Henkel Corp. (Rocky Hill, CT) is introducing Loctite® Ultra-Clear Two-Part Silicones that rapidly bond dissimilar substrates, especially glass, and maintain flexibility at both high and low temperatures (-60 to 450º F).
The adhesive/sealants, which cure to handling strength in 15 minutes, offer shelflives more than 12 months at room temperature. These adhesives rapidly build strength and reliably support heavy components such as windows, skylights, outdoor signs and displays.
Loctite® 5620™, a fast-curing silicone, cures in 30 minutes at room temperature. Loctite® 5623™, a tack-free, tough silicone gel, cures in 24 hours at room temperature, or in just one hour, at 212º F. Loctite® 5625™, a soft, re-enterable gel silicone, allows for potting compound repair and cures in 24 hours at room temperature, or in one hour, at 212º F. All three products can be manually or pneumatically dispensed.
Resisting temperatures up to 446º F, 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. 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.
