• Tough, hard wearing flexible film, with excellent color retention and weathering resistance.
• Good chemical resistance and excellent water resistance.
• Can be easily over coated after long exposure periods.
• Cures at low temperatures.
• Used as a finish coat for various surfaces such as wood, concrete floors and structural steel of food and chemicals processing plants and anti-chemicals flooring.

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.
• Wood must be abraded with sand paper No. 320 and primed with PU or polyester wood sealer.

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 application 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 TH908UE.

Conventional Air Spraying:

• Thin with 5-25% Paint Thinner Colorama TH908UE, as required.
• Tip size – 2.0 mm.
• Tip pressure – 60 psi (0.4Mpa) approximately.

Airless Spraying:

• Thin with 0-20% Paint Thinner Colorama TH908UE, 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 TH908UE.

Drying time:

Drying times are affected by air ventilation, temperature, film thickness and number of coats.
