HST-4T is a 2 ounce bottle of Special T thick CA glue from Satellite City.
Special T THICK gap-filling CA (Cyanoacrylate Adhesive) glue (green label) has a viscosity (1150-1500 cps) similar to honey. This glue works great when you use it to bond both porous and non-porous parts, and it can fill larger gaps than the Super T medium CA glue. It is best used to glue parts that are missing pieces or don't fit very well together. You can bond the same meterials as with the other CA glue - wood, metal, rubber, nitrile, composites, many types of plastics - and Special T is effective even when a poor fit makes parts look impossible to bond. The gap-filling capability is very useful when there is a large chunk missing from a surface - filling that space with Special T can preserve the structural integrity, seal the area from moisture and contaminants, bond something to the exterior that would not fix otherwise, cover and protect jagged edges, and improve the look of the surface.
If you have pieces that do fit well together, then this is the wrong CA glue to use, as it will create extra space in between pieces. However, if you have a big chunk missing from a wood or stone surface that you need to fill in, or if you are gluing poorly-fitting materials, this is the best instant glue to use. It is also our easiest CA glue to ue because Special T doesn't require a good fit and because the high viscosity makes it run much less than the thinner instant glues. Special T cures slower than the other CA glues (roughly 20 seconds with accelerator and 60 seconds withouth accelerator when pressed firmly between two parts), so you also have more time to assemble your pieces.
Special T CA glue is used for woodworking-related repair and assembly, setting stones and attaching beads, repairing damaged areas in granite countertops, attaching tips to pool cues, gluing finger inserts into bowling balls, repairing damaged model airplanes and cars, assembling bone fragments, putting together and repairing dental bridges and dentures, and countless other applications.
It is recommended to use the NCF Quick CA glue accelerator to speed up the cure time and ensure a complete cure of the bond. This is especially important with Special T CA glue because of its slower curing time relative to Hot Stuff and Super T and also because if Special T is being used for gap-filing and is not subjected to firm pressure between two parts, it will likely take at least a few hours to cure without accelerator.
When filling gaps, it is always best to apply one layer of glue and cure it with NCF Quick accelerator before applying the next layer. Filling a large gap without curing each layer will result in a delay or failure in the curing of the bottom layers. Don't be afraid to overfill a gap-you can easily remove the excess with a razor blade after it is cured or sand it down if necessary.
Store unopened bottles in the freezer to extend shelf life. Bottles of super glue (any brand) which have been opened will experience a shorter shelf life if they are continually taken out of and put back into cold storage. Shelf life is 6 months for 1/4 ounce, 9 months for 1/2 ounce, and 1 year for 1, 2 and 4 ounce bottles.
