Product Overview
ZyCoat ZyBar 11004 is a high‑temperature, modified polymer coating designed for demanding automotive applications. Available in a 4 ounce (16 fl oz) satin‑finish bottle, the Midnight Black formula combines rust resistance with exceptional heat tolerance—rated to over 2100 °F ambient and 1600 °F substrate temperatures. Its polymer base provides a hard, ceramic‑like surface (7.9 pencil scale) while maintaining flexibility for thermal expansion. The coating offers excellent coverage based on film thickness and bonds to itself for easy touch‑up work.
