HENKEL CORP.: Two-Part Silicones (3/23/09)
Loctite Ultra-Clear Two-Part Silicones cure to handling strength in 15 minutes and offer shelf lives in excess of 12 months at room temperature. These adhesives rapidly build strength and reliably support heavy components such as windows, skylights, outdoor signs and displays. Three ultra-clear, non-corrosive silicone products are currently available.
Loctite 5620TM is a fast-curing silicone that cures in 30 minutes at room temperature. Loctite 5623TM is a tack-free, tough silicone gel that cures in 24 hours at room temperature or in just one hour at 100ºC. Loctite 5625TM is a soft, re-enterable gel silicone that allows for potting compound repair and cures in 24 hours at room temperature or in one hour at 100ºC. All three products can be manually or pneumatically dispensed.
Resisting temperatures up to 230ºC, these non-corrosive silicones cure through large gaps and enclosed bond lines, require no primers and offer low odor dispensing. With elongations as great as 240%, these highly flexible materials withstand extreme vibration, flexing and thermal shock. They are designed to resist UV rays, water, outdoor temperature variations and most cleaning solutions. These two-part formulations provide consistent, uncomplicated mixing, with simple 1:1 mix ratios versus competitive 10:1 mix ratios.
