It is a good product, but is too dense for intricate mold and it not tottaly bubble free. Consider a vacuum system.

Update 6-FEB-2023: Now reading of an inhibition issue with some SLA resins not cured for many hours. Will top-coat molds with non-inhibiting coating and re-cast. Will update rating upon results. Original Review: Instructions followed to a tee: -Used identical single-use syringes from the same batch to precisely measure each part. -Combined and mixed thoroughly for 5 minutes. -Poured into open top 3D Printed "sheet" molds (1.2mm thick with various top-down areas.) Results: -Tops cured well - looks good so far... -Peel up sheet - Still uncured where not exposed to air. -Sticky mess I will be purchasing a different silicone for our use, as 3 days+ is not an acceptable when expecting 3 hours.
