Transcript of CSC Services Guide to Polyurea in Power Stations
Introducing Polyurea – VIP Germany
High performance surface protection system
• Waste water treatment plants• Oil and gas / Petrochemical • Military and defence • Mining • Infrastructure • Food manufacturing
Fields of application
Bunded Areas Under Tanks, Finland• Ashland Chemicals• Sealed and coated existing
bunded areas to prevent chemical spillage
• Application completed in very short time, not disrupting loading of tanks and manufacturing process
• CW Cooling systems including: • Drum screens• water boxes• puddle pipes• culverts
• Steel storage tanks• Concrete bunds• Internal and external pipe-work
Power industry structures
1. Fast return to service• Fast reactivity and cure times from 5 seconds up • Can build to any thickness in one application• Tack free• Can be applied in sub-zero temperatures• Insensitive to moisture and humidity during
application • Use of catalysts not required
2. Long life cycle• Once cured leaves a flexible, durable
tough surface• High impact and abrasion resistance• Resistant to most aggressive chemicals,
solvents, acids and caustics• UV, chlorine and saltwater resistant
3. Formulated for different physical properties
• Seamless application – no joints or weak spots
• High elongation • High tensile strength• Hard or soft compound• Varying levels of
chemical resistance Chemical Bund Lining
• Pure Polyurethane • High Polyurethane• Hybrid Polyurea• Pure Polyurea • 100% Pure Polyurea
Pure Polyurea?
Quickcoat lining for fish farm holding tanks
• Knowledge to correctly assess project• Substrate preparation options and knowledge • Priming options and procedures• Correct product selection• Technical knowledge of equipment• Quality control knowledge
Application success
• High performance lining for when performance is critical
• 100% UV stable• Elongation 400%• Tensile strength 32 mpa – 4650 psi• Hardness 45 Shore D
QuickSpray Supreme HP
• Moisture in substrates must be controlled • Substrates MUST be clean and MUST have correct
profile• Holes cannot be filled with chemical lining product • Trapped contaminants will cause outgassing and /
or blistering• Lining will follow existing substrate profile
Substrate preparation
• Deteriorations• Drying shrinkage cracks• Crazing• Cold joints • Honeycombing • Pinholes• Contamination • Dusting • Efflorescence

Preparing Concrete
• All industrial steel applications require surface preparation by grit blasting to a minimum of SA2.5
Substrate preparation steel
Most lining failures relate to:1. Poor substrate prep2. Lack of understanding of the relationship
between substrate, primer and membrane3. The primers role is – mechanical bond with substrate , chemical bond with top coat
