Special T is our thickest accelerator with a viscosity similar to honey and greater gap-filling ability and a longer positioning time than Super T. The cure time is approximately 50-60 seconds. We recommend using the NCF Quick accelerator to speed up the cure time and ensure a complete cure of the bond. HST-4T is a 2oz bottle. Store unopened bottles in the freezer to extend shelf life. Bottles which have been opened will experience a shorter shelf life if put into cold storage.
