Product characteristics

Recommended use

Hempatop Direct 700 is recommended as a low VOC, very fast curing, high-build enamel for protection of structural steel in medium to severely corrosive atmospheric environments.
In mild to medium corrosive environments, Hempatop Direct 700 can be used for one-coat direct-to-metal applications. In severely corrosive atmospheric environments, Hempatop Direct 700 can be applied either on zinc metallized surfaces or in two-coat systems primed with zinc epoxy, such as Hempel’s Avantguard products.

Product may be specified in another film thickness than indicated depending on purpose and area of use. This will alter spreading rate, drying and curing time and overcoating interval. For best performance, avoid excessive film thickness.

---

Application conditions

• To avoid condensation, apply on a clean and dry surface with a temperature that is at least 3°C [5°F] above the dew point.
• Surface temperature must be above 0°C [32°F] during application and curing.
• Temperature of product must be above 15°C [59°F] during application.

30°C [86°F]	15	30

Determined for dry film thickness 200 micron [8.0 mils] at standard conditions, see Hempel’s Explanatory Notes for details.

Overcoating

Hempel’s specification supersedes any guidelines indicated in the overcoating table

Quality name	10°C [50°F]	20°C [68°F]	30°C [86°F]
Atmospheric severe
Hempatop Direct 700
Min	2 h	60 min	30 min
Max	60 d	30 d	15 d

Overcoating times are indicative for products of the same generic chemistry. Consult Hempel’s specification for more information.

---

Drying conditions

• To obtain the drying time stated, it is important to maintain sufficient ventilation during application, drying and curing.
• Condensation on the freshly applied coating should be avoided.

Overcoating details

• If the maximum overcoating interval is exceeded, roughening of the surface is necessary to ensure intercoat adhesion.
• The surface must be dry and clean prior to application.

Other remarks

• Hempel’s Specification supersedes any recommendations given in the Product Data Sheets.

Storage

Shelf life

Ambient temperature	Base	Curing Agent
25°C [77°F]	12 months	24 months

Shelf life from date of production, when stored in original, unopened containers. Thereafter, the product quality must be re-inspected.
Storage at elevated temperatures may reduce shelf life. For advice, please consult Hempel.

Storage conditions

• The curing agent is sensitive to moisture. Store in a dry place and keep the can tightly closed until use.

Carbon Footprint

Dry film thickness	1 µm	1 mil
GWP (Global Warming Potential)	6.3 g CO₂e/m²	0.033 lb CO₂e/ft²

The carbon footprint is for 1 square meter / square foot of surface area with a dry film thickness of 1 micron / mil.

The scope includes raw materials, in-bound transport to the Hempel factory, Hempel manufacturing processes, and any Volatile Organic Compounds emitted during and after the application of the product.

It is calculated based on the standard shade defined in this PDS.
Values may vary with shade.
