A one part, high temperature curing, void filling compound. This product has the same formula as Scotch-Weld™ 3500–2 B/A, but it is the deaerated one part version. PMF stands for Premixed Frozen. It is designed for honeycomb sandwich constructions where heat resistance is needed, honeycomb splicing and reinforcement, mismatch area filling, and inserts bonding.
Offers the following advantages: High performance from -55°C to + 175°C, convenient 1:1 mix ratio by weight, thixotropic for ease of application, long work life at 15-25°C, low volatiles loss during cure. Cures from 120°C to 175°C in one hour. Low cured density. Excellent water and chemical resistance. Room temperature storage of the two compounds.
