Polyaspartic Technology - How It Benefits The Industry

Industrial and civil construction projects are becoming more demanding in terms of quality, durability, sustainability and aesthetics of products. This, for most structural steel fabrication shops and manufacturing plants, means that cost pressure is rising - while product delivery cycles are becoming faster and faster. Therefore productivity and efficiency - as factors of time and cost – play a paramount role in securing contracts and delivering product packages in time.

For more than 15 years Sherwin-Williams have been developing polyaspartic technology and using the unique benefits in a range of applications to help speed up the production process. The adoption rate to this technology platform continues to increase as it benefits contractors in high-performance steel protection systems to fast return to service floor coatings.

Proven Protection

This next-generation technology continues to add value across the supply chain in the following ways:

Productivity improvement

• Dry film thickness up to 225 microns in one layer with no outgassing
• C3 – One-layer “direct-to-metal” application
• C4/C5 - Two-layer application over approved primers

Manufacturing capacity increase

• Elimination of bottle-necks in painting
• Time to handle 2 hours at 20°C, 50% RH
• Application of C3, C4 and C5 coating systems in 8-hour single shift

Application cost reduction

• C3 – up to 50% cost/m 2 decrease against two-layer systems
• C4/C5 – up to 40% cost/m 2 decrease against three-layer systems

Total production cost reduction

• C3 – up to 25% cost/m 2 decrease against two-layer systems
• C4/C5 – up to 15% cost/m 2 decrease against three-layer systems
• Energy cost saving – negates the need for “force curing” at high temperatures

Environmental improvement

• Low carbon emissions – negates the need to run infrared, electric or gas ovens
• Low VOC emissions – VOC at 190 g/l (EPA Method 24) or 193 g/kg (EC SED)

Long-term corrosion protection

• Independently certified to ISO12944:2018 Part 6 C3, C4 and C5 (Regime 2)
• Coating system design life up to 25 years or over
• Excellent gloss and colour retention

Surface Preparation

Surface must be clean, dry, and in sound condition. Remove all oil, dust, grease, dirt, loose rust, and other foreign material to ensure adequate adhesion.

Refer to the Application Guide for detailed surface preparation information.

The systems listed above are representative of the product's use and other systems may be appropriate.

Minimum recommended surface preparation:

Iron & Steel:

• Sa2.5, (BS EN ISO8501-2007)
• 50-75 microns
• (2-3 mil) profile

Galvanizing:

• SSPC-SP16
• 50 micron
• (2 mil) profile

Approved Primers

Envirolastic 2500 is a fast cure technology that is designed to provide rapid return to service, as a result it is not compatible with all primers. The following primers are currently approved for use:

• Macropoxy 400
• Fastclad 7220
• Zinc Clad IV EU

The maximum overcoating interval on the approved list of primers is 28 days at all temperatures. If this is exceeded, it is recommended that the primer surface is abraded and cleaned down primer to overcoating with Envirolastic 2500.

Application Conditions

Temperature:

• 5°C (41°F) minimum
• 49°C (120°F) maximum (air, surface, and material)
• At least 3°C above dew point

Minimum Paint temperature 5°C for application.

Maximum paint temperature 35°C for application.

Maximum Relative Humidity 85%.

Minimum Relative Humidity 35%.

Maximum air and surface temperature 50°C.

Clean application equipment thoroughly before and after use. Mixed coating is sensitive to water, use water traps in all air lines.

Moisture contact can reduce pot life and affect gloss and colour.

Thoroughly mix both components before using or dry time, gloss and colour will be affected.

• Relative humidity: 85% maximum

Refer to the Application Guide for detailed application information.
