Tetraguard W.B.

Description:

Tetraguard W.B. is a single pack catalysed polymer incorporating hollow thick-walled thermal beads. Tetraguard W.B. has been developed from outstanding technology.  This unique coating provides a permanent elastomeric flexible membrane coating designed to provide exceptional thermal and insulation properties on all types of substrates including; roofs, factories, galvanised iron, aluminium, steel, fibreglass, etc.

Features:

• 1mm filmbuild provides R Factor of 2.5
• 2mm filmbuild provides R Factor of 3.4
• Acoustic control
• Prevents condensation
• Sound proofing vehicles, boats, caravans
• All B.S. or designer colours
• Airconditioning cost lower

Uses:

All industrial and commercial areas that require thermal and condensation control.  Tetraguard W.B. Elastomeric Flexible Membrane has been developed for the long term insulation protection and weatherproofing of concrete buildings, hotels, shopping complexes, schools, hospitals, bungalows, housing, commercial buildings, galvanised iron roofs, steel, iron, bridges, waterproofing concrete, block buildings, storage tanks, freezing works, oil refineries, breweies, marine, automotive, cars, boats, caravans, steel, aluminium, etc.

Physical Properties:

Form	Acrylic Catalysed Polymer Thermal Beads
Flexibility	Elastomeric

 

Laboratory Trials - Tetraguard W.B. Insulated Coating:

A number of tests were carried out by our laboratory;

Test No.1	Standard 2 chamber heat transfer apparatus
Results:	Ambient in laboratory	25.6°C
Tetraguard W.B coated top chamber	26.7°C
Bottom chamber (heat source)	52.2°C
Test No.2	Standard 2 chamber heat transfer apparatus 24 hour run heat input 40 watts
Results:	Chamber (a) as for Test No.1 - Tetraguard @ 600 microns thickness
Chamber (b) lined with insulating batts (R2.5)
Variations above ambient:
Chamber (a) 1.1 to 1.6°C
Chamber (b) 2.0 to 3.0°C

 

The summary of these tests showed that the Tetraguard coating @ 600 microns had better insulation by 1°C to 2°C than the insulation batts.

Application to Steel, Fibreglass, Aluminium:

Primer:

Apply 1 coat of Tetracure P10 Primer @ 8-10 m2 per litre coverage (diluted 50% with Tetrasolve Solvent). Allow Tetraguard 30 minutes to cure.

Apply 2-3 coats of Tetraguard W.B @ 600 microns wet filmbuild per coat. Use as supplied and apply using pressure pot system intermitting each spray pass by 50% to achieve desired film thickness. For thermal insulation a minimum of 1mm should be achieved.

Coverage:

1.6m² per litre @ 600 microns W.F.B.

Dry Film Thickness:

300 microns per coat.

Dry Time:

Touch 60 minutes, Hard 8-24 hours

Recoat:

4-8 hours, depending on ambient temperature.

Application:	Brush, roller, pressure pot system, or airless spray - remove all in-line filters, use 26-28 thou tip
Clean Up:	Water or Brush Clean Solvent when dry
Thinning:	Do not Thin
Drying Times:	Tetraguard W.B. Elastomeric Flexible Membrane will dry and can be recoated after 2 hours at 20'C in cold or humid conditions.  Allow 8 hours before application of second coat.
Number of Coats:	Always apply 2 coats.  Plywood roof systems - 4 coats recommended with fibre mesh embedded.
Priming / Sealing:	Use correct Sealers on concrete and bibrolite.  Tetracure P10 Primers to be used on galvanised iron, steel and bridge structures, etc.  Always refer to preparation specification sheets before any application.
Preparation:	New and old concrete must be waterblasted and then Acid Etched.  apply appropriate Sealer.  Rust to be wire-brushed, then converted with Rid Rust Converter, then apply 2 coats of Tetracure P10 Primer.  Galvanised Iron to be cleaned with Chemocide Etch to remove oxidation, then primed with Tetracure P10
Packaging:	4 litre, 10 litre, 20 litre plastic pails
