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.
Low toxicity 5-minute adhesives for live tissues!
· Specially formulated for WPI
· Extremely low toxicity
· Excellent moisture resistance
· Cures at room temperature
The properties of this adhesive make it exceptionally useful for neuro-
science 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 silicones is short, reli-
able 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 con-
tain no surfactant additives.
WPI's silicone elastomers are based on recently developed vinyl termi-
nated siloxane and platinum complex catalysts. They exhibit excep-
tional low toxicity before, during and after curing. The traditional RTV
silicone systems produce either acetic acid or alcohol during conden-
sation; 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 activi-
ty in highly sensitive peripheral nerves. Both elastomers cure on contact
with the tissue. Currently, WPI provides rapid-curing silicone elastomers
in two different formulas:
Kwik-Sil
TM
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
TM
is a very low
viscosity silicone elastomer
sealant. It is able to fill small
