Tinting Epoxy

[mbmcdermott18]

Gentlemen, I am working on another sea chest and had to repair a few blemishes on the inside of the chest. I have faired the blemishes and now need to re coat the inside. I was thinking of using west system pigment or gel coat pigment to tint my US composites 3:1 epoxy white and then paint the inside of the chest. I can't use paint bc of the moist nature of the interior of the chest. Has anyone done this? Does the epoxy need to be thinned/reduced with anything?

Thanks in advance for any help you can give me.

I use the white all the time and have used black when doing carbon fiber repairs for cosmetic purpose.

Look at the product Tile Clad(SW/Paint)...they paint the inside of water towers with this stuff.

We do it all the time. The inside surfaces of all my hatches (seacraft), the ice box, anchor locker, bilge, etc, are all coated with pigmented epoxy. It moisture and fuel "proof".

I use about 10% by volume pigment to epoxy, some pigments are more opaque than others. You should be able to get full coverage with two thin coats.

here is a picture of the bilge area before bonding down the sole

Thanks for the replies guys. I am going to pick up some tint today and give it a shot. Would like to use tile clad but do not want to wait to order some I am not using us composites tinting pigments for the same reason. I will pick up some pigment locally and see how it comes out. Thanks, Mike

Shine, did you reduce the epoxy or use it unthinned? Looks great

no, I just used our private label epoxy and epoxy pigment. No reductions or dilution needed
