POT LIFE

Product temperature	Pot life
20°C [68°F]	60 min

---

APPLICATION METHOD

Tool	Application parameters
Airless spray	Nozzle pressure: 250 bar [3600 psi]
	Nozzle orifice: 0.019–0.031″

If brush or roller application is used, more coats will be necessary to achieve the specified dry film thickness. As tank lining, brush and roller application must only be limited to stripe coating and touch up areas or minor repairs. Spray data are indicative and subject to adjustment. Pressure is for a material temperature of 20°C [68°F].

FILM THICKNESS

Specification range	Low	High	Recommended
Dry film thickness	200 micron [8.0 mils]	300 micron [12 mils]	300 micron [12 mils]
Wet film thickness	200 micron [8.0 mils]	300 micron [12 mils]	300 micron [12 mils]
Theoretical spreading rate	5 m²/L [204 sq ft/US gal]	3.3 m²/L [134 sq ft/US gal]	3.3 m²/L [134 sq ft/US gal]

---

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 10°C [50°F] during application and curing
• Temperature of product must be above 15°C [59°F] during application
• Relative humidity must be below 85% during application and curing

DRYING AND OVERCOATING

Product compatibility

• Previous coat: None or according to Hempel’s specification
• Subsequent coat: None or according to Hempel’s specification

Drying time

Surface temperature	Touch dry	Hard dry	Fully cured
20°C [68°F]	6 hours	15 hours	7 days

Determined for dry film thickness 300 micron [12 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]	40°C [104°F]
Hempadur Multi-Strength 35535	Min: 40 h	Min: 16 h	Min: 8 h	Min: 5 h
	Max: 12 d	Max: 5 d	Max: 60 h	Max: 36 h

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.

---

OVERCOATING DETAILS

• If the maximum overcoating interval is exceeded, roughening of the surface is necessary to ensure intercoat adhesion.
• The surface must be clean before overcoating.
• As tank lining, if the maximum overcoating interval is exceeded, roughening of the surface by sweep abrasive blasting is necessary to ensure intercoat adhesion.

STORAGE

Shelf life

Ambient temperature	Base	Curing Agent
25°C [77°F]	36 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.

CARBON FOOTPRINT

Dry film thickness	1 µm	1 mil
GWP	7 g CO₂e/m²	0.036 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.
