Abstract
A release agent for rolls, particularly rolls in paper making such as press rolls is described which comprises one or more release active components and optionally conventional additives and which is in the form of a microemulsion. Suitable compositions include those which are essentially free from water and to which water is only added before actual application. The microemulsion or the microemulsion, which upon water dilution is at least intermediately formed, is unstable upon dilution with water to the application concentration which results in a good and homogeneous application of the active ingredients to the press surface. In this way the efficiency of the release agent and the release properties of the rolls are improved. Further, less deposits are formed on the roll surface.
Claims
1. A release agent for press rolls in papermaking systems comprising one or more release active components characterized in that said release agent is in the form of a microemulsion.
2. A release agent for press rolls in papermaking systems comprising one or more release active components characterized in that upon addition of an appropriate amount of water to said release agent a microemulsion is formed.
3. The release agent as claimed in claim 1 characterized in that said release active components are selected from the group consisting of oils, water insoluble surfactants, water insoluble polymers, waxes, and mixtures thereof.
4. The release agent as claimed in claim 1 further comprising a deposit preventing component.
5. The release agent as claimed in claim 5 characterized in that said deposit preventing component is a water soluble polymer.
