Product to avoid air bubbles in hand laminating

Hello, I use to avoid the air bubbles from resin when hand laminating a product from HP textiles (http://www.hp-textiles.com/shop/product_info.php?info=p240_100ml-system-degasser---hp-bel51-100.html), but I want to know waht kind of liquid is. Anyone know it?

You can use acetone instead.

Never use Acetone in Epoxy! The Degassing additive is a reacting one! Works perfect.

where I can buy the degassing additive?

I would crazy if use acetone, that only cause large pinholes.

The one from HP Textiles you posted is the ine I ment and use.
