HEMPADUR MASTIC 45880
BASE:45889
CURING AGENT:95880

Description:
HEMPADUR MASTIC 45880 is a two-component polyamide adduct cured, high solids, high build epoxy
paint. It forms a hard and tough coating, has good wetting properties and low temperature curing.

Recommended use:
paint systems where low VOC and high film build are required.
For immersed areas HEMPADUR MASTIC 45880 is only recommended for minor repairs.
Can be specified where extended recoating properties for polyurethane topcoats are requested
(typically travel coating). May be used directly on cured zinc silicate (GALVOSIL products) or spraymetallized
surfaces to minimize popping.

Service temperature:
Maximum, dry exposure only: 120°C/248°F.

Certificates/Approvals:
In accordance with Aramco’s specification APCS 1, APCS 12, APCS 26 and 26T.
Tested according to section 175.300 of the Code of Federal Regulations Title 21 - Dry Foodstuff.
Consult Hempel for details.
Complies with European Fire Standard EN 13501-1; classification B-s1, d0.
Tested for non-contamination of grain cargo at the Newcastle Occupational Health & Hygiene, Great
Britain.
Approved as a low flame spread material when used as part of a predefined paint system. Please refer
to “Declaration of Conformity” on www.Hempel.com for further details.

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:
New steel: Abrasive blasting to minimum Sa 2? (ISO 8501-1:2007) with a surface profile
corresponding to Rugotest No. 3, N9a to N10, preferably BN9a to BN10, Keane-Tator Comparator, 2.0
G/S or ISO Comparator, Medium (G).
Zinc silicate painted or spray-metallized surfaces: Remove oil and grease, etc. with suitable
detergent. Remove salt and other contaminants by (high pressure) fresh water cleaning. Zinc salts
(white rust) must be removed by high pressure hosing combined with rubbing with a stiff nylon brush if
necessary. It is recommended to recoat spray-metallized surfaces as soon as possible to avoid
possible contamination.
Concrete: Remove slip agent and other possible contaminants by emulsion washing followed by high
pressure hosing with fresh water. Remove scum layer and loose matter to a hard, rough and uniform
surface, preferably by abrasive blasting, possibly by other mechanical treatment or acid etching. Seal
surface with suitable sealer, as per relevant painting specification.
Repair and maintenance: Remove oil and grease etc. thoroughly with suitable detergent. Remove
salts and other contaminants by high pressure fresh water cleaning. Clean damaged areas thoroughly
by power tool cleaning to minimum St 2 (spot-repairs) or by abrasive blasting to min. Sa 2, preferably to
Sa 2? (ISO 8501-1:1988). Improved surface preparation will improve the performance of the product.
As an alternative to dry cleaning, water jetting to sound, well adhering coat and/or to steel. Intact coat
must appear with roughened surface after the water jetting. By water jetting to steel, cleanliness shall
be: Wa 2 -Wa 2? (atmospheric exposure) / minimum Wa 2? (immersion) (ISO 8501-4:2006).
Acceptable flash-rust degree before application: maximum M (atmospheric exposure) / M, preferably L
(immersion) (ISO 8501-4:2006).
Feather edges to sound and intact areas. Dust off residues. Touch up to full film thickness. On pitcorroded
surfaces, excessive amounts of salt residues may call for high pressure water jetting, wet
abrasive blasting or, alternatively, dry abrasive blasting, high pressure fresh water hosting, drying, and
finally dry abrasive blasting again.

APPLICATION CONDITIONS:
Apply only on a dry and clean surface with a temperature above the dew point to avoid condensation.
Use only where application and curing can proceed at temperatures above: - 5°/23°F, preferably above
0°C/32°F. The temperature of paint itself should be 15°C/59°F or above. In confined spaces provide
adequate ventilation during application and drying.
PRECEDING COAT:None, or as per specification.
SUBSEQUENT COAT:None, or as per specification.

REMARKS:
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.

Application(s):
Application onto zinc silicate or spray-metallized surfaces (thinning): It is recommended to apply the
paint by using a "mist-coat" procedure provided the paint temperature is approximately above:
20°C/68°F. A thin, undiluted coat is applied (the mist coat) and after a few minutes, a second coat is
applied in the full specified film thickness If the paint temperature is below: 20°C/68°F, thinning (max
15%) may be required.

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:
100-200 micron/4-8 mils. May be specified in lower film thickness for which purpose additional thinning
is required, please see separate APPLICATION INSTRUCTIONS. Avoid application of excessive
film thicknesses.

Shades:
The product is also available in a Micaceous Iron Oxide (MIO) pigmented shade (Shade no. 12430 –
reddish grey).
This product is available in several aluminium pigmented shades with different volume solids content.

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 intervals:
A specification supersedes any guideline overcoat intervals indicated in the table.
