Water based dispersion of lead-fee glass frit for high temperature forging of titanium.

BONDERITE® L-FG 153 (known as Deltaglaze 153) is a water based, dispersion of lead-free glass frit recommended for hot forming titanium at high temperatures ( 1600 - 1800°F).  Provides lubrication and protects from gaseious contamination while heating.


Typical application for forging and extrusion of stainless steel and nickel-base alloys. BONDERITE® L-FG 153 is supplied as a concentrate and may be diluted with water or used as is.
