    Default Tinting Interthane Urethane

    I have a gallon of Blue White Interthane 990 which I want to tint to light blue for the tender/sailing dory. Has anyone got any thoughts on a blue which could be added to it?

    I have used 990 extensively and it is incredible paint and easy to use. I keep looking at this gallon on my shelf and would like to put it to use.

    Thanks in advance

    I have no personal experience tinting paint - a quick Google search turned up 'https: // rawlinspaints,com' which discussed color availability. (No affiliation) They are overseas, local resources may be available.


    Good luck,

    Interthane 990 seems to be an an Interlux (Akzo Nobel) product sold in some European countries, but not in US.
    Id ask the manufacturer.

    I've used small amounts of the same paint base in a color I wanted to move toward: ie a bit of dark blue of the same paint (or paint base if multi part) to get a light blue.. Not approved by anybody, but its worked fine. Of course if you cant get a small amount of the same paint it doesn't help...

    Yep, this ^.

    Given the nature of two-part urethanes I'd agree that the best choice would be using another color of the same product to get the color you want to use. Won't take much dark blue to turn a can of white into one of light blue.

    Whether so-called "universal colorants" any paint or hardware store has on hand would affect the urethane chemistry if used as colorant is way outside my area of expertise, but you might put the question to the A-N tech folks, see what they come back with.

    where did you find interthane? it was way better than perfection, (which interlux replaced it with). but it hasn't been available here in years... before you try to tint it, make sure the hardener hasn't gelled up...

    I have had it for years. I took extra hardener knowing it would gel. I used another batch which I had tinted years ago on the hull of my tender, but the store that tinted it is long gone.IMG-3809.jpg

    Thad, I used to work on tugs where we used 100s of gallons of 990 every year, and our ship fleet probably used 1000s.

    They had problems with the stuff I think in the early 90s while adjusting to Ca. low VOC laws. There was a period where the solids would cause sagging on verticals, but after they got it right, the quality was incredible. It wears like iron. I tip and rolled the bridge deck on my trawler and then wet sanded and polished it. Our International rep said that you can't sand and buff it, but it gleamed and still looked good 10 years later. Seagull crap just washed off, with no stain. The stuff is amazing.
