Product description
Dow one-part moisture cure adhesives are generally cured at room temperature and in an environment of 30 to 80 percent relative humidity eliminating the need for curing ovens and the associated costs of energy and capital. Greater than 90 percent of full physical properties should be attained within 24 to 72 hours and varies according to product. These adhesives cure from the exposed surface inward at a rate of ~0.25 inch per seven days; mild heat below 60 °C may be used to accelerate cure. They retain their physical and electrical properties over a broad operating range.
Recommended accessories
- Dispensing guns: manual (WEICON 10000441), pneumatic (LOCTITE 97002)
- Nozzles: standard nozzle (8 cm), long nozzle 175 mm
