Thermal insulation & water-proof coating Metashield

A. INTRODUCTION

MetaShield Insulation and Water-proof Paint is produced under American technology from vacuum microspheres which has very low thermal conductivity. MetaShield enables you to deal with water-proofing and thermal insulation at the same time with the durability under all weather conditions.

B. APPLICATION AREAS

MetaShield can be used for thermal insulation and water-proof purpose on:

  • Metal or brick roof, concrete wall, terrace,… of: dwelling house, factory, school, hospital, department store, warehouse, hotel, gymnasium, iron sheet house, container house and wooden house…
  • Water storage tank, oil storage tank, oil field, animal industry, cold storage house, oil pipe and insulating pipe…
  • Bus, small bus, water-craft, vending machine…
  • Heating, Ventilation and Air Conditioning (HVAC) systems.

C. METASHIELD BENEFITS

  • Very low thermal conductivity which provides efficient thermal insulation capacity.
  • Excellent water-proof which protects roof and wall under all weather.
  • Play role as a good sealant to the rooftops.
  • Protect rooftops out of damage thanks to chemical resistance.
  • Dry coating film with high hardness feature and dirt pick up resistance.
  • Good washability.
  • Sound damping when raining.
  • Good bonding to almost surfaces: concrete, metal, wood…
  • Lightweight coating, not affect to the load of structure.
  • Water based, environmental friendly.
  • No heavy metals and hazardous substances.
  • Durability under all climates, including coastals.
  • All applying methods can be used: brush, roller or spray.
  • Coating application does not affect activities inside.

D. HEAT INSULATING EFFICIENCE

Note:

  • The temperature is measured in common industrial workshop conditions
  • Dry film thickness = 0.3mm

F. COATING INSTRUCTION

Surface preparation

Metal roof

þ  Remove any loose matter.

þ  Clean dirt, dust, oil and mould with water.

þ  Fix hole or crack with compatible paste, sealant.

þ  If surface is heavy rust, apply anti-rust Primer RS before apply InsuMax coating.

þ  If surface is new, use a light vinagar with water to washout oil and protective compound from the surface.
Concrete wall

§  Old wall

þ  Remove loose matter.

þ  Fix hole or crack with compatible mastic.

§  New wall

þ  Let the concrete wall completely cured and dried. (Normally concrete curing time 20 days)

þ  Applying suitable mastic when needed. Sanding by sand paper.

MetaShield preparation

  • Stir the paint thoroughly.
  • Dilute with water if needed but not exceed 5%.

Coating

  • Brush, roller or air spray.
  • First layer: thin (less than 150 micron).
  • Second layer: thick, followed the first dried layer, (normally 1 hour in sunny day).
  • 2.33m2 coated per one liter, equivalent to dry film thickness of 300 microns.
  • Notice: area of corrugated is always larger than plan (flat), so actual coating area = corrugated iron profile x extended coefficient.

Tool cleaning

  • Empty hose and nozzle, fill with water and spray until clean.
  • Use up remaining paint on roller or brush, wash completely. For the next use, soak roller or brush in water to prevent from drying.

G. STORAGE

  • First in – first out basis (FIFO).
  • Keep container closed while not in use.
  • Store in dry and well ventilated condition, avoid direct sunlight.
  • Keep out of reach of children.
  • Shelf-life: 36 months.

H. PACKING

  • 17 liter pail
  • 5 liter pail

I. ENVIRONMENT & HEALTH SAFETY

  • Non-hazardous components to the environment and health.
  • Product is non-flammable and non-explosive.
