Z-Snap epoxy is a flexible, toughened epoxy infiltration system specifically formulated for Z Corporation for use
with zp
®
250 powder. Parts made from zp250 powder and infiltrated with Z-Snap epoxy exhibit the appearance
and snap fit characteristics of plastic. These parts can be easily sanded and finished. For detailed instructions
on how to use Z-Snap epoxy with zp250 parts see Chapter 3, Using zp250 Powder.

ENERAL APPLICATION NOTES
• All part surfaces should be clean, dry and free of contaminants prior to applying Z-Snap epoxy.
• The part should be oven dried for 2 - 4 hours at 150°F - 200°F (65°C - 85°C), depending on part volume and
wall thickness, to drive off any excess moisture that remains in the part after depowdering.
• Z-Snap epoxy can be sprayed, brushed or drizzled onto parts. Multiple thin coats applied liberally during the
resin’s working time will produce maximum infiltration depth.
MIXING INSTRUCTIONS
• In a clean, plastic, non-porous, container mix Z-Snap Resin to Hardener in a 2:1 ratio by volume, 100:47 by
weight. Mix the two parts thoroughly for 2 minutes, stirring in a figure eight pattern, being sure to scrape the
sides and bottom of the container.
• The material has a working time of 85 minutes in a 450 gram mass at room temperature. Mix only what you
need. Please be aware that the mixed solution will increase to a maximum temperature of 122°F (50°C)
after 40 minutes.
PLEASE NOTE: The gel time decreases when preparing quantities of material greater than 450 grams.
CURING INFORMATION
• Infiltrated parts should be pre-cured at ambient temperature for 30 minutes.
• Cure the infiltrated part for 30 minutes at (120°F) 50°C then 2 hours at (165°F) 74°C on a non-stick (wax
paper, Teflon, polyethylene, etc.) material or it will adhere to the surface it is sitting on while curing.
PLEASE NOTE: Z-Snap epoxy should not be cured at temperatures greater than (165-°F) 74°C and longer
than 3 hours because flexibility may decrease, making the parts more brittle.
CLEAN UP
• Any remaining mixed infiltrant beyond the working time should be kept in a well-ventilated area to avoid
fumes. Clean up of the spraying apparatus is simple with solvents found at a local hardware store such as
acetone or denatured alcohol.
