Product Data

Basic data at 20°C (68°F)

Notes:

• Refer to tables below for information regarding spreading rate and film thickness, overcoating intervals and curing times

Recommended Substrate Conditions & Temperatures

Substrate conditions:

• Steel should be blast cleaned in situ to at least ISO-Sa2½
• Blasting profile 50 – 100 µm (2.0 – 4.0 mils)
• Steel must be free from rust, scale, shop primer and any other contamination
• Previous coat must be sound, dry and free from any contamination

Substrate Temperature & Application Conditions:

• Substrate temperature during application and curing should be above 10°C (50°F)
• Substrate temperature during application and curing should be at least 3°C (5°F) above dew point

System Specification

For use as a tank coating

• 2 coats of 150 microns (6mils) each, or 3 coats of 100  microns (4mils) each, to reach 300 microns (12 mils) total dry film thickness

Notes:

• For more information on min and max DFT see 'Explanation of Product Data Sheets' document in the DATA SHEETS tab
• On critical areas of a structure painted with PHENGUARD 985, 10% of the spot readings can be between 600 and 800µm. Individual gauge readings can be between 800 and 900µm. Critical areas are e.g. weld seams, edges, bolts, corners, nuts and areas of difficult access

Instructions For Use

Mixing ratio by volume: base to hardener 88:12

• The temperature of the paint 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

Allow induction time before use.

Spreading Rate and Overcoating Times

Spreading Rate and Film Thickness

Note: Maximum DFT when brushing: 150 µm (6.0 mils)

Overcoating Intervals

Notes:

• The performance of the applied system strongly depends on the curing degree of the first coat at the time of recoating. Therefore overcoating time between 1st and 2nd coat is extended in comparison between 2nd and 3rd coat (see overcoating details)
• When used as a primer under solvent-free tank linings the DFT must be limited to a maximum of 100 µm

Notes:

• The performance of the applied system strongly depends on the curing degree of the first coat at the time of recoating. Therefore overcoating time between 1st and 2nd coat is extended in comparison between 2nd and 3rd coat (see overcoating details)

Notes:

• Surface should be dry and free from any contamination

Curing Times and Pot Life

Curing Times:

Notes:

• Minimum curing time of before transport of cargoes with note 4, 7, 8 or 11: 3 months
• For detailed information on resistance and resistance notes, please refer to the latest issue of the cargo resistance list
• For transport of methanol and vinyl acetate monomer, a hot cure is required, which cannot be substituted by a service period of 3 months with non-aggressive cargoes
• Adequate ventilation must be maintained during application and curing (please refer to INFORMATION SHEETS 1433 and 1434)

Pot Life:

Safety Precautions

• 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
• See Safety Data Sheets for detailed information
