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

Previous coat must be dry and free from any contamination

Substrate Temperature & Application Conditions

Substrate temperature during application and curing should be above -5°C (23°F)
Substrate temperature during application and curing down to -5°C (23°F) is acceptable; provided the substrate is free from ice and dry
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 86:14

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 and slower cure
Thinner should be added after mixing the components

Induction Time

Mixed Product Induction Time
Mixed Product Temperature	Induction time
Below 10°C (50°F)	15 minutes

Pot life

4 hours at 20°C (68°F)

30°C (86°F)	18 hours	5 days

Notes:

Adequate ventilation must be maintained during application and curing (please refer to information sheets 1433 and 1434)
In exceptional cases SIGMACOVER 555 may be applied at lower substrate temperatures (down to -15°C (5°F)) provided that the surface is free from ice and other contamination. In such cases special care must be taken to avoid thick film application as this may lead to checking/crazing or solvent entrapment. It should be clear that application at lower temperatures will require additional thinning to obtain application viscosity, however this will affect the sag resistance of the applied coating and can induce solvent retention. Optimal curing and designed product properties will only be achieved when minimum required substrate temperature is reached

Pot Life (at application viscosity)

Mixed product temperature	Pot life
5°C (41°F)	8 hours
10°C (50°F)	6 hours
20°C (68°F)	4 hours
30°C (86°F)	2 hours

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 vapour, as well as contact between the wet paint and exposed skin or eyes
