Cure Method: Moisture Cure
Curing Conditions: Cure speed will vary with temperature, relative humidity, depth of material and presence of moisture. Some applications may require special surface preparation. At 21 - 25°C, 45 - 55% relative humidity, typical cure depth is 2mm in 24 hours. Requires more time to cure in colder or lower humidity conditions.
General Instructions: For best performance bond surfaces should be clean, dry and free of any contaminants and oils.

Apply a continuous and even bead of silicone to one surface.

Assemble parts immediately. Remove excess material at once.
