Ortho Lse

[Peter16]

I have just purchased a 20L drum of ortho lse resin. How does this stuff differ to the usual polyester resin? I had intended to get polyester but picked up the wrong drum. Is this the type of laminating resin that will never cure and stay tacky? their for is not suitable for final lay ups. as described here under finishing resins http://forums.iboats.com/showthread.php?t=286013

As far as I know it will be just fine. Used all the time for making boats. It will cure just fine with a 1.5% mekp ratio. If you don't want the final layer to be tacky add some wax to it. All poly resin remains tacky unless you add wax to the final layer. this will give you info on the product.

Re: Ortho Lse

You actually don't want the type of resin that cures tack free, it creates more work for you. The wax is an additive that you can buy at most places that sell fiberglass products, you only need to add it to the final layer.

Most people don't use it, but it's cheap and is nice for a quick tack free surface. Most resins will become tack free on their own after a few days, but the type you have may stay tacky a bit longer, this helps if you want to apply another layer.
