Epoxy resin
- easy to work with
- many different varieties out there- easy to find locally
- softer than polyurethane or polyester resins
- good brands: envirotex, devcon 2ton, colores (rio)
- check the labels! some are waterproof, others water resistant.
- look at both pot time (which is your working time) as well as total curing time
- usually a 1:1 mix, more wiggle room on the measuring than other types
- harder plastic
- takes finishes better than epoxy
- easy to work with
- check the pot time and cured color when ordering
- much shorter working time than epoxy
- measurements must be exact especially for clear
- usually a 1:1 or 1:10 mix
- polytek and smooth on are the 2 major brands
- smooth on is available at some art supply stores
- much less viscous during pot life enabling more detailed castings
- there have been several reports of skin sensitivity to the clear smooth on products. test for yourself to see if you are irritated by them
- very toxic
- hard plastic
- takes finishes well
- easiest to get optically clear castings with
- not allowed in the school studio due to fumes associated with it.
- most exacting in terms of accuracy in measuring
