Premixed and Frozen Resins
Kitpackers is a leading supplier of premixed and frozen (PMF)
resins. Premixed and frozen refers to the blending, packaging
and freezing of two components resin systems. Kitpackers
provides epoxy, silicone, urethane, and polysulfides in various
syringes and
cartridges premixed and frozen.
PMF packages are the ultimate in convenience and reliability as
all the operator has to do is thaw and dispense. The end user
can use our PMF packages with total confidence knowing that
Kitpackers precisely weighs, mixes, degasses, and packages their
two component resin, and then flash freezes it at -80C.
Syringes from 1CC to 55C are the
most common PMF packages, but larger
cartridges from 2.5oz to 32oz are possible with some resin
systems in certain applications. We also provide PMF materials
in jars and
cans.
The end user must have a -40C or lower freezer available in
order to store these PMF packages shipped to them on dry ice
over night. Our PMF insulated cartons require special handling
when received, and are labeled accordingly. They must be
inspected for presence of remaining dry ice and then promptly
transferred to the -40 freezer for storage. Handling, storage,
and thawing instruction are available
PMF Instructions.
Kitpackers specializes in the modification of resin systems
particularly for PMF packages as it is simple to add a third or
fourth ingredient to the two component resin system during the
mixing process. For example, Kitpackers stocks 14 different
sizes of precision glass spacer beads and adds them to a variety
of Dow Corning, 3M, and Henkel products. Further Kitpackers can
add adhesion promoters, pigments, fluorescent indicators, as
well as fillers to increase viscosity, thermal conductivity, and
improve other physical properties.
Kitpackers has the capability to centrifuge syringes 30cc and
smaller after filling to ensure that the syringes are totally
air free. The premixed material must have sufficient pot life to
allow for the extra centrifuging step and some materials are not
suitable for centrifuging.
