HH SUMMER 90 BLUE, PART B, TOTE

The HammerHead Summer Hardener 90 Blue (Part B) is a blue‑tinted curing agent formulated for use with HammerHead’s Epoxy Resin Base Yellow (Part A) in CIPP lateral lining applications. The Summer 90 profile provides a long working time with a moderate cure time, making it the ideal choice for extended wet‑out, longer runs, complex liners, or installations where crews need additional handling and setup flexibility. It is the slowest‑reacting option in the HammerHead epoxy system, offering the most generous working window compared to the Standard and Winter hardeners.

Mixed at the required 4:1 ratio by weight (3.3:1 by volume) with Part A, the components blend into a uniform aqua‑green color, giving installers a clear visual confirmation of proper mixing. This extended‑working‑time formulation supports consistent wet‑out quality and controlled installation pace, especially on larger or more demanding CIPP projects.
