R-45HTLO Polybutadiene Resin

We've chosen to offer R-45HTLO instead of R-45M for a number of reasons. It has a slightly higher functionality, which results in a higher crosslink density with the better room temperature curatives (like E 744 described below), without resorting to other ingredients that can adversely affect the cure chemistry. It also allows you to use higher percentages of plasticizer without the propellant becoming too soft. OH values generally range from 0.80 to 0.86; the manufacturer's reported value is printed on the container label. 1 gallon bottle.
