How much epoxy per pair of skis?

SkiTheNortheast · Post by **SkiTheNortheast** » Wed Feb 08, 2012 2:53 am

I know it varies depending on what you use but just post what you are using and how much epoxy you use per pair.

I would like to get entropy but I want to figure out how much I need to order. I don´t want to over/underorder.

Thanks

About 1/2 kg of resin per pair with 750 gsm (22oz) glass

180 skis 100mm underfoot - 50% more if I'm sloppy

so a gallon of resin will do about 8 pairs?

I typically mix 800g for a 185 cm ski. I may try to get away with less. Something around 700-750g since I usually have about 100g give or take left over.

i'm around 900-1000g per pair using entropy, working on cutting this back. need more experimenting, maybe a separate wet layup table. why not buy a small kit and test it out?

also, i see your in NH...these guys sell entropy resins, can probably save on shipping coming from RI versus entropy hq in Cali

whoa thanks a ton for showing me that

it's sort of a one stop shop because they have a lot of composite materials too, although they didn't have the entropy CPM resin which is their compression molding specific resin. I'm not sure if any of the other resins would work, does it have to be a compression molding resin specifically or can it be any resin?

WOW thx
Jamestown distributors not too far from me

. If they have it... probably Comprising One have Entropy too. Only Jamestown website showing no super sap CPM.
100/1000 for press without heat?

I would only use heat curing epoxies. Non heat-cured epoxies are like 1/3 as strong as heat cured.

yeah i use the 100/1000 for room temp cures, no heat yet for me

For now I don't have plans for blankets because I'm not an electrician and somewhat uncomfortable doing electrical work like making PID controller.... it shouldn't be difficult to make the blanket....anybody up to group build of blankets?

I mean I live fairly close to you so I would be down, but I won't be available to do anything until late June, if you want to wait that long

I can get 4 -5 pair of skis out of a gallon of resin, 1qt hardener. I've been using QCM epoxy.

I'll have to check out Jamestown pricing for Entropy. I'm in MA. I could take trip down to RI and make a day trip out of it.

I think Jamewstown is just an online supplier, and they don´t have the cmp resin, I´m not sure how good the other ones are

My rule of thumb is 1:1 (not 100% exact, but you get a good wet-thru)
ex. 100g FG = 100g epoxy

Carbon fiber draw more, 1:1,5 (ca...)
