What is the use of rosin ester?

What is the practical application of rosin ester? The compound has its origin in Germany in the late 19th century. Rosin ester tackifier was initially used for the paper coating to create a raised print on fabric, later used for laminating plastic and rubber materials.

Pressure-sensitive adhesive

The invention relates to the rosin ester helpful tackifier in the making of pressure-sensitive adhesive. The simplest rosin ester mixtures are made by dissolving a rosin oil, which can be proportionated into one or more fatty acids, including pentaerythritol and glycerol. A less diluted version of this mixture can also be prepared using one or two ethyl esters, propylene glycol (which acts as a solvent), or a combination of several fatty acids and one or more aromatic hydrocarbons.

Emulsion bonding agent

This type of emulsion bonding agent is used to create foam and can be used as a penetration additive for hard metals, plastics, leather, and some synthetic fabrics. The foam made by this tackifier is called ‘rosin,’ and it is usually less dense than the lubricating oil. The use of this ingredient increases the tackiness of the product due to the increase in viscosity. The term softening point is a product characteristic directly influenced by the oil component and not by the fatty acid methyl esters. The duration of softening point is mainly dependent on the viscosity of the final foam creation and the type of foam produced.

An embodiment of an ester tackifier

Another embodiment of an ester tackifier is present in an ultraviolet curing fluid. In the ultraviolet curing process, the UV curing fluid is infused into the medium, such as the leather, which must first be cleaned and softened. Then, the UV curing fluid is passed on to the leather, which must be exposed to the curing process for some time, such that the leather absorbs the curing fluid. The amount of absorption varies with the type and brand of leather.

Viscosity range

In another embodiment, a particular viscosity range is infused onto a flat plate. In the process of heating, the plate becomes warm enough to absorb a given viscosity range. In yet another embodiment, the heat sink of the machine is configured in such a way as to have one or more of the heat sinks mounted on different sides of the heat exchanger/sink unit. This arrangement allows for flexibility in mounting heat sinks and heat exchangers in various configurations without any significant change in the overall efficiency of the equipment.

Softening point

A softening point is infused onto the plate through mechanical infusion in another embodiment of a rosin-based tackifier component. The softening point is measured using a solute, where the higher the index, the more complex the plate will be to work with. The plate will be placed in a configuration to work with the most commonly available hard plate materials while maintaining the softening point.

Formulation of the water-soluble

One embodiment uses a formulation of the water-soluble, water-dispersible adducted rosin ester as a moisture-sensitive adhesive. The water-insoluble, water-dispersible adducted rosin ester is used in a spray bottle component in the second embodiment. In the third embodiment, the water-insoluble, water-dispersible adducted rosin ester is used as an emulsifying ointment in a thin-film ointment. The fourth embodiment uses the water-insoluble, water-dispersible adducted rosin ester as a topical antifungal cream. The water-insoluble, water-dispersible adducted rosin ester is also described in one embodiment as a sunscreen in which sunscreen (including a sunblock that includes the water-insoluble, water-dispersible adducted rosin ester) is applied to a skin exposed to ultraviolet radiation from the sun. A sunscreen that contains the water-insoluble, water-dispersible adducted rosin ester is described in another embodiment.

Conclusion

A sunscreen in which the water-soluble, water-dispersible adducted rosin ester is mixed with sunscreens (including a sunblock that includes the water-insoluble, water-dispersible adducted rosin ester) is described in another embodiment. Other examples include emulsifiers, surfactants, and buffer systems. In some cases, the sunscreen in use is applied to the surface or the interior of a material that is to be protected. For example, sunscreen can be applied to protect the hair and skin or may be used to prevent the penetration of moisture into the skin.
