as production prototypes.

Please contact us for further information.

Paint pre-formulations and powders


Joma has developed customised formulations of active particles suitable for mixing into paints, particularly suited for non-organic paints. Our internal prototype paints obtain NOx abatement rates (by ISO 22197) far surpassing those of products available on the market. The formulations have to be customized for each paint manufacturers’ specific ingredient mix.

Please contact us if you have interest in developing a photocatalytic paint.

Self-cleaning concrete and stones

 

Joma offers a choice of formulations for concrete and stones:

  • Joma CLEAN impregnates active nanoparticles into the surface pores, giving top photocatalyitic performance with minimal effect on other properties. This is recommended for de-NOx and other anti-pollution applications.
  • Joma PROTECT combines the same active material with a hydrophobising surface, thus combining the two major self-cleaning mechanisms. This is recommended for anti-biofilm applications.
  • Joma PROTECT White is a variant of the PROTECT product specialized for natural and light colored concrete.

Joma CLEAN

The Joma CLEAN series is a range of custom dispersion developed for treating paving stones and other concrete structures, but can also be used to protect natural or worked stone.The CLEAN product applied to generic commercial paving stones has been measured by 3rd parties to have record high de-NOx abatement under ISO 22197 standard test conditions.

The products are mildly basic and non-hazardous.

 

Joma PROTECT

The PROTECT series has the same high activity nanoparticles, but in a formulation that also hydrophobises the surface. This combines active photocalatysis with the passive 'lotus effect', making it very hard for biofilm to accumulate. The PROTECT formulation is suitable for a wide range of concretes and natural stones, but treated surfaces should always be tested for compatibility first. See also PROTECT White for natural untreated or light colored concrete.

This product is corrosive (basic) and must be treated as dangerous goods.

 

Joma PROTECT White

This is a PROTECT White series product optimised for natural grey concrete or cement. It is non-hazardous and safe to work with and gives the best results on natural concrete, but is less suitable for other types of surfaces.

This product is pH neutral and non-hazardous.
