 Astro-DecŪ is a coating which is applied by brush, roller or spray applicators to the roof of the building or structure etc. and also to the walls, where necessary, for the purpose of cooling the building or structure dramatically.

Air temperatures measured inside buildings can drop by up to 15 degrees centigrade and temperatures of roof sheets or walls can drop by up to 30 degrees centigrade.

This exceptional thermal insulating coating is the very best available and encompasses the most modern approach to this technology utilizing an advanced  metalic, string oxidised, sulphonation complex to achieve it`s extraordinary properties.

Astro-DecŪ shows excellent resistance to rust show through, leaves a gloss smooth finish to the substrate.

 Astro-DecŪ has superior adhesion propensity, better opacity, extended coverage, higher cooling capacity and is also chip blister, crack and peel resistant and displays excellent rust fighting capabilities.

 Astro-DecŪ is a liquid paint-like coating, radiation barrier, highly effective as reflector of radiation and a good thermal non-conductor (insulator) due to advanced technology employed and confirmed by SABS tests.

 Astro-DecŪ is an exciting new development in paint or coating technology. The product is solvent based and consists of a coating containing a mixture of state of the art hi-tech  particles.

Astro-DecŪ retains less dirt and is easier to keep Clean.

 Astro-DecŪ can be applied by brush, roller or spray applicators. It is unaffected by ultra violet light, is acid resistant, waterproof, hard wearing, long lasting, flexible, impact resistant, etc.

 Astro-DecŪ can be applied to ANY surface including galvanized iron without the necessity for an undercoat. (Although an undercoat from Cosmo-Dec is strongly recommended )

 Astro-DecŪ has a wide variety of applications including factory and house roofs, poultry houses, pig sties, warehouses and shops.

 Astro-DecŪ when used by the fresh fruit and vegetable industry helps to significantly reduce inside  storage temperatures, thereby prolonging shelf life which translates into huge financial savings.

 Astro-DecŪ is a one pack system i.e. pre-mixed coating which has a prolonged shelf life. When applied outside in dry weather, the drying time will be no more than 30 minutes to the touch.

Uses

 

ADVANTAGES

 

 Astro-DecŪ applied to flat concrete roofs helps to prevent thermal shock here, to a remarkable degree thus putting an end to expansion and contraction of these structures which in turn prevents these roofs from cracking and leaking which is a feature of these types of structures. Architects, builders engineers etc. often go to enormous lengths  at great expense to achieve similar results on flat concrete roofs to what a simple application of  Astro-Dec will.

In-Situ applications, no need to stop production or interfere in any way with on going activities in order to apply  Astro-DecŪ, Quiet interference free applications ensure this, no fumes, no problems! 

 

Cosmo-Dec`s hi tech approach to it`s coating technology means we are always at the forefront when it comes to new innovative ideas.

Our coatings contain active ingredients that literally clean the air.

With  Semi conductor low temperature  nano absorption - SLANT-  technology we modify our paint to interact with pollutants in the atmosphere rendering them  as inert

salts.

 

 

  Surface preparation

The substrate should be clean dry and stable.

 

Application: Ensure that the surface is free of loose paint, dirt, grease, grime etc. and that it is dry prior to applying  Astro-DecŪ. Apply by brush roller or spray applicators

When used in conjunction with Dead-End  Astro-DecŪ achieves a 100% adhesion

as tested by SABS.

Coverage : 4 to 5 square metres per litre depending on the substrate and method of application.

Colour :   Astro-DecŪ is available in most light colours

 

Technical Information

SABS TESTS CONDUCTED AND RESULTS OBTAINED

Thermal Insulation Coating.

Test report 7222/ 2090038/v 76

Product was tested for: 

Heat absorption of air inside treated  and non-treated containers.

Adhesion of thermal coating.

Test methods:

Adhesion - requirements in accordance with SABS ISO 2409 : 1992

Two containers - one coated one non-coated.

Inside temperatures measured with thermocouple at 1 hour intervals

Between 11:00 and 15:00.

Test window:

12 April 2002

Results:

Adhesion - 100 % adhesion, no loss.

Inside Temp - Temp in coated container is always lower than uncoated by approx. 18%.

As ambient temp. drops air in coated container drops slower than uncoated container confirming insulating properties

Air Conditioning FAQ

Costs are in AUS$

Multiply by 7 for ZAR

 

 

 

Use a rule of thumb of about 600 Btu per square meter of floor area to be air conditioned

 

 

9000 Btu of cooling output equates to 2.64 Kw of cooling wattage which requires 1000 watts of electrical input which will cost about R0.75 cents per hour.

 

 

The above electrical consumption costs don`t take into account maintenance or initial installation costs which can increase the above savings by a factor of 3

 

 

1 Kg of air is about 850 liters in volume

 

 

The specific heat capacity of air is about 1 -  i.e it requires about 1 KJ to  heat 1 Kg of air by 1 deg.C

 

 

1 KJ is approx. .95 BTU
