Soytex Extender LZR is used in the manufacture of soy oil-based business forms inks that need to be compatible with laser printers. Soytex Extender LZR is a high soy oil content product (35%), plus it contains 20 percent tung oil for extra hard dryback. Soytex Extender LZR is also 100 percent solids. It is also used as a transparent white extender for making tints. 

​

Soytex Extender LZR is very drier-reactive, making it an ideal vehicle from which to make ultra fast-drying laser inks. 1% of cobalt drier (based on 6% metal content) would be adequate for making air-drying inks that could be printed in less than 72 hours. As with all Kerley laser-compatible products, printers must be advised that printed material must be left to air dry with adequate windage (air exchange). Shrink wrapping of printed material is strongly discouraged. Use of non-absorbent stocks will also cause product performance problems. A minimum of 72 hours drying time is suggested before printing with laser printers will occur.
