Search ID PPG4145

PPG SigmaCover 522 is a two-component, micaceous iron oxide-pigmented, polyamide-cured epoxy primer/sealer/coating. It has excellent adhesion to, and sealing of, weathered, cleaned, zinc-rich primers and metal-sprayed steel, with good adhesion to properly pre-treated galvanized steel.

Can be used in systems for atmospheric or water-immersed exposure conditions, with good resistance to industrial - or chemical-contaminated atmospheric exposure conditions
Good abrasion and impact resistance - Prevents Corrosion Under Insulation (CUI)
Pass cryogenic cyclic test from -196°C (-321°F) to 140°C (284°F)
Resistant to temperatures up to 200°C (390°F) in dry atmospheric exposure conditions
No induction time - 8 hours pot life - Touch dry in 2 hours - Fully cured after 7 days

ColourPicker Explained

In general we sort colours for products into 2 main groups - ‘Ready Mixed’ and ‘Tinted’.
Tinted colours will always be more expensive than Ready Mixed colours as they need to be produced at the time of order using a tinting machine dispensing colourant into a base*.
During busy periods, this means that tinted colours could take longer, for example – a ready mixed colour ordered on a 3-5 day delivery might arrive within 3 days, however a tinted colour might take the full 5 days to arrive.

To find Ready Mixed colours, search "ready mixed" or select the Ready Mixed 'colour chart'. To see Tinted colours select a colour chart such as RAL, BS, NCS, etc. or search for a colour/hue to see available or related options.

To ensure fair pricing, we split colours into ‘Price Bands’ to group together similar priced colours. If you wish to search for the cheapest tinted colours, always select Price Band 1.

We make every effort to list all available colours, however we also offer a colour match service which can be accessed by contacting our Technical Team on 0113 245 5450 (option 2) or emailing [email protected]

*Colours are sold in the nearest tin size but actual paint volume per tin may vary up to 10% depending on colour

Colour reproduction of the Products on the Site is limited by the technology used to deliver web pages and by the colour representation of Customer’s own monitor and computer set-up. We have made every effort to display as accurately as possible the colours of our Products but we cannot guarantee that the colour shown on Customer’s monitor’s display will accurately reflect the colour of the Product on delivery. We recommend that Customer first purchases the smallest Product available or access an industry standard colour chart in person (and not digitally) to ensure that the colour is acceptable for its purposes.

Surface Preparation

Recommended Substrate Conditions and Temperatures

Substrate conditions

Steel;

Blast cleaned to ISO-Sa2½, blasting profile 40 – 70 µm (1.6 – 2.8 mils)

Shop primed steel;

Sweep blasted to SPSS-Ss or power tool cleaned to SPSS-Pt3

Zinc rich epoxies and zinc silicates must be dry and free from any contamination
Galvanized steel;

For atmospheric exposure conditions disc sanding, and for water immersed exposure conditions sweep blasting is required

Stainless steel, non-ferrous metal should be sufficiently roughened by light sanding
Compatible previous coat must be dry and free from any contamination
When used as an adhesion primer or when a long overcoating interval is expected a maximum DFT of 50 µm (2.0 mils) must be specified in order to preserve the rough texture

Substrate Temperature & Application Conditions

Substrate temperature during application and curing should be above 10°C (50°F)
Ambient temperature during application at 5°C (41°F) is acceptable; however curing to hardness takes longer and complete cure will be reached when the temperature increases
Substrate temperature during application and curing should be at least 3°C (5°F) above dew point

Application

Instructions for Use

Mixing ratio by volume: base to hardener 82:18

The temperature of the mixed base and hardener should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity
Adding too much thinner results in reduced sag resistance
Thinner should be added after mixing the components

Induction Time

None.

Pot life

8 hours at 20°C (68°F)

Refer below for more information

Notes:

Surface should be dry and free from any contamination
The minimum overcoating time should be multiplied by 5 when SIGMACOVER 522 is to be applied on top of an existing old (alkyd) primer or coating
Surface should be properly cleaned
Glossy finishes require a corresponding undercoat

Curing time for DFT up to 100 μm (4.0 mils)

Substrate temperature	Dry to touch	Dry to Handle	Full Cure
5°C (41°F)	8 hours	18 hours	N/A

20°C (68°F)	2 hours	4 hours	7 days
25°C (77°F)	1.5 hours	4 hours	5 days

Notes:

Adequate ventilation must be maintained during application and curing (please refer to information sheets 1433 and (1434)
For optimum resistance in tank coating systems a minimum substrate temperature of 10°C (50°F) is essential

Pot Life (at application viscosity)

Safety Precautions

For paint and recommended thinners, see information sheets information sheet 1430, information sheet 1431 and the relevant Material Safety Data Sheets in the attachments section above
This is a solvent-borne paint and care should be taken to avoid inhalation of spray mist or vapor, as well as contact between the wet paint and exposed skin or eyes
