A hot-melt adhesive system that’s ideal for bonding reveals, chamfers, form liners, weld plates and other structural and architectural elements into all types of precast concrete forms is now available from Power Adhesives.
The new Power Adhesive hot-melt system consists of a line of Casttec precast adhesives and one of three TEC heavy-duty hot-melt glue guns.
Power Adhesives’ Casttec Precast Hot Melt Adhesive formulations provides superior strength against shear, which prevents elements from moving on the form as the concrete is flowing and keeps critical form inserts from shifting. It remains tacky for up to three minutes in the event more precise positioning is required. Recrystallization of the Casttec Hot Melt occurs over an eight-to-10-hour period. This delayed recrystallization provides maximum bond strength during the setup and pour stage and makes the adhesive easier to clean off the form when precast parts are removed.
The hot-melt adhesive bonds to all common material types, including wood, foam, most plastics and some metals. A fast one-step process, the system does not requiring priming, secures a strong bond that sets almost instantly and has an excellent release from form for fast cleanup.
