Technical Data

Typical Physical Properties

Property Value
Color Brown
Density 0.95 g/cm³ (0.034 lb/in³)
Open Time 50 seconds¹
Flash Point >200°C (>392°F)²
Viscosity 5,200 cP at 191°C (375°F)³

¹Open time is the maximum time between the application of the adhesive and joining the parts. Data based on a 3.2 mm (1/8 in) semicircular bead on non-metallic substrates at 24°C (75°F). Higher environmental temperatures and/or larger beads will lengthen open times.

²Cleveland Open Cup.

³Brookfield Thermocel Viscometer in Centipoise using a #27 Spindle @ 10 RPM.
