Abstract
A low density component, such as hollow microspheres, dispersed in a binder to produces a material having a surface that is comfortable to the touch even after extended exposure to an energy source, such as direct sun light.
Claims10
A method for forming a floor tile comprising:
- mixing a hardener into a base epoxy resin to form a binder;
- blending about 40 weight percent to about 80 weight percent of a low density additive including hollow microspheres having a density of about 0.3 to about 0.5 g/cc into about 20 weight percent to less than about 60 weight percent of the binder to form a slurry;
- pouring the slurry into a mold;
- moving the mold to ensure distribution of the hollow microspheres in the slurry;
- curing the slurry to form the floor tile so that the floor tile has the hollow microspheres dispersed throughout and a portion of the hollow microspheres form a portion of an outer surface of the floor tile;
- and
- wherein the low density additive is effective such that the outer surface of the floor tile has a temperature of about 100° F. or less upon exposure to an energy source.

- curing the slurry to form the tile;
- wherein the low density additive is effective such that a surface of the tile remains about 100° F. or less upon exposure to an energy source;
- and
- wherein the low density additive is a frothing agent to aerate the binder to form a predetermined volume of void space within the tile.
