Fontecoat EP 50 Beige - Water-borne epoxy primer

Fontecoat EP50 Beige
DESCRIPTION A two-component water-borne epoxy primer.

Used as a primer or an intermediate coat in epoxy / polyurethane systems. Can also be used as a topcoat or as a single coat paint in epoxy paint systems for steel surfaces.


Recommended uses Recommended for framework, service platforms, conveyors and other steelwork, machinery and equipment.

Features Very good resistance against mechanical and chemical stress. Resistant to diesel and biodiesel (RME) fuel.
Colour Range Beige.
Gloss groups Semi-gloss

Application conditions All surfaces must be dry. The temperature of the ambient air, surface or paint should not fall below +15ºC during application and drying. If the ambient relative humidity is 70% or higher, appropriate measures must be taken to reduce the relative humidity in the drying stage (forced drying or dehumidifier). The surface temperature of the steel should remain at least 3ºC above the dew point.
Preparation Oil, grease, salts and dirt are removed by appropriate means. (ISO 12944-4)

Steel surfaces: Blast clean to grade Sa2½. (ISO 8501-1) If blast cleaning is not possible, phosphating is recommended for cold rolled steel to improve adhesion.

Primed surfaces: Oil, grease, salt and dirt are removed from the surface by appropriate means. Repair any damage to the primer coat. Note the overcoating time of primer. (ISO 12944-4)
Priming Fontecryl AP, Fontecryl PP, Fontezinc 85, Fontecoat EP 50, Temazinc 77, Temazinc 88, Temazinc 99, Temakeep and Temacoat GPL-S Primer.
Finishing Fontecoat EP 50, Fontedur HB 80, Temasolid SC 60, Temadur 50 and Temacryl EA 50.
Painting By airless spray or brush. If necessary, the paint can be thinned 0 - 10%. Airless spray nozzle tip 0.013" - 0.023" and nozzle pressure 140 - 200 bar. Spray angle shall be chosen according to the shape of the object. For large flat surfaces, and for nozzle tip above 0,015'', 40° or higher spray angle is recommended. Forced drying must be used when nominal dry film thickness (NDFT) is above 140 μm. Forced drying can be used up to 450 μm wet film thickness. 200 μm dry film thickness should not be exceeded.

For aluminium and zinc substrates and when applied on zinc rich primer it is recommendable to apply a mist coat: first a thin layer, then let the water evaporate for 5 - 10 minutes and then apply the full coat.
Mixing of components First stir base and hardener separately. The correct proportions of base and hardener must be mixed thoroughly before use. Use mechanical mixer for mixing.
Cleaning of tools Clean the spraying equipment immediately after use. First run the equipment with water to remove excess paint from the equipment. Then use 10- 15% and 40-60% mixtures of Thinner 1109 with water to remove the rest of the paint from the equipment. Finally wash with undiluted Thinner 1109.
Wash the equipment with water before resuming painting. Failure to do so can cause serious surface defects.
