If you wish to combine multiple litre of resin and hardener without delay, you'll want to make use of a adequately big container in which you can mix the mass evenly for a number of minutes using a drill that has a stirring attachment.
The response of epoxide groups and isocyanate teams can result in two predominant sorts of ring constructions: isocyanurate rings (by trimerization of isocyanate groups) and oxazolidinone rings (with the reaction of an isocyanate team having an epoxide group).
Air bubbles while in the cured resin are a typical trouble. They are able to materialize from mixing difficulties, speedy pouring, or not degassing the resin. To repair this, combine the resin and hardener perfectly. Also, use a vacuum chamber or perhaps a torch to remove air.
