For bonding liquid crystal modules (LCMs) to housings and brackets on handheld devices such as smart phones and tablets with displays of any size, the line of Loctite® Structural Adhesives allows thinner profile device designs with extremely narrow edge borders. Thermally stable and humidity resistant, Loctite® HF (halogen-free) Structural Acrylic Adhesives offer durable bond lines that seal against moisture or contaminants entering the assembly. Once cured, these adhesives resist damage from impact even on edge borders.
Four products are available: Loctite® HF8000(TM), Loctite® HF8150R(TM), Loctite® HF8800(TM) and Loctite® HF8075LV(TM). With varying viscosities for different assembly requirements, Loctite® HF products are two-component adhesives that fixture in 2 to 8 minutes at room temperature once mixed. While all four formulations can be cured at room temperature, elevated temperatures accelerate cure times. Loctite® PUR Hot Melt Adhesives are fast fixturing, single-component thermoset adhesives that resist heat, humidity and moisture. High strength and halogen-free, Loctite® 3540(TM), Loctite® 3541(TM) and Loctite® 3542(TM) easily bond plastic, metal and glass substrates, fill gaps in assemblies and fixture in 1 to 2 minutes.
