EPOFIX is a two-pack epoxy primer intended for use on iron, aluminum, galvanized iron and light alloys, as well as concrete surfaces. It requires thorough surface preparation through sanding or mechanical cleaning followed by degreasing. The primer consists of Components A and B, which are mixed together prior to application by spray gun, airless sprayer, or by brush/roller for small areas. EPOFIX dries to touch in 4-5 hours at 20°C and achieves full hardness within 24-36 hours. It offers resistance to acids, alkalis and solvents and can be overcoated within 8 hours for optimal adhesion when mixed with Component B.

Name: EPOFIX Category: primer
Definition: Epoxy primer V.O.C. limit: 540 g/l
Code: 29.3 V.O.C. ready to use: 480 g/l
Product according to 2004/42/CE
NATURE OF THE PRODUCT
Two pack epoxy enamel to be mixed before use.
GENERAL USES
High solid universal primer: can be overcoated with most of top coats. It can be applied on iron, aluminium,
1
galvanised iron and light alloys surfaces, concrete.
APPLICATION METHOD
PREPARATION OF SURFACES
This means that presence of grease and oils on the surfaces, is absolutely not allowed.
The cleaning of the application surface should be total and painstaking and it is a fundamental and
necessary condition to obtain positive result of the painting cycle.
- Ferrous surfaces: SA2 sanding or very careful mechanical cleaning followed by degreasing with
thinners.
- Galvanised iron: soft sanding followed by degreasing with thinners.
- Aluminium: sanding, followed by degreasing with thinners. Otherwise, chromate or phosphorous
chromate treatment.
- Concrete: the concrete casting should be aged for 4 weeks and it has not to present bleeding. In this
case the incoherent film of dust due to the bleeding, should be removed by sanding or shot blasting.
PREPARATION OF THE PRODUCT
Code name By weight By volume
Component A 29.3 Epofix 100 100
Component B 02.120 Eporex standard 20 33
type

Component B 02.150 Eporex quickly type 20 33
Carefully mix until an even colour and consistency are obtained. For airless applications no dilution is
requested or maximum 10% dilution, for standard airmix application dilute with 07.006 in a percent of 15-
20% to obtain a viscosity of 24"-30” Ford 4 .
APPLICATION
Spray gun: nozzles of 1,4-1,6 mm. diameter and 3-5 atm. pressure.
Airless. nozzle 0,09 inches, 120-150 bar
Electrostatic ok
Brush/roller Only for small surfaces
