INFRALIT EP/PE 8087-18

Epoxy/polyester powder

  • Powder coating

INFRALIT EP/PE 8087-18 is a powder coating based on a mixture of solid epoxy and polyester binders. At elevated temperature the powder will melt, cure and form the final paint film.

Suitable for coating metal industry products, such as lighting fixtures, apparatuses, wire gratings and refrigerating fixtures. The mechanical and chemical resistance as well as the anticorrosive properties of INFRALIT EP/PE 8087-18 Epoxy/Polyester powder are almost equal to those of epoxies. On outdoor exposure INFRALIT EP/PE 8087-18 epoxy/polyester powder has a tendency towards matting down (chalking) similar to that of pure epoxies. On the other hand, its tendency to yellow on overbaking and exposure to heat and ultraviolet light is minor as compared with epoxy powders. Among special properties of INFRALIT EP/PE 8087-18 are improved levelling and wide gloss range.

Surface preparation

STEEL SURFACES: Remove grease and dirt. After that blast-cleaning at least to preparation grade Sa 2½ (ISO 8501-1) and/or a suitable chemical pretreatment. ALUMINIUM SURFACES: Remove grease and dirt. After that chromating or alternatively a suitable chemical pretreatment. HOT-DIP-GALVANIZED AND ZINC-ELECTROPLATED SURFACES: Remove grease, dirt and white rust by e.g. alkali wash. Depending on exposure conditions, chromating or alternatively a suitable chemical pretreatment is also required.

Storage

The storage life is minimum 18 months in dry and cool conditions when the temperature during storage and transportation is max. +25°C. Take special care during high temperature seasons. Avoid storing close to heat sources and heaters in trucks and storages. Don’t store in direct sunlight. The recommended expiry date of the powder coating that has been stored according to the instructions is shown on the package label.
Practical spreading rate 6 - 12 m²/kg depending on the film thickness.
Spraying TRIBO/CORONA
Curing time 15 min/180°C (metal temperature)
Colours By agreement.
Packages 20 kg.
Safety markings See safety data sheet. The powder itself is non-flammable, but with air it can form an explosive mixture that in presence of adequate ignition energy ignites. The lower explosion limit of typical powder coatings is between 20 g/m³ and 80 g/m³ (CEPE, Safe Powder Coating Guideline 8th Edition, 2020). Ventilation of the spray booth should be adjusted so that the concentration of powder in the air is less than 50% of the lower explosive limit value. On calculation of the powder concentration in the spray booth, the powder deposited on the workpiece is not taken into account.
Gloss value 20-30
