New TiThese mixing tips may be used with KWIK-SIL or KWIK-CAST.p Design

Kwik-Sil and Kwik-Cast now come with a new tip design. The new tip is engineered to minimize leakage.

Curing Time

The properties of this bio-compatible adhesive make it exceptionally useful for neuroscience applications, peripheral nerve studies and similar biomedical applications. These new silicone elastomers also eliminate the mess and time involved in pre-mixing other commonly used formulations (such as Wacker SilGel® and Sylgard®). Each silicone elastomer is packaged in a double barrel syringe and is automatically mixed when pressed out of the mixer tip provided. It can then be applied directly to the tissue without further mixing. The curing time of these silicone adhesives is short, reliable and reproducible. This eliminating potential costly guesswork when using other tissue adhesives. The curing process does not produce any heat, which can  cause tissue damage. WPI's silicone elastomers are much less toxic than dental silicone, because they contain no surfactant additives.

Low Toxicity Adhesive

WPI's silicone elastomers are based on recently developed vinyl terminated siloxane and platinum complex catalysts. They exhibit exceptional low toxicity before, during and after curing. The traditional RTV silicone systems produce either acetic acid or alcohol during condensation. These compounds are toxic to living cells. In contrast, the only by-product of condensation from WPI's elastomers is a small amount of hydrogen gas, which has no effect on nerve activity in highly sensitive peripheral nerves. This silicone elastomer cure on contact with the tissue. Currently, WPI provides rapid-curing silicone elastomers in two different formulas:

  • Kwik-Sil is a translucent silicone elastomer adhesive with medium viscosity. It has good adhesion and mechanical property (tear strength and elongation). The very short curing time (approx. 1 minute) make it especially useful for moving preparations.
  • Kwik-Cast™ is a very low viscosity silicone elastomer sealant. It is able to fill small spaces around nerves and creates a continuous mass ensuring long-term recording stability. Kwik-Cast is color-coded so mixing is foolproof. It can be applied and cured underneath mineral oil. The slight longer curing time (approx. 3 minutes) makes it more suitable for stationary preparations and in vitro tissue studies.

600022 Replacement Tips

Q: I want to use Kwik Sil in my "imaging" experiments in rats. How do I get rid of the bubbles completely, or at least reduce them as much as possible?

A: The bubbles are hydrogen gas that is released as a by-product of the curing process. The cure happens in such a short period that the gas can't escape. A slower cure time might help. To slow the cure process, cool the material before mixing.
