Product Data

Basic data at 20°C (68°F)

Notes:
See addtional data: Spreading rate and film thickness, Overcoating intervals and Curing time. When applying more than one coat, it is recommended that the total DFT should not exceed 250 µm (10.0 mils). Colour will drift at elevated temperatures.<p>

Recommended Substrate Conditions and Temperatures

• Coating performance is proportional to the degree of surface preparation.
• Steel; pretreated minimum ISO-Sa2 (SSPC SP-6) or higher with blasting profile 25 – 75 µm (1.0 – 3.0 mils).
• For touch up and repair, power tool cleaning in accordance with SSPC SP-11 is acceptable.
• Galvanized steel; sweep blasted to roughen the surface to remove any zinc salts which might be present, SSPC SP-16 with blasting profile 40 – 75 µm (1.5 – 3.0 mils).
• Stainless steel and non-ferrous metal; degreased and sweep blast, SSPC SP-16 with blasting profile 40 – 100 µm (1.5 – 4.0 mils).
• Concrete / Masonry; see specific primer.
• Compatible previous coat must be dry and free from any contamination.
• When applied to zinc silicate primer, a mist coat and full coat technique is required. 15% thinning is recommended for mist coat.
• Aged suitable coating must be dry and free from any contamination, it may require abrading prior to applying this product.
• Prepare damaged areas to original surface preparation specifications, feathering edges of intact coating.
• Substrate temperature during application and curing should be above 0°C (32°F).
• Substrate temperature during application and curing should be at least 3°C (5°F) above dew point.
• Relative humidity during application and curing should be above 40% to obtain optimal curing properties.

Note: FD hardener should be used when ambient temperature is below 5°C (40°F).

System Specification

Primers: Direct to substrate, DIMETCOTE Series, AMERCOAT 68 Series, AMERLOCK 400 / 2 Series, SIGMAZINC Series, AMERCOAT Epoxies and SIGMA Epoxies.

Instructions for Use

Mixing ratio by volume: base to hardener 80:20 (4:1). Use a power mixer powered by an air or explosion-proof electric motor. No induction time required. Pot life is 4 hours at 20°C (68°F); Note: See ADDITIONAL DATA – Pot life.

Air spray

Recommended thinner: THINNER 60-12 (AMERCOAT 911) or THINNER 21-06 (AMERCOAT 65) for global, THINNER 21-25 (AMERCOAT 101) is recommended for above 90°F (32°C) in US only
Volume of thinner: 5 - 10%, depending on required thickness and application conditions
Nozzle orifice: 1.5 – 2.0 mm (approx. 0.060 – 0.079 in)
Nozzle pressure: 0.3 - 0.4 MPa (approx. 3 - 4 bar; 44 - 58 p.s.i.)

Airless spray

Recommended thinner: THINNER 60-12 (AMERCOAT 911) or THINNER 21-06 (AMERCOAT 65) for global, THINNER 21-25 (AMERCOAT 101) is recommended for above 90°F (32°C) in US only
Volume of thinner: 0 - 5%, depending on required thickness and application conditions
Nozzle orifice: Approx. 0.38 – 0.48 mm (0.015 – 0.019 in)
Nozzle pressure: 20.0 MPa (approx. 200 bar; 2901 p.s.i.)

Brush/roller

The recommended DFT cannot be reached in one coat. Use a high quality natural bristle brush and/or solvent resistant, short nap roller. Ensure brush / roller is well loaded to void air entrainment. Be sure to maintain a wet edge.

Cleaning solvent

THINNER 90-53, THINNER 90-58 (AMERCOAT 12) or THINNER 60-12 (AMERCOAT 911)

Notes:
Surface should be dry and free from any contamination. When re-coat between dry through time and 7 days, solvent wipe surface with any of PSX 700 thinners prior to application of the second coat of PSX 700. Hardener manufactured in Europe is fast drying version only with "PSX 700 FDE Hardener" name.

Curing time with standard hardener for DFT up to 175 µm (7.0 mils) at RH 40% or above

Safety Precautions

This is a solvent-borne paint and care should be taken to avoid inhalation of spray mist or vapor, as well as contact between the wet paint and exposed skin or eyes. For paint and recommended thinners, see information sheets 1430, 1431 and relevant Material Safety Data Sheets.
