Low viscosity potting compound is flexible
A new flexible, tough epoxy potting and encapsulation compound has extraordinarily low viscosity and is easy to apply.
It can be used in thick and thin cross sections.
Upon exposure to an ultra violet (UV) light source, the UV22 cures rapidly at room temperature and is not oxygen inhibited.
It has a service operating temperature range of -50 deg C to150 deg C .Post curing the UV22 material enhances its temperature resistance profile, said Master Bond.
Adding heat (90-125 deg C for 30 min) will give it a glass transition temperature of 135 deg C.
Master Bond told manufacturingtalk.com that it is far higher than traditional UV systems.
The post curing is also effective in increasing its chemical resistance to solvents, acids and bases.
* UV22 is easy to use - despite the relatively high percentage of nanoparticles (>35%) added to the UV22, it still retains high transparency and low viscosity without sedimentation due to the agglomerate-free colloidal dispersion of the nanoparticles in the resin.
UV22 has a Shore D hardness of >80 and a tensile strength of >4,600 lb/in2.
It has a refractive index of 1.52 and shrinkage of 1-2%.
Its electrical insulation properties are superior, said Master Bond.
UV22 is 100% reactive and contains no solvents or diluents.
It is available for use in pint, quart, gallon and 5 gallon containers.
It is also available in syringe applicators.
Higher viscosity versions are also available.
