A sealing glass modifier that decreases the chemical reduction of PbO in a PbO-containing sealing glass to metallic lead during sealing or firing, and enables the sealing glass to be used in combination with a VOC-free or low-VOC vehicle.

The modifier may also be a waxy substance which cannot be crushed, a viscosity modifier, a dye or a taste modifier.

The binder includes a viscosity modifier and a surface tension modifier.

Glass beads of the invention comprise greater than 80 weight percent silica, active rare earth dopant, and modifying dopant.

In one embodiment the different modifier is a more favorable modifier.

A mixture including a universal resin, a curing agent, a flow modifier, and a colorant is applied to the glass waste.

A sealing glass modifier that decreases the chemical reduction of PbO in a PbO-containing sealing glass to metallic lead during sealing or firing, and enables the sealing glass to be used in combination with a VOC-free or low-VOC vehicle.

The plar binder includes a viscosity modifier and a surface tension modifier.

At least one surface-modifying group is a polymeric silane surface modifying group.

At least one surface-modifying group is a non-polymeric silane surface modifying group.

Alternatively, the modifier may be dissolved or dispersed in the vehicle.

Hydrophilic polymer is modified with a gaseous modifier or a powdered modifier made from a liquid modifier.

The compositions can include a polymer, a polyacrylate rheology modifier, and a polyurethane rheology modifier.

The modifier may be incorporated as a component of the sealing glass.
