Product Information

Jotamastic 90 Standard Comp B – 1L Hardener for Jotamastic 90 Epoxy Coatings

Jotamastic 90 Standard Comp B is the essential curing agent (Part 2) for use with Jotamastic 90 epoxy mastic coatings, designed to activate and complete the two-component system. When mixed with Jotamastic 90 Comp A (available in Grey, Black, Aluminium, and Base 3 tints above), this hardener creates a high-performance, surface-tolerant coating system ideal for Ireland’s toughest marine, industrial, and offshore environments.

Formulated to cure reliably in suboptimal conditions—including damp surfaces and cold climates—Jotamastic 90 offers excellent abrasion resistance, high solids content, and long-lasting corrosion protection. Whether you're applying a primer, mid coat, or finish coat, Component B ensures your epoxy system performs to the highest standard.

⚠️ Please note: This is Component B only. It must be mixed with the appropriate Jotamastic 90 Comp A variant (linked above on this page).
