Coppercoat going more green

Coppercoat Strengthens Environmental Credentials With New Bio-Based Resin Innovation – Coppercoat Antifoul

I'm getting my boat copper coated in May. The guys are buying the materials now as we agreed I don't want to be a guinea pig if the latest H&S friendly versions of things like Nitromors are anything to go by.

The new Coppercoat uses a plant based epoxy instead of a petroleum base. There seems to be nothing to dislike except I wonder if other resin users are making the same change? One of the benefits of Coppercoat is the epoxy coating underwater. Worth checking that it is as effective as a barrier and as durable as plastic epoxy. I assume the copper part is not affected.

There have been expensive day sailers made with plant-oil-sourced epoxies for a while now. I've decided not to underestimate modern chemistry's ability to make similar stuff from different sources of the same atoms if enough money, effort and energy is thrown at it.

I would agree that it would be “worth checking” but i’m unclear how this is to be done.

If you mean buy some and test it on a small scale, that would make sense, if practical, though it will likely involve a delay.

If its been in use long enough, there’ll be “the word on the street”

Otherwise, unless one of the mags has done independent testing, there seems unlikely to be any information available

Not sure the epoxy barrier properties are that relevant as the guidance is to roll it on over two coats of normal epoxy paint anyway.

Magazine ... independent ...

I think mags are funded by advertisers rather than subscribers. Not sure I'd trust their review.

My next door but one boat neighbour had all the old anti foul removed and copper coat applied professionally indoors, to describe its performance as poor would be praising it to the hilt while others here report good results.

With such varied results with the same product heaven knows how you could differentiate between new and old.

I would ask Coppercoat - they will have measured and compared.

There have been bio epoxies working exactly as well as petroleum based ones for several years now. You can also use hemp instead of GRP as a cloth with similar strength and properties to E glass. Like most green innovations cost and availability take time to align with the older technologies but tests seem very favourable over the long term so there really should be nothing to worry about
