Abstract
Rhamnolipids and/or sophorolipids can be used for increasing coverage and/or for maintaining application properties in the course of storage of coating compositions.
Claims18
A method of increasing coverage of a coating composition, the method comprising:
- mixing at least one rhamnolipid (RL) into a coating composition,
- wherein the at least one rhamnolipid (RL) comprises a mixed composition of di-rhamnolipids (diRL) and mono-rhamnolipids (monoRL),
- wherein the at least one rhamnolipid is a mixed composition with >90% diRL, and
- wherein the coverage is increased compared to a coating composition without the at least one rhamnolipid (RL).
A method of increasing coverage of a coating composition, the method comprising mixing at least one rhamnolipid (RL) into a coating composition, wherein the at least one rhamnolipid is a mixed composition with >90% di-rhamnolipids (diRL), wherein the coverage is increased and, optionally, application properties are maintained, compared to a coating composition without the at least one rhamnolipid (RL), and wherein the at least one rhamnolipid is present within a range from 0.1% by weight to 5.0% by weight, based on the coating composition.
