Hello, A question which asked many times. I Ave a Tilley FL6 painted black. I have seen many comments on the paint but never seen Hammerstein mentioned. Has anyone used this and if so does it stand the heat well? Thanks for reading this. Sid.
If you mean Hammerite - my FL6 was brush painted with "Smootherite" - its not so hammered finish cousin, a long long time ago. I am not totally happy with the finish but it did stop the rust for over 25 years. It does need time to cure properly and some would put things in ovens but that is not so practical with a FL6. So if you used it I would leave it for a fortnight before putting paraffin near it. The only bit that gets very hot is the chimney, some here have painted this with high temperature paint, but mine is the same paint everwhere.
Don't know about others but I am finding modern day hammerite products not a shade on their older ones, I suspect that so many ingredients are banned nowadays and stuff is so eco friendly it doesn't have the power. I find the same story with wood preservatives.
I think the original Hammerite company, based not too many miles away from here, were taken over by one of the big boys quite a while back. That might explain the change of product - they probably just wanted the Hammerite name to use on one of their inferior products...
I would have thought more to do with certain chemicals and reduction in VOCs (European Decopaint Directive 2004/42/EC) - hammerite thinners used to be trichlorethane but that is a CFC so outlawed now.
VHT Flame Proof Very High Temperature Paint VHT Flat Black Flame Proof Very High Temperature Paint (312g) May be worth a try, primer, flat black, (colours are limited) and a satin clear coat. Also JB Weld Extreme High Heat Temperature Resistant Metallic Paste as a filler on pitted steel.
@Sidney Harbour Note: If you buy a paint that needs curing by baking at high temperatures you can’t use it on components that are soldered. For soldered parts I stop at paint that cures at 94°C or thereabouts. Cheers Tony
Hi Tony, Never thought of that one. Locked away in my memory now. Great tip many thanks for your advice. Keep safe, Sid.
Hammerite is now a subsidiary of Akzo Nobel, who has also acquired Imperial Chemical Industries(ICI) quite awhile back. I'd say most of the Big Boys in the coatings industry would need to comply to the current environmental laws and regulations. There'd certainly be a fair amount of change in the compositions of the products in order to get the necessary approvals for production and market. Not only the solvents used had to be changed but the binders need to be compatible in order that these are useable. Some of the fillers such as zinc chromate and lead compounds had to be totally omitted. Some of the more toxic pigments (cadmium sulfide, mercury compounds, etc) had to be done away with. All in all, the change can be quite substantial. I'd not be too surprised if the properties might not be as expected from the original, older products. It applies to all reputed brands/companies.
I know a bit of it. There is an Akzo Nobel paint factory right in front of the Plant where I'm working. It used to be the ICI Paint factory:-
