Water Borne Inorganic Zinc Rich Silicate Primer

PRODUCT SPECIFICATIONS:

Product description
HJ-555 is a two-pack, self-curing, water borne inorganic zinc rich silicate primer which can be applied in high film
thickness.
Recommended use
A general purpose, heavy duty, anti-corrosive primer:
1. As the first coat in a multiple layer system with water borne coatings, as well as with suitable solvent borne
coatings, such as epoxy and others - not to be overcoated with alkyds.
2. As a single coating for long term protection of the interior of steel tanks. A separate resistance list is available.
3. As a single coat system for atmospheric service including marine locations.

The given data must be considered as guidelines only. The actual drying time/times before recoating may be shorter or
longer, depending on film thickness, ventilation, humidity, underlying paint system, requirement for early handling and
mechanical strength etc. A complete system can be described on a system sheet, where all parameters and special
conditions could be included.
Typical paint system
HJ-555 1 x 75 μm (Dry Film Thickness)
WaterFine Special 2 x 60 μm (Dry Film Thickness)
WaterFine Topcoat 1 x 50 μm (Dry Film Thickness)
FOR INTIOR OF TANKS OR SINGLE COAT SYSTEM:
HJ-555 1 x 125 μm (Dry Film Thickness)
Other systems may be specified, depending on area of use
Complete curing:
Curing of HJ-555 to be evaluated by coin test and water-insolubility test.
When the HJ-555 is used as a one coat system for the interior of tanks the paint must be completely cured before
the tank is put into service. In order to achieve this the following procedures can be used:
· Apply 125 μm HJ-555.
· Let the paint dry/cure with good ventilation and low humidity until minimum recoating time is reached.
· Spray water (seawater is preferred) on the coating and leave the tank closed. Repeat the water spraying 3 - 4
times during a 48 hours period.
· Remove the water and let the tank dry.
Procedure for preparation and cleaning of application equipment:
To avoid solvent contamination of the water borne paint the spraying equipment has to be conditioned before use. All
equipment containing solvents in the pump, hoses and gun have to be thoroughly cleaned according to the following
instructions.
If the application equipment is made in stainless steel, designed for and only used for application of water borne
coatings this preparation and cleaning procedure is not needed.
Before spraying:
Circulate Honest joy Thinner No. 17 through the equipment and hoses. Then Honest joy Thinner No. 4 before fresh clean water.
After spraying:
Clean the equipment and hoses with water and detergent, then circulate Honest joy Thinner No. 4 and finally Honest joy Thinner
No. 17.
Storage
The product must be stored below 25°C and in accordance with national regulations. Storage conditions are to keep
the containers in a dry, cool, well ventilated space and away from source of heat and ignition. Containers must be kept
tightly closed and kept from freezing. Storage at elevated temperature will significantly reduce the product shelf life.
SHELF LIFE: Component A, 2 years; component B, 1 year.
Handling
Handle with care. Stir well before use. Continuous stirring during application will prevent the heavy zinc pigment from
settling.
Packing size
7,3 kg Comp. A , 26 kg Comp. B (Together 10 l paint)
