Can epoxy novolac resin be cured at ambient conditions?
In the present study, the epoxy novolac resin was cured at ambient conditions using an aliphatic aromatic polyamine, MXDA adduct, where the curing occurs when the active hydrogen in the primary amine reacts with the epoxide group via a ring opening (see Fig. 5) [ 12 ].
Can epoxidized novolac resin be used in polymer networks?
In addition, epoxidized novolac resin (ENR) has high thermal stability, fatigue resistance, and anti-corrosion property. Therefore, application of ENR with PU in preparation of polymer networks has advantages of both groups of materials [ 23, 24 ].
Can lignin replace pigments and fillers in epoxy novolac coatings?
In this study, to replace pigments and fillers of an epoxy novolac coating, technical Kraft lignin particles were ground and size fractionated (i.e., sieved), and used for formulation work.
How to prevent plasticizer migration?
Once you understand the level of plasticizers in your materials, you can decide whether or not you need to be doing something about it. There are three main ways you can prevent plasticizer migration. Use specialist plasticizers – Plasticizers with a high molecular weight or a high degree of branching will prevent movement.
Are epoxy novolac coatings corrosion resistant?
To evaluate the corrosion resistance of the coatings, all samples were exposed in a salt spray chamber and the performance was compared with epoxy novolac coatings containing either iron oxide pigment, no pigment (i.e., neat epoxy novolac and DGEBF), or a range of pigments (i.e., a commercial anticorrosive coating).
Can a plasticizer migrate out of a surface?
Coating the surface – The plasticizer cannot migrate out of the surface if there is a coating that will not allow it to pass through. Now that you know about plasticizer migration and why it causes problems, it’s time to decide whether it can affect your application.
