Surface Preparation

Recommended Substrate Conditions and Temperatures

Substrate conditions

Cargo tank should be in a clean, dry, gas-free condition prior to repairs
Previous coat must be dry and free from any contamination
Protection of applied coating in way of tread areas in the tank to be provided by mats; all personnel entering tanks to wear soft footwear
Minor rust areas and coating defects to be prepared by rotating disc or power tool cleaned to SPSS-Pt3 standard or by vacuum blasting to ISO-Sa2½ standard
Overlap areas of repair to be roughened by means of rough pads
Solvent wiping of prepared areas necessary to remove any cargo trace prior to application of the SIGMAGUARD 795
Substrate must be perfectly dry before and during application of SIGMAGUARD 795
After repair carriage of aggressive cargoes, with notes 4, 7, 8 or 11 will require a full cure e.g. 3 months service with nonaggressive cargoes or a hot cure

Substrate Temperature & Application Conditions

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

System Specification

Stripe coating: application of one coat of 75 µm (3.0 mils) preferably by brush
Touch-up and repairs: application in two even coats to total minimum DFT of 200 µm (8.0 mils)

Application

Instructions for Use

Mixing ratio by volume: base to hardener 85:15

The temperature of the mixed base and hardener should be above 10°C (50°F), otherwise extra thinner may be required to obtain application viscosity
If required, thinner should be added after mixing the components

Induction Time

None.

Brush/roller

Recommended thinner

THINNER 91-92

Volume of thinner

0 – 3%

Cleaning Solvent

90-53.

Spreading Rate and Film Thickness

DFT	Theoretical spreading rate
100 µm (4.0 mils)	7.5 m²/l (301 ft²/US gal)
150 µm (6.0 mils)	5.0 m²/l (201 ft²/US gal)

Overcoating interval for DFT up to 150 µm (6.0 mils)

Overcoating with...	Interval	10°C (50°F)	15°C (59°F)	20°C (68°F)	25°C (77°F)	30°C (86°F)	40°C (104°F)
Itself	Minimum	28 hours	20 hours	14 hours	8 hours	6 hours	4 hours
Itself	Maximum	28 days	25 days	21 days	17 days	14 days	7 days

Notes:

Cargoes should not be transported between the application of the subsequent coatings

Curing time for DFT up to 150 µm (6.0 mils)

Substrate temperature	Minimum curing time before transport of cargoes without note 4, 7, 8 or 11 and ballast water or tank test with sea water
10°C (50°F)	10 days
15°C (59°F)	6 days
20°C (68°F)	5 days
30°C (86°F)	3 days
40°C (104°F)	48 hours

Notes:

Minimum curing time before transport of cargoes with note 4,7,8 or 11: 3 months
Adequate ventilation must be maintained during application and curing (please refer to information sheets information sheet 1433 and Directives for Ventilation Practice (information sheet 1434)
Contact with water, within the curing period, will decrease the performance of the SIGMAGUARD 795 coating

Pot Life (at application viscosity)

Mixed product temperature	Pot life
10°C (50°F)	6 hours
20°C (68°F)	4 hours
30°C (86°F)	1.5 hours
40°C (104°F)	30 minutes

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
