An acidic, etching solution which is ideal for use
in adhesive systems for bonding non-porous
ceramics and glass. Stable when mixed with copper.
Reacts with bases such as carbonates, oxides and
hydroxides of alkali metals.
642
A basic solution which is highly compatible with
most ceramic and metal powders. Good wettability
and tack, and excellent acid resistance after
curing. Extremely moisture resistant after a high
temperature cure. Sets up in thick cross-sections
when properly formulated.
643-1
A basic solution compatible with most ceramic and
metal powders. Excellent binder for producing high
temperature protective coatings and refractory and
chemically resistant adhesives and patching materials.
Fully cures at low temperatures and sets up in thick
cross-sections when properly formulated.
643-2
Similar to 643-1. Excellent for formulating thin coatings
that set at room temperature and can be raised rapidly
to high temperatures.
644-A
An acidic, colloidal alumina binder developed for
mixing with sized refractory flours and grains to
produce high temperature refractory coatings for
ceramic fiber boards. Used as a superior standalone
system to rigidize refractory fiber shapes.

TYPICAL PRODUCT SPECIFICATIONS
644-S
A colloidal silica aqueous solution which produces high
adhesive strength. Ideal for blending with all types of
granular and fibrous ceramics. Excellent resistance to
temperature, moisture and mechanical shock.
830
A basic solution compatible with most oxide and metal
powders. Ideal for formulating high pigment-to-binder
ratios to produce dense adhesives and coatings. Sets
at room temperature to a moisture resistant film and
does not require a heat cure. Use only for thin coating
systems less than 1 mil thick.
875
An acidic powdered binder system used to formulate
high strength, hydraulic-setting cements for electrical
potting or molding applications. A powder blend is
typically formulated by adding one part binder to four
parts filler by weight. Water is then added in a ratio of
15–20 parts to 100 parts powder blend by weight.
880
High temperature, water-dispersible silicone resin for
producing corrosion and moisture resistant coatings
and sealing porous ceramics.
Aremco’s Ceramabind™ materials are unique
inorganic, water-based binder systems used in the
formulation of specialty adhesives, coatings, sealants
and putties for applications to 3200 ºF. The versatility
of Aremco’s Ceramabind™ products enables users
to blend formulations using most ceramic, glass and
metal-oxide powders. Specific properties such as
coefficient of thermal expansion, thermal conductivity,
dielectric strength, and chemical and moisture
resistance can be optimized.
