ProTXcoat 390 FloorCoat
Floor Coat
High Build Epoxy Floor Coating
390 is a high performance solvent free ceramic reinforced heavy duty coating designed for use for long term floor protection.
390 is based on a unique blend of epoxy resins and polyamino amine adducts reinforced with a blend of inert pigments and inorganic ceramic particles to produce the optimum level of adhesion, abrasion, impact and chemical resistance which will provide excellent long term protection to industrial floors operating within aggressive environments.
390 is simple, safe and easy to use, provides a seamless easy to clean surface and is ideal for use in dairies, breweries, canteens, food factories, pharmaceutical plants and warehouses.
TECHNICAL SPECIFICATIONS
Surface preparation
All surfaces should be clean, dry and free from contaminants. Concrete surfaces should have all surface laitence removed by mechanical means e.g. light abrasive blasting or grinding, any resulting dust and debris should be swept away.
Non Porous Surfaces: Including tiled and power floated concrete should be primed with 302 Primer in accordance with the product tech sheet.
Porous Surfaces: Including concrete and mineral surfaces should be primed with 302 Primer in accordance with the product tech sheet. Rough and pitted concrete should be planed smooth and filled with 356 Screed then primed with 302 Primer in accordance with the product tech sheet.
Previously Coated Surfaces: Any loose/flaking material must be removed. Surfaces should then be thoroughly cleaned and abraded then primed with 302 Primer in accordance with the product tech sheet.
Metal surfaces: Should be abrasive blast cleaned, any resulting dust and debris should then be swept clean. Prepared surfaces can then be directly coated with 390.
Mixing
390 is a two component material comprising base and activator components which must be mixed together prior to use.
Stir the base component, continue stirring whilst adding all the contents of the activator component and mix until homogeneous. To ensure thorough mixing it is advisable that the mixed product is transferred to another container and the original container is scraped out, and further mixing carried out to ensure a homogeneous mix is obtained.
The mixed product must be used within 45 minutes of mixing at 20°C (68°F).
Applicaiton
390 should not be applied when the relative humidity exceeds 90% or when the surface to be coated is less than 3°C above the dew point. It is not advisable to apply 390 when the surface is less than 10°C (50°F).
390 can be applied by good quality brushes or medium pile rollers. The coating should be applied evenly with regular checks being made to ensure the correct film thickness is applied.
When application involves areas of an intricate nature it is advisable to split the mixed material into small quantities and use two applicators to avoid the material becoming unusable before application is complete.
Slip Deterrent System
To provide a slip deterrent system 390 should be mixed and applied as before to the primed surface. Whilst the coating is still wet the appropriate grade of Aluminium Oxide Aggregate 1mm can be scattered into the surface at approximately 25 gm (1 oz.) per square metre, to produce a medium density grip. After overnight curing any loose aggregate can be removed and if required a further seal coat of 390 can be applied.
Also Aluminium Oxide Aggregate 1mm can be stirred into the mixed 390 prior to application, and then applied by roller to provide a one coat slip deterrent finish.
Note: When tested to Clause 12.5 of BD29/87 in wet conditions a complete covering of Aluminium Oxide Aggregate 1mm produces an anti-slip factor of 99.4
