Suitable for surface wound bonding, protection, holding a sensor or other device on the tissue. LAB SUPPLIES Kwik-Gard ™ Scotch-Weld 2216 Structural Epoxy Kwik-Gard is specially packaged Sylgard 184 silicone for quicker and easier application, eliminating the messy procedure of preparing the mixture before application. Its special cartridge controls the precise mixing ratio to ensure proper curing. The disposable tip mixes resin and hardener as they are dispensed. Since no air is introduced during mixing, the resin does not need degassing for most applications. The mixed silicone is applied directly to the site, reducing preparation time and material waste. Each Kwik-Gard cartridge contains 37 mL of resin and hardener. The dispensing tip has a dead volume of 0.75 mL. KWIKGARD Kwik-Gard Start-up Kit (incl. dispenser, 1 cartridge, 5 tips) KWIKGLUE Kwik-Gard Refill (2 cartridges, 10 dispensing tips) KWIKMIX Dispensing Tips (pkg of 10) KWIKGUN Kwik-Gard Dispenser Probably still the best epoxy for bonding plastic, often used as the benchmark for testing the binding strength of other adhesives. The slightly rubbery texture also makes it less easy to break off. It is the only epoxy known that can bond PEEK. Color: gray. Cures at room temperature. Shipping weight: 1 lb.
