Introducing Polyurea – VIP Germany

High performance surface protection system

Page 3: CSC Services Guide to Polyurea in Power Stations

• Waste water treatment plants• Oil and gas / Petrochemical • Military and defence • Mining • Infrastructure • Food manufacturing

Fields of application

Page 4: CSC Services Guide to Polyurea in Power Stations

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

Page 5: CSC Services Guide to Polyurea in Power Stations

• 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

Page 7: CSC Services Guide to Polyurea in Power Stations

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

Page 8: CSC Services Guide to Polyurea in Power Stations

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

• 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

Page 13: CSC Services Guide to Polyurea in Power Stations

• Deteriorations• Drying shrinkage cracks• Crazing• Cold joints • Honeycombing • Pinholes• Contamination • Dusting • Efflorescence

Preparing Concrete

Page 15: CSC Services Guide to Polyurea in Power Stations

• All industrial steel applications require surface preparation by grit blasting to a minimum of SA2.5

Substrate preparation steel

Page 16: CSC Services Guide to Polyurea in Power Stations

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
