Hi

Due to complex part etc I am now doing a part with a infusing stage and then another stage
with UD reinforcements, core etc, that I wetlay and bag.
Would the IN2 work for both applications?
The viscosity will not be a big problem as I can store it a little bit cold for the second stage.
But would the cohesion be good? (after light sanding and aceton washing)
Also, if I use fast hardener for the first stage infusion, and slow for the second stage,
would that work?

Or,
IN2 first and then IL2?

IN2 would work for both but EL2 Epoxy Laminating Resin is a better option for wetlay due to increased viscosity.

Hi, I did some body panels for a race car using Infusion. Once finished they didn't feel quite stiff/rigid enough so I decided to wet lay some soric onto the backs of the panels. I used IN2, the thinking being that it would be totally compatible and being thinner/less viscous it would wet out the soric better. It worked out really well and the finish left by the peel ply makes a perfect bonding surface.

Hi Warren, thanks,
but just to clarify, wet EL2 would work on dry IN2, ?
(due to surface finish demands I have to infuse + GC50)

Yes they are both epoxy resins and very similar in composition and formulation except one is formulated specifically for infusion.  As always, a rough surface is best for mechanical adhesion and the sooner you add the additional layers after the infusion has initially cured, the more cross linking there will be between the additional layers (not all resin is cured 100% when at the demouldable stage in a parts cure).
