PRIMAPOX – GYM is a high quality two components polyamide cured anticorrosive epoxy primer,
designed for structural steel and piping to be exposed to highly corrosive environments, C5I or C5M
(ISO 12944-2). Recommended for offshore environments, refineries, power plants, bridges, pipeline
for fuel, crude oil or natural gas and for mining equipment. It can also be used as finish coat for
structural steel of food and chemical processing plants.

Suitable Surfaces

 Steel and non ferrous metals properly prepared and blast cleaned to ISO-Sa2½
 Concrete free of contamination, dust and efflorescence, and properly prepared

Bare Steel:

Cleanliness: Blast – cleaning to Sa2 1/2 (ISO-8501-1:2007). Power tool cleaning to min. St2 (ISO 8501-
1:2007) may be acceptable, subject to exposure conditions.

Shopprimed Steel:

Clean, dry and undamaged approved shopprimer

Coated Surfaces:

Clean, dry and undamaged compatible primer .

Other Surfaces:

For aluminum substrates, thorough washing and sweeping with a nonmetallic blast medium is required.

Application Conditions

Substrate temperature should be 10°C or above for applicaƟon and during cure and a minimum of  3°C above the dew point. Adequate dry air ventilation is recommended for optimum drying.

Application Information

Thinning should only take place after the two components have been thoroughly mixed.

Brush and Roller

Thin if required with 0-5% Paint Thinner Colorama TH907EP.

Conventional Air Spraying

– Thin with 5-25% Paint Thinner Colorama TH907EP, as required.
– Tip size – 2.0 mm
-Tip pressure – 60 psi (0.4Mpa) approximately
Airless Spraying
– Thin with 0-20% Paint Thinner Colorama TH907EP, as required
– Tip size – 0.58-.79 mm approximately
– Tip pressure – 2100 psi (15Mpa) approximately
Cleaning Thinner
Equipment should be cleaned immediately after use with Paint Thinner Colorama TH907EP.
Drying time:
Drying times are affected by air ventilation, temperature, film thickness and number of coats.

The given data serve as guideline only. The actual drying time differs according to film thickness,
ventilation, humidity and underlying paint system.
Keep the containers in a dry, cool, well ventilated space and away from source of heat and ignition. Containers
must be kept tightly closed.
Handle with care. Stir well before use.
Packing Size:                                                          5 L & 18 L
