Using This Catalog<br />

For most of the chemicals listed in this catalog we provide hazard, handling, and storage codes as well as technical data. The information<br />

provided is believed to be current at time of printing, but is provided without warranty of any kind. We do not warrant that chemicals<br />

listed without codes are necessarily hazard free or that all codes are listed for each chemical.<br />

A typical catalog entry can be read as follows:<br />
