Orthosilicate ester containing heat transfer fluids.

摘要

The invention deals with orthosilicate ester-containing heat transfer fluids.
<??>These fluids, when they are under the form of a composition concentrate comprising at least one glycol together with at least one orthosilicate ester, have improved stability at a pH of between about 6.0 and about 8.0.
<??>They are useful in anti-freeze compositions because they do not exhibit gel problems in this pH range.
