RB301 can be cured with carboxylic polyester or acrylate. The acid value ranges form 25-45mgkoH/g. In order to minimize the yellowing the appropriate resin should be preferred in formulation. A certaion amount of a degassing additive such as benzoin is, however, generally recommended to prevent micropinholing due to the producion of water in the crosslinking reaction. Typically cure schedules are required to develop full coating properties ranging from 5min 2000, to 25min at 1500, generally,15min at1800 is preferred. The reference formulation is shown in the following.
