Hempel Hempadur 45143 is a two-component, polyamide adduct cured epoxy paint with good wetting properties and low water permeability.
Hempadur 45143 is self priming and forms a hard and tough coating with good resistance against abrasion and impact as well as to seawater, mineral oils, aliphatic hydrocarbons and splashes from petrol and related products.
Hempadur 45143 is suitable as a high build primer, intermediate and/or finishing coat in (heavy duty) paint systems according to specification. Hempadur 45143 is also suitable for repair and maintenance work at application temperatures above -10°C/15°F on hatch covers, decks, in cargo holds, etc. Another use is as a ballast tank coating. Hempadur 45143 is intended for use in cold/temperate climates, Hempadur 45141 for warmer climates - see Application Guide via data sheets tab. Harmless to grain cargoes.
In order to obtain best performance, abrasive blast cleaning is recommended. However, HEMPADUR 45141/45143 may be applied on rusty steel surfaces where higher performance is needed than obtainable with conventional coatings but where mechanical cleaning and dust removal can only be carried out (beside the removal of salts and of oily contaminants). Remove oil and grease with suitable detergent, salt and other contaminants by (high pressure) fresh water cleaning. Spot repair as necessary.
For Full Coating
Compatibility with old system: HEMPADUR 45141/45143 may exceptionally be applied directly on top of an old alkyd paint system provided this is tightly adhering. It is furthermore preferable that the old system is less than approximately 500 micron in film thickness. A test patch should always be performed before full coating is decided. Even old chlorinated rubber and vinyl systems may be overcoated but with an inherent risk of later tendency to "liftings" along mechanical damage and similar weaknesses.
Removal of old system: Full coating after mechanical removal of an old paint system is possible too. Yet, it must be considered that mechanical cleaning may produce a very smooth surface giving reason to reduced adhesive forces.
