otronics’ Unique Catalytically Cured Duralco 4525 Low

Shrinkage System, provides the highest temperature prop-
erties to be obtained with a simple room temperature cure.

Duralco 4525 provides excellent adhesion and electrical

properties and has the lowest moisture absorption required for
many critical electronic applications.

Duralco 4525 contains no solvents or volatiles. It is machin-

able and resistant to corrosion, radiation, all common chemicals
and solvents.

No more complicated, costly and time consuming heat cures.

Just apply and cure at room temperature.

Extensively tested and used in hydrochloric, phosphoric, sul-

furic, and nitric acids, as well as in caustic and chromic oxide
solutions for use in the chemical processing industries.

4525 is being used for high performance bonding, potting,

sealing, coatings, repairs, castings and jigs. It is found in appli-
ances, instrumentation, motors, equipment, etc.
