Adhesive cures very quickly at room temperature
Master Bond has developed an exceptionally fast curing two component epoxy adhesive for general purpose bonding and develops high bond strength exceeding 140kg/cm2 at room temperature.
Epoxy 'Super Glue' offers 3 minute set
A two component epoxy adhesive sets in 3 min for high performance general purpose bonding and cures in a few hours at ambient temperatures to develop a high bonding shear strength.
The service temperature range is exceptionally wide, starting at -50 deg C and reaching to over 205 deg C (-60 deg F to more than 400 deg F).
EP30HT has a moderate viscosity and is well suited for potting and casting especially recommended where medium viscosity is required for ease of application.
The bonded assemblies exhibit superior dimensional stability and shrinkage after cure is an exceptionally low -0.0003in/in.
Master Bond Polymer Adhesive EP30HT produces high strength, rigid bonds which are remarkably resistant to chemicals including water, oil and most organic solvents.
Adhesion to both similar and dissimilar materials including metals, glass, ceramics, wood, vulcanized rubbers and many plastics is excellent, with shear bond strengths over 3200 lb/in2 being attained.
The hardened adhesive is a superb electrical insulator with a volume resistivity greater than 1015 ohm.cm, a dielectric strength of 440V/mil and a dielectric constant of 3.46 at 1MHz.
Easily applied by brushing or dipping, EP30HT is especially recommended as a conformal coating of electronic components, for bonding fibers to connectors and for glass fiber potting.
It can be used by the micro-electronic, electrical, optical, fiber optic, medical, photonic and chemical industries.
EP30HT also Conforms Title 21, US Code of Federal Regulations, FDA Chapter 1, Section 175.105 and 175.300 for food applications.
It is available in premixed bi-packs and cartridge/gun packaging for convenient dispensing as well as in pint, quart, gallon and 5 gallon container kits. Request a free brochure from Master Bond ...
