Electrically Conductive Silver Epoxy Two-component silver-filled epoxy for electrical connections which cannot be soldered, such as Ag/ AgCl pellets. This widely used silver-filled epoxy features low viscosity and smooth flowing character. Pure silver is dispersed in both resin and hardener. Cures in 15 minutes at 120 °C. Mix ratio 1:1. May be premixed and frozen for later use. Shipping weight: 1 lb. (0.5 kg) Silicone RTV adhesive (non-acidic) Because it is non-corrosive, this material is ideal for use on metal, for encapsulating small circuits on connectors. After cure, will withstand -55° to 200 °C. No mixing required. Shipping weight: 1 lb. (0.5 kg) Silicone RTV adhesive Clear silicone sealant provides good bonding to plastic. After cure, will withstand -55 to 200 °C. No mixing required. A handy, general purpose laboratory sealant. (Releases acetic acid during curing.) Shipping weight: 1 lb.

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 silicones is short, reliable and reproducible thus eliminating potential costly guesswork when using other tissue adhesives. Furthermore, the curing process does not produce heat, which can otherwise cause tissue damage. WPI’s silicone elastomers are much less toxic than dental silicone because they contain no surfactant additives. 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 was shown not to cause any effect on nerve activity in highly sensitive peripheral nerves. Both elastomers cure on contact with the tissue. Currently, WPI provides rapid-curing silicone elastomers in two different formulas: 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. 10 mixing tips included Kwik-Sil 1:1 2-10 minutes 15,000 90 ppi 650% 30 translucent 1x1015 0.5 lb Kwik-Cast 1:1 2-3 minutes 10,000 44 ppi 60% 36 green 1x1015 0.5 lb LAB SUPPLIES KWIK-CAST & KWIK-SIL SPECIFICATIONS Unmixed Mix Ratio Working Time, typically Viscosity, cps After Curing 24 hours: Tear Strength Elongation Durometer (shore A-2) Color Volume Resistivity, Ω/cm Shipping Weight Kwik-Sil™ is a translucent silicone elastomer adhesive with medium viscosity.
