BestPrimer EP703 is a special moisture barrier epoxy primer. It is a two
pack low viscosity epoxy.
BestPrimer EP703 has been specially formulated to improve penetrating
and adhesive ability to moist substrate as a moisture barrier for all kind of
BestCoat layer.
-
BestPrimer EP703 is applied in the special case in wet areas, newly poured
concrete (in 24 hours) or places contaminated oil ... that cannot be dried,
prevented moisture or cannot clean oil on basement, walls, swimming
pools, ground floor of factory, warehouse, garage ...
-
Deep penetrating.
-
Well adhesive with highly humid or oil surface.
-
Mild acid, alkali, chemical, mineral oil...resistances.
-
Easy to apply by brush, roller, sprayer...
-
Friendly with environment.

Substrate
requirement:
-
The high absorbing or breakable surface: coat at least 02 layers
-
The average rough, dense and flat surface: only one layer
-
The hardened surface: Use BestCorros for surface treatment before
applying BestPrimer EP703.
Surface
condition:
-
Concrete surface: Compressive strength:
≥
20 MPa, tensile strength:
≥
1.5 MPa.
Surface should be flat, solid, steady, dry , water free, humid areas must be
dried by clean clothes
Impurities, broken pieces, dust should be cleaned as required
Mixing:
-
Before execution, component A and B should be properly mixed under the
right ratio by slowly stirring (at speed of 300
÷
400 rpm).
Minimum mixing time is at least 03 minutes or longer until having the best
mixture as require
Apply material immediately after mixing
Application:
-
Apply by roller, pressure sprayer or brush one full coat of BestPrimer EP703
at a approximate rate 0.15 ÷ 0.25 kg/m2
/ layer (depends on surface status).
The second layer must apply with a direction perpendicular to the first
When application the next layer, make sure the previous layer is completely
dry
- Note: Do not use expired material Site area should be prevented from direct sunlight, rain during curing period.
Cleaning:
-
Use BestThinner SC01 to clean equipments immediately after the execution
and before the mixture’s hardening
Safety:
-
Both components may cause allergic to skin. Avoid prolonged skin contact.
Protective clothing is highly recommended.
In case of contact with eyes, rinse immediately with plenty of clean water and
seek medical advice.
