Kato Poly Paste is a heavy-bodied adhesive used to attach cured and uncured pieces in any combination. Unlike other adhesives, Poly Paste fuses two pieces of polymer clay together and creates a permanent bond. Ways to use Poly Paste include repairing cracks, creating texture and gilding when mixed with mica powders. It will not run when applied to vertical surfaces. Excess Poly Paste can be removed before baking or after baking by trimming with a knife.
In order to take effect,
Poly Paste must be cured. It may be cured between 265F and 325F for 10-30
minutes; time and temperature depends on the recommended curing temperature of the polymer clay
