Gel is a high performance Aviation Grade sealant emulsifier in gel form
designed to remove polysulfide and other sealants from a variety of
surfaces and geometries. PolyGone 300-AG Gel meets the requirements of
Boeing D6-17487, except for ASTM 502 Paint Softening and meets Douglas’ CSD#1, except ASTM 484, Acrylic Crazing.
Gel is a proprietary formulation designed to penetrate, break down and
emulsify tenacious sealants. Once broken down, the sealant is suspended
to prevent redeposition and enable easy rinsing.
PolyGone 300-AG Gel is for use at room temperature (68°F-80°F). Apply
the gel using an acid brush or plastic spatula onto the target area.
Periodic agitation (every 30 minutes) is required to remove the
digested sealant and exposes underlying layers to fresh PolyGone 300-AG
Gel. Repeat this until the surface is free of sealant. The gel must be
used at full strength. Dilution will deactivate the emulsifier.
However, you may thin the gel if necessary with liquid PolyGone 300-AG
for your particular application. The unused portion may be resealed in
the container and stored in a cool dark place.
For large areas, a lint-free cloth is recommended to remove the bulk of
the product. PolyGone 300-AG Gel is water-soluble. Although
pure water may be used to rinse the product, rinsing with a low
surfactanated emulsifier such as eOx®, also available from
RPM Technology, will improve rinsing via a “sheeting” effect, reduce
sealant redeposition, and reduce water usage. In cases where water is
not preferred, a compatible solvent such as IPA or acetone may be used.
300-AG Gel is metal-friendly. The formulation is non-ionic and
non-reactive. Metals such as Cu, Fe, Al, Zn, and Ti have been tested
with PolyGone 300-AG Gel with no detected metal loss. However,
PolyGone 300-AG Gel attacks many types of polymers and plastics.
Polyvinyl chloride (PVC), polyvinyl alcohol, and similar plastics should
not be treated with PolyGone 300-AG Gel. Many elastomers are also not
recommended. RPM Technology, recommends the following plastics for
application and storage, Polypropylene, Poly Olefin, Polyethylene (low
and high density), Teflon, and Butyl Rubber. Testing is necessary to
demonstrate full compatibility.
Recommend personal protective equipment (PPE) includes safety
glasses/goggles and nitryl or butyl rubber gloves. Aprons may be used
to protect clothing. Do not use gloves made from latex or
PolyGone 300-AG Gel contains a blend of polar organics and a gelling
agent. PolyGone 300-AG Gel has a low inherent toxicity and at diluted
levels, is essentially non-toxic to aquatic life. The material is
readily biodegradable and does not bioaccumulate.
PolyGone 300-AG Gel must be stored in a cool and dry environment away
from light and incompatible materials. The recommended storage
temperature is between 50ºF-80ºF (10ºC-27ºC). Under these conditions,
unopened containers of PolyGone 300-AG Gel have a 1-year shelf life.
Securing the container cap extends the life of the unused PolyGone;
although the length of time the material will remain active cannot be
no halogenated, reactive, or other EPA regulated components.
Conformance with Federal, State, and Local disposal regulations is
required. Diluted PolyGone can be disposed of by discharge to a sewage
treatment plant with prior approval. Used PolyGone may need to be
disposed of as organic solvent waste depending on the sealants and
contaminates removed. PolyGone has a high BTU value and waste can be
managed through a fuels-blending program.
Gel is available in individual 6-oz. poly containers, 12 x 6-oz. cases, and
5-lb poly buckets.
