CSC Services Guide to Polyurea in Power Stations
- 2. Introducing Polyurea – VIP Germany High performance surface protection system
- 3. • Waste water treatment plants • Oil and gas / Petrochemical • Military and defence • Mining • Infrastructure • Food manufacturing Fields of application
- 4. 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
- 5. • CW Cooling systems including: • Drum screens • water boxes • puddle pipes • culverts • Steel storage tanks • Concrete bunds • Internal and external pipe-work Power industry structures
- 6. 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
- 7. 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
- 8. 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
- 9. • Pure Polyurethane • High Polyurethane • Hybrid Polyurea • Pure Polyurea • 100% Pure Polyurea Pure Polyurea? Quickcoat lining for fish farm holding tanks
- 10. • 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
- 11. • 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
- 12. • 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
- 13. • Deteriorations • Drying shrinkage cracks • Crazing • Cold joints • Honeycombing • Pinholes • Contamination • Dusting • Efflorescence Concrete surface defects
- 14. Old coatings Water jetting/grit blasting Salts Water jetting/grit blasting Micro-organisms Hypochlorite Laitance Water jetting/grit blasting Oil & grease Water jetting/grit blasting Preparing Concrete
- 15. • All industrial steel applications require surface preparation by grit blasting to a minimum of SA2.5 Substrate preparation steel
- 16. Most lining failures relate to: 1. Poor substrate prep 2. Lack of understanding of the relationship between substrate, primer and membrane 3. The primers role is – mechanical bond with substrate , chemical bond with top coat Primers and Priming

Hinweis der Redaktion
- Just some of the areas polyurea is being applied across the world.
- Good example of where VIP Germany product was selected and used.
- Do you know what product you need to use ?
- Applying plural component protective linings is NOT like applying paint
- Moisture in substrates must be controlled Eliminates outgassing, adhesion and curing problems Substrates MUST be clean and MUST have correct profile Holes cannot be filled with chemical lining product Trapped contaminants (moisture laden air, water, release agents concrete curing agents and solvents) will cause outgassing and / or blistering Lining will follow existing substrate profile
