Electrically Resistant Adhesives for Special Application

Duralco NM25  Magnet Bonding Adhesive 

Duralco NM25 is a adhesive proven for bonding magnets while withstanding the high temperatures encountered in high performance applications.
It is free of magnetic particles or conductive fillers which would interfere with magnetic fields while in use.Just mix and apply.
NM25 cures at room temperature to provide excellent chemical, solvent and moisture resistance. Will form thin bond lines and is ideal for use in applications with minimum clearance. 

NM25 has a medium viscosity and can form thin bond lines.
NM25 HV is a non-sag, putty.
NM25 HT can be used up to 600ºF after a moderate heat cure.

Duralco 4400 : 400ºF

Transmits Heat - Electrically Resistant

Use Duralco 4400 for high strength, thermally conductive and electrically resistant bonds.Cures at room temperature without any objectionable odors.
Duralco 4400 provides the thermal shock resistance and flexibility required to accommodate differences in thermal expansion which occurs during high heat flows.
Users Report:
A "glass feed thru" was bonded to a brass housing and
repeatedly cycled from liquid Nitrogen temperatures to 250ºF, while maintaining its vacuum integrity.
Duralco 4400's unique combination of bond strength, flexibility and thermal conductivity proved to be successful in this severe environment.
Note  A4400 This adhesive can be stiffened at the bottom of the opening, and you can heated to 55~60ºC, It will be diluted again.

Material selection is reponsible with user's  own decision.

Nylon bonder - Sterilizable - Low expansion - Superbonder

BOND-IT 7050
Super Nylon Bonder

Bond-IT 7050 is an activated epoxy that incorporates adhesion promoters right into the epoxy's backbone structure permanently improving the epoxy's adhesion and bond strength.

Adheres to most plastic surfaces producing bonds that are, in many cases, stronger than the plastic substrates themselves.

Bonds combinations of dissimilar materials including metals, ceramics, plastics, glass, etc, and cures at room temperature.



Resbond S5H13 - Hot Sterilizable

Resbond S5H13 is a unique epoxy to bond and insulate stainless steel, metals, glass and ceramic components to assemble to use upto 500ºF. after cure at that  room temperature. It is specially formulated for various medical applications. It is resist the severe conditions of repeated hot sterilization and resistant to most common chemicals and solvents.

Users Report:
It seals Bi-Polar, Electro-Cauterizers and withstands thousands of successful sterilization cycles at 200°c.
S5H13 is commonly used for high performance bonding, assembling, potting, sealing, coatings and repairs in instruments, devices, equipment, etc.


Duralco 4463

Duralco 4463 is a low expansion adhesive and potting compound. It is good to use 260°c
