Complete Huntsman Heatlok HFO High Lift closed-cell spray foam system. Includes the A-Side (Huntsman ISO – 520) and B-Side (Heatlok HFO High Lift resin), sold together as one set.
The Huntsman Heatlok HFO High Lift Closed-Cell Set is a complete Huntsman Building Solutions Heatlok HFO High Lift closed-cell spray foam system: the A-Side (Huntsman ISO) and the B-Side (Heatlok HFO High Lift resin), matched and sold together. It is an HFO-blown, low-GWP closed-cell foam that insulates and works as an air barrier, vapor retarder and water-resistive barrier, above and below grade. Full specs for each side are in the A-Side and B-Side tabs.
Review both safety data sheets before handling. The A-Side contains MDI isocyanate and can cause respiratory and skin sensitization: use a supplied-air respirator when spraying, chemical goggles, chemical-resistant gloves and full skin coverage. Foam must be separated from the interior by an approved thermal barrier.

The Huntsman ISO is the A-Side (isocyanate) component used with Huntsman Building Solutions spray foam systems (A-PMDI isocyanate, sold by Huntsman as Rubinate M / Suprasec 5005).
The Huntsman Heatlok HFO High Lift resin is the B-Side component of the system. Its chemistry sets the finished foam: closed-cell, HFO blown, built for thick passes.
