Description
The Polyurethane Expanding Foam system of 9703 (PART A) / 9706 (PART B) has been formulated to produce a free rise core density of 15.0 pcf.
It is designed for applications where a possible need for absolute highest strength is required and has a density that is comparable to a rock and would only be dented with a hammer or equivalent.
Please Note: The max operating temperatures of the 15lb expanding foam is 212˚F but for that specific application we do NOT recommend exceeding the temperature of 160˚F for making composite parts in an oven.
Please note:
Per the manufacturer, the thinnest pour of correctly mixed chemicals to get a good foam reaction is 1” of material; on the thickest side, it is not recommended to exceed 6” of material. Anything within that range should provide a good reaction of the two components if they are properly mixed in the correct ratio using the right mixer and speed (1800 – 2000 RPM).
