Protective Coatings 2
The Challenge
Protective Coatings 3
In the -196°C to 230°C (-320°F to 446°F) temperature range, two specialist products currently dominate conventional specifications, but present challenges for large complex projects.
The Challenge
Epoxy Novolac Modified Silicone Aluminium Silicone Epoxy Mid-Coat Epoxy Tie-Coat Epoxy Phenolic Zinc Silicate
The Challenge
insulation due to the reverse polarity phenomenon that accelerates carbon steel corrosion < 175ºC
Protective Coatings 5
NACE SP0198
6 Protective Coatings
The Challenge
– Poor crack resistance if the dry film thickness is too high – Slow drying below 10ºC (50ºF) Lead to poor CUI resistance if not properly controlled

The Benefits
Tolerance to over application
Test consists of heating to 200ºC for 8hrs and leaving to cool to ambient for 16hrs; test is repeated 5 times Standard Epoxy Phenolic 2 x 175µm stoved at 200ºC Standard Epoxy Phenolic 2 x 225µm stoved at 200ºC Alkylated amine 2 x 350µm stoved at 200ºC
The Benefits
Fast and low temperature curing = Productivity Increase

Information >4,000L of Alkylated Amine was delivered for this project. Applied by Cameron in Italy, the product will be used on valves running at high temperature on the Yamal LNG Project in Russia. Project YAMAL LNG Project Benefit Site touch up down to – 5°C. Epoxy phenolic coatings would have required expensive heating arrangements.
