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.

Description

PPG SigmaWeld 120 is a two-component, polyamide-cured epoxy prefabrication primer that is suitable for automatic application on shot blasted steel plates.

Top Features & Benefits

Good cutting and welding properties, including MMA and gravity welding
Provides corrosion protection up to 6 months, when applied at a DFT of 22 µm (0.9 mils) (depending on exposure conditions and blasting profile)
Fast-drying properties
Can be used as a first coat in various paint systems for atmospheric exposure conditions only
Flat finish

Preparation & Application

Recommended Substrate Conditions and Temperatures

Substrate Conditions

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

Substrate Temperature

Substrate temperature during application and curing should be at least 3°C (5°F) above dew point
Substrate temperature during automatic application should be between 35°C (95°F) and 40°C (104°F)

Secondary Surface Preparation

During storage and construction, contamination of the prefabrication primer should be limited. After fabrication, surface defects should be treated according to the scheme hereafter.

Instructions for Use

Mixing ratio by volume: base to hardener 75:25 (3:1). The temperature of the mixed base and hardener should preferably be above 15°C (59°F). Strain mixture through a 30 – 60 mesh screen. Mixed paint is ready for use.

Some addition of thinner (THINNER 90-53) might be necessary depending on routing, line speed and steel temperature. Agitate continuously during application.

Pot Life

24 hours at 20°C (68°F)

Air Spray

Recommended thinner: PPG Thinner 90-53

Volume of thinner: 0 - 5%, depending on required thickness and application conditions

Nozzle orifice: 1.0 - 1.5 mm (approx. 0.040 - 0.060 in)

Nozzle pressure: 0.15 - 0.20 MPa (approx. 2 - 2 bar; 22 - 29 p.s.i.)

Airless Spray

Recommended thinner: PPG Thinner 90-53

Volume of thinner: 0 - 5%, depending on required thickness and application conditions

Nozzle orifice: Approx. 0.43 - 0.58 mm (0.017 - 0.023 in)

Nozzle pressure: 12.0 - 15.0 MPa (approx. 120 - 150 bar; 1741 - 2176 p.s.i.)

Cleaning Solvent

PPG Thinner 90-53

Safety Precautions

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. For paint and recommended thinners see INFORMATION SHEETS 1430, 1431 and relevant Material Safety Data Sheets.
