Dyneema UV Protection

Has anyone got any idea what I can coat unsheathed Dyneema in to stop or reduce UV degradation ?

Re: Dyneema UV Protection

Multihullnets.com sells Dyneema netting, coloured black. I don't know what they use to colour it, but perhaps they'd tell you. They might sell you something, or put you in touch with their suppliers.

Good luck.
Cheers.
Paul.

Dyneema really doesn't need sun protection. People use raw uncovered Dyneema as standing rigging.

Dyneema degrades under UV light. You can buy and use Ďtreatedí Dyneema that is more resistant to the degradation. The treatment is a solution and itís that solution that I am looking for. I have been told itís water based Urathane but I cannot find it online.

I wonder about products like Rope Dip (water based urethane--Defender sells it) from Flexdel. I know from personal testing that it is VERY effective (10x) at protecting nylon and polyester from chafe. But I have no idea about Dyneema or UV. Additionally, it stiffens the rope.


I guess I need to do some testing....

Marlow D12 max has a UV and chafe resistant coating. Very tough stuff.
