KWIK-SIL & KWIK-CAST

Our KWIK-SIL and KWIK-CAST adhesives are individually packed with syringe and five mixing tips, which simplify use. The biocompatible adhesive is ideal for siling live tissues because of its extremely low toxicity. KWIK-SIL has a medium strength adhesion, with good mechanical properties (tear strength and elongation) that allow days of study without breaking of the bonding. Curing speed is very reproducible. KWIK-CAST is a very low viscosity silicone silant that flows easily, filling the small spaces around the nerve and leaving no channels through which peritoneal fluid can travel or short the nerve/electrode contact. It can flow into itself and create one continuous mass from underneath the nerve all the way to the top of the nerve/electrode contact to ensure long-term recording stability. KWIK-CAST may be applied underneath mineral oil. Electrodes are easily recovered after recording because of its low tear strength. Both KWIK-SIL and KWIK-CAST have a rapid cure time, and they cure without producing heat. KWIK-SIL dries clear, and KWIK-CAST dries green so you can visualize where it is applied. KWIK-SIL dries a little faster than KWIK-CAST, which takes less than three minutes to fully cure.

It is critical to select the right tools to execute the desired application. If you plan to target a very small subregion of a structure for example, you need to infuse under 1uL of viral vector bilaterally, it may be a good option to look into an ultra-precise model of stereotax. Further, it is important to pair with a proper injector with little to no dead volume—removing any confounds is very important to executing a successful surgery to obtain the desired data in your study. Further, having the proper microscopes, drills, anesthesia system, all contribute to the quality of your subjects’ recovery (if a survival surgery is being done), especially when behavioral experimentation will be part of your study.

The custom mixing tips ensure proper mixing of the 2-part elastomeres, and they eliminate the mess of mixing by hand. These tips are engineered to eliminate any leaking. The tips are keyed to the syringe, and with a 90º twist, they lock securely in place.

The newly available sterile KWIK-SIL and KWIK-CAST adhesives are ideal for both short-term and long-term studies, where sterility and biocompatibility in a surgical adhesive is required. These KWIK-SIL and KWIK-CAST formulas are sterilized under specialized conditions, that have demonstrated robust sterilization, not available in most research facilities. Sterile silicone adhesives maintain the same cure time and properties that researchers know and love from WPI’s KWIK-SIL and KWIK-CAST products. The double barrel syringe and all five mixing tips are individually packaged and sterilized.
