Safety:
Handle with care. Before and during use, observe all safety labels on packaging and paint containers,consult HEMPEL Safety Data Sheets and follow all local or national safety regulations.

SURFACE PREPARATION:
Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning.
Abrasive blasting to Sa 2? (ISO 8501-1:2007), SSPC-SP 10/ NACE No. 2, with a sharp-edged surface profile corresponding to Rugotest No. 3, BN10a-b, Keane-Tator Comparator, 3.0 G/S, 2-3 S, or ISO Comparator, Medium (G).

APPLICATION CONDITIONS:
Use only where application and curing can proceed at temperatures above: -10°C/14°F. The temperature of the surface must also be above these limits. The temperature of paint itself should be 15°C/59°F or above. Apply only on a dry and clean surface with a temperature above the dew point to avoid condensation.
In confined spaces provide adequate ventilation during application and drying.

SUBSEQUENT COAT:
According to specification.

REMARKS:
Note:
If used as anticorrosive protection under insulation of high temperature equipment it is very important that NO moisture can penetrate during slow-down periods. This is to avoid the risk of "wet corrosion" when the temperature rises.

Weathering/service temperatures:
The natural tendency of epoxy coatings to chalk in outdoor exposure and to become more sensitive to mechanical damage and chemical exposure at elevated temperatures is also reflected in this product.

Stirring:
Before mixing with the curing agent stir the base thoroughly in order to redisperse any possible settling after storage. After mixing it is equally important to maintain stirring to keep the wet paint as a homogeneous mixture.
This is specifically important in case of a high level of thinning and/or long break in application, where the risk of settlement of zinc particles is the highest.

Film thicknesses/thinning:
May be specified in another film thickness than indicated depending on purpose and area of use. This will alter spreading rate and may influence drying time and overcoating interval. Normal range dry is:40-80 micron/1.6-3.2 mils. Thicknesses down to 15 micron/0.6 mils (extra thinning) and up to 80 micron/3.2 mils may be possible. This will alter spreading rate and may influence amount of thinning necessary, drying time, and recoating interval.
(The dry film thickness range does not take into account the correction factors for rough surfaces as listed in ISO 19840).

Overcoating:
Overcoating intervals related to later conditions of exposure: If the maximum overcoating interval is exceeded, roughening of the surface is necessary to ensure intercoat adhesion.
Before overcoating after exposure in contaminated environment, clean the surface thoroughly with high pressure fresh water hosing and allow drying.

Overcoating note:
*Depending on actual local conditions, the long maximum overcoating intervals may vary.
Contact HEMPEL for more information.
A completely clean surface is mandatory to ensure intercoat adhesion, especially at long overcoating intervals. Any dirt, oil, grease, and other foreign matter must be removed with suitable detergent followed by (high pressure) fresh water cleaning. Salts to be removed by fresh water hosing. In addition,scrubbing with a stiff brush may be necessary to remove zinc corrosion products (white rust). If themaximum overcoating interval is exceeded, roughening of the surface is necessary to ensure intercoat adhesion.
