FOR IMMEDIATE RELEASE

                   KRONOS WORLDWIDE, INC. ANNOUNCES CLOSING OF
                              PRIVATE PLACEMENT OF
                     SENIOR SECURED NOTES BY ITS SUBSIDIARY
                           KRONOS INTERNATIONAL, INC.



DALLAS, TX -April 11, 2006 - Kronos Worldwide,  Inc. (NYSE: KRO) today announced
the  closing  of a private  placement  by its  wholly-owned  subsidiary,  Kronos
International,  Inc., of (euro)400  million  ($480  million at current  exchange
rates) of Senior Secured Notes due 2013 at an interest rate of 6 1/2% and priced
at 99.306%.  Kronos  International,  Inc. conducts Kronos  Worldwide's  titanium
dioxide  pigments  operations  in Europe.  The net  proceeds of the  offering of
approximately  $467.9 million,  together with approximately $2.1 million of cash
on hand,  were  used to repay  Kronos  International's  outstanding  8?%  senior
secured notes due 2009.

The Notes were sold to qualified  institutional  buyers in the United  States in
reliance on Rule 144A and to persons outside of the United States in reliance on
Regulation S under the  Securities  Act of 1933, as amended.  The Notes were not
registered  under  the  Securities  Act and,  unless so  registered,  may not be
offered or sold in the United States except pursuant to an exemption from, or in
a transaction  not subject to, the  registration  requirements of the Securities
Act  and  applicable  state  securities  laws.  This  press  release  shall  not
constitute  an offer to sell or the  solicitation  of an offer to buy, nor shall
there be any sale of the Notes in any state in which such offer, solicitation or
sale would be unlawful  prior to the  registration  or  qualification  under the
securities laws of any such state.

The statements in this release relating to matters that are not historical facts
are  forward-looking   statements  that  represent   management's   beliefs  and
assumptions based on currently available information. Forward-looking statements
can be identified by the use of words such as "will," "anticipates,"  "expects,"
or comparable  terminology or by discussions of strategy or trends.  Although we
believe that the expectations  reflected in such forward-looking  statements are
reasonable,  it cannot give any assurances that these expectations will prove to
be correct.  Such  statements by their nature  involve risks and  uncertainties,
including,  but not  limited  to,  global  economic  and  political  conditions,
financial  market  conditions,  changes  in  foreign  currency  exchange  rates,
operating interruptions  (including,  but not limited to, labor disputes, leaks,
fires, explosions,  unscheduled downtime,  transportation interruptions, war and
terrorist  activities),  and  other  risks  and  uncertainties  detailed  in our
Securities and Exchange  Commission  filings.  Should one or more of these risks
materialize (or the  consequences of such a development  worsen),  or should the
underlying  assumptions prove incorrect,  actual results could differ materially
from those  forecasted  or expected.  We disclaim any intention or obligation to
update  publicly  or  revise  such  statements,  whether  as  a  result  of  new
information, future events or otherwise.

Kronos  Worldwide,  Inc. is a major  international  producer of titanium dioxide
