Peel Ply 80g
You can apply pressure against it to remove air and the peel ply will assist in keeping the structural layers in the right place. Peel ply also helps the surface cure properly by keeping the air out as air can work as an inhibitor for curing. Once the project has hardened and have removed the peel ply, not only are left with a surface that doesn’t require any additional treatment for rebonding, but if it requires additional work or shaping, it won't clog up your equipment with uncured resin.
Peel ply is commonly used in vacuum layups.
Peel ply is available in 1m lengths and is 1m wide.
