Hot Stuff Original is our thin CA glue with a viscosity (3cps) similar to water and no surface tension. When you have parts that fit exactly together, first get them in position, then run this instant glue along the crack, and it will wick right in. If you have tight-fitting joints of non-porous material, Hot Stuff thin CA glue will give you the best results as it will not create any extra space between the pieces, and since you get the parts aligned before applying this instant glue, you can be sure they will be perfectly in place when the glue cures

Super T MEDIUM gap-filling CA glue has a viscosity (of 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 the accelerator to the other part, then push together and hold tightly for around 30 seconds.

Special T THICK gap-filling CA glue (green label) has a viscosity (1150-1500) similar to honey. This super glue works great when you use it to bond both porous and non-porous parts, and it can fill larger gaps than our 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 materials as with our other CA glue- wood, metal rubber, nitrile, composites, and 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 fit otherwise, cover and protect jagged edges, and improve the look of the surface.

NCF Stone is designed to be used specifically with natural stone such as granite and marble, especially light-colored varieties of granite which are prone to discoloration when too much of our NCF Quick is used. We have tested this product on a variety of these sensitive granite types, and they did not discolor even when completely soaked with NCF Stone. However, NCF Stone should still be applied as a light mist- if the parts are becoming visibly wet, you are applying too much.

We recommend using NCF Stone with all granite and marble, but especially with light-colored stones that may discolor with NCF Quick. It is a more expensive product per ounce than NCF Quick, but you do not have to worry about potential discoloration. There is no benefit to using this accelerator on stone types besides granite and marble, so we recommend using NCF Quick for other stone types.

NCF Stone comes in a 6oz aerosol can. This accelerator is active for several minutes, so you can spray several pieces at once if you are making multiple bonds.
