HST-4 is a 2oz bottle of Super T medium CA glue,
Super T MEDIUM gap-filling CA glue has a viscosity (200-300 cps), similar to syrup. This super glue is perfect for gluing somewhat porous materials and pieces which have small gaps between them. Super T instant glue cures at a slower speed (10-25 seconds) than Hot Stuff. You can bond wood, metal, rubber, nitrile, composites like carbon fiber and Kevlar, many types of plastics, and more. To bond two parts together, apply the Super T CA glue to one part and accelerator to the other part, then push together and hold tightly for around 30 seconds.
