841 Aluminum Powder Epoxy Asphalt Prime Coat
(Double Components)
|
I. Features: 841 Aluminum Powder Epoxy Asphalt
Prime Coat is cured from polyamide, the film is wearable resistant
with high adhesive and such performance as sea water resistant, crude
oil and fuel resistant, but it is not arene solvent resistant (including
gasoline or powerful solvent), the color will fade if it contact with
chain hydrocarbon solvent.
II. Purpose: This product can be used as the prime coat for bilge
with long effect as the protective coating for steel structure under
serious corrosion environment.
III. Physical Parameters: 1. Coating Surface: Dull Gloss
2. Color: Silver Brown
3. Solid Content: 70%
4. Theoretic Coating Area: 7.5m2/kg
5. Flash Point: 28c¡ã
6. Dry to Touch: 3-4 hours
7. Completely Curing: 7 days
8. Shelf Life: 1 year (stir before construction)
IV. Construction Description: 1. Mixing Proportion: Component A: Component
B = 1.2 : 1 (Weight Proportion)
2. Construction Method: spraying, brushing, rolling
3. Thinner: x-7
4. Max Thinner Consumption: 5%
5. Mixing Use Time: 4 hours
6. Tools Cleaning: x-7
7. Paint Film Thickness: Wet Film 175 micron, Dry Film 120 micron
8. Time for Re-Coating: please see Remarks
9. Surface Treatment: new steel surface - suggested sand blast: Sa2.5
Class, if it requires to temporarily protect the steel surface, prime
coat is applicable, before brushing this product, please thoroughly
remove the dirt after sand blasting.
10. Maintenance: Remove oil and grease with suitable detergent, flush
oil and other dirt with pressure water, clean the damaged area with
sand blasting or power tools, thoroughly clean the whole surface from
edge and corner and coat to regulated thickness.
V. Construction Conditions: This product can only be constructed when
environment temperature exceeds 5C¡ã (construction and curing can be
normally fulfilled), when constructing, the temperature of paint shall
exceed 15C¡ã, and the temperature of construction surface and paint
shall range 15C¡ã-25C¡ã, in order to prevent water condensation, please
construct when the temperature is higher than dew point under dry
weather. Powerful ventilation is required if it is constructed in
narrow space and when drying the film.
VI. Matching Paint: Chlorinated Rubber Paint, 741 Aluminum Powder
Chlorinated Rubber Paint.

VIII. Paint Film Thickness: The thickness is confirmed according to
the using purpose and area, but it will also change the coating area,
drying time and re-coating time, the normal range of dry film shall
range 125-200 micron.

The max time for re-coating the product can be doubled, but it shall
not have water or other dirt on the surface before coating, no leakage
is allowed for the surface of the first layer of coating, assure adequate
curing conditions, keep favorable ventilation and temperature and
film thickness, dilute according to the above proportion to prevent
leakage, prevent over temperature, if it exceeds the max time for
re-coating, please grind the surface of prime coat before coating,
thus assuring favorable adhesion between coating films, otherwise
the color may possibly penetrate into other coating, which may influence
the appearance instead of performance of paint.
X. Cautions: This product is only applicable for professional purpose.
XI . Safety: The product is only applicable for professional purpose.
Please strictly follow relative safety laws and regulations when transporting
and storing the product. Prevent inhaling solvent or paint fog when
constructing, skin and eyes shall not contact this product. Provide
powerful ventilation if it is constructed in narrow space or poor
ventilated space. It requires to wear protection mask and take effective
measures for preventing fire and explosion even though it has favorable
ventilation. |
