Pro CA Glue Thick 1/2 oz (GPMR6013)

Pro CA Glue Thick, 1/2 oz is a thick-viscosity cyanoacrylate adhesive designed for fast, reliable bonds in hobby and modeling projects. The thicker formula helps it stay in place, fills small gaps, and wicks into wood surfaces—especially balsa—for a strong hold in seconds.

Cyanoacrylates, commonly called CA glues, are moisture-activated adhesives that cure when surface moisture and ambient humidity trigger polymerization. Pro CA is described as surface-insensitive, enabling good adhesion across a range of materials and is especially effective on balsa wood; for some applications, an activator may be used to speed curing and increase bond strength.
