Our vat of 7100 recently became too viscous to use. Thinking back we believe this has been a gradual change in resin properties that perhaps began affecting our builds 6-9 months ago. We are currently negotiating with DuPont for a refill.

> Is there anybody has experience in problems encountered from Somos 7100. We use 7100 over one year and now the visicosity of the resin is realy high. Just like some cream and is sticky.
