The hollow glass microspheres are a low density additive to improve the performance of the resins, they are used to reduce the density of thermosetting type resins, thereby reducing the weight of the final product for which these resins are used.
Q-CEL ® 7019 is a white powder. Its density is 0.11 gr/cc. and a maximum working pressure of 500 psi. The average size of the particles is 80 microns.
The microspheres are also used for the production of filling paste.
