Epoxy Phenolic paint system under thermal insulation
Epoxy Phenolic paint system under thermal insulation
(OP)
Dear all,
I am looking for information about paint system applied under thermal insulation for subsea structures (FLET, ILT...)
With previous investigations 2 paint systems seems to match regarding the technical constraints
- 2 coats Sigmatherm 230 DFT 150µm for each coat
- 2 coats Thermaline 400 DFT 150µm for each coat
But I can’t find any track records for these paint system in previous project and I need to justify they are field proven paint systems.
Did you use these paints systems in previous project or did you meet these products for subsea structures?
I am not stick with PPG or Carboline, main constraints are :
- 2 coats 150 microns each
- phenolic epoxy
- Under thermal insulation with Temp up to 120°C
- Subsea structures
If you have any paint systems field proven which match these points....
Regards
Marc

Alternately, if you have a decent sales rep - tell them what you need, and they will go through the tech department/lab and get you case studies.

@SJones I know for Phenguard but the main thing is that phenguard system is a 3 coats 930/935/940 100microns each. I also know for the 2 coats phenguard but this paint system is not qualified by Sigma and they don't guarantee this use and I am looking for total DFT of 300microns.
Never heard about phenguard 945, can't find any information about this product.

You are right sigmatherm and Thermaline are used for topside under insulation. Made mistakes when investigating thses paint systems.
ofc if no 2 coats paint systems could fit whith my constraints I will go for a 3 coats system like phenguard 930/935/940. But our scope of work is very important and if we could save time and money with 2 coats instead of 3, we will go for a 2 coats paint system.
After new investigation for SUBSEA this time and not topside , I found plasite 7159 from carboline which perfectly match with my constraints. What do you think about this paint product.
I also try to investigate Belzona 1522 but I can't really find enough information about this product.

And is the pride is justified that is my question ;)
RE: Epoxy Phenolic paint system under thermal insulation
Generally these companies are unwilling to share the results with competitors.
RE: Epoxy Phenolic paint system under thermal insulation
About Belzona 1522 something incredible is that i can't find any PDS for this product. Can't find information about NDFT... Only a poor flyer.
I am investigating Plasite 7159 and Belzona 1522. i need to contact Carboline and Belzona to know if these products are qualified according to NORSOK M-501 and if they have any track records.
cheers

I phone Belzona, first they were not aware of the existence of Belzona 1522, finally the answered me that this product was not fabricated anymore since 15years...
Plasite 7159 is not phenolic epoxy and is not used under thermal insulation.
I think the only paint systems which suit is 3 coats Phenguard. I am not very happy to have only one paint manufacturer available.

I know for the 2 coat phenguard accepted by some companies, unfortunetly this time it's a company which doesn't accept this paint system.
PPG only pre-qualified, according to system 7 of Norsok, the 3 coats system and not the 2 coats. Even if the 2 coats paint system has already been used by major companies we know that this time it won't be accepted.
Hempel answer with a 2 coats system : 2x250µm Hempadur 35900 which is pre-qualified for system 7c NORSOK M-501 (Rev 6).
RE: Epoxy Phenolic paint system under thermal insulation
Regarding my previous investigation, I will go for Phenguard from PPG.
One question regarding Contratherm C25 (Advanced Insulation Plc) and Novolastic (FMC).
I heard about that these companies specified different number of coats(phenguard) under their insulation system.
AIPLC asks for 3 coats of phenguard 100µm each under C25,
whereas FMC aks for 2 coats of phenguard 175µm each.
Do you confirm these assumption or can we apply 2 coats or 3 coats, no matter which insulation system is applied ?
I know that for PPG only the 3 coats system is pre-qualified and accepted as an anti-corrosion system, does FMC or AIPLC will endorsed the guarantee if the specifically ask for 2 coats ?
best regards

But regarding the guarantee, If FMC has qualified the sytem 2coats + Novolastic but PPG as qualified the 3 coats phenguard, FMC will take the responsabilities of possible failure or should I stay in line with PPG requirements to be covered ?
T
he truth is that these subjects are for Total, They won't accept any deviation from paint manufacturer requirements unless the guarantee is fully endorsed by someonelse...Exxon, Chevron and many other major Companies accepted 2 coats but unfortunatly Total can somtimes be narrow-minded
