Introduction to Wax Emulsion Malaysia – What is it?
Wax emulsion is a liquid mixture of wax and water. It is used as a coating for paper and cloth to create a waterproof surface. The wax in the emulsion can be any type of wax, but it is typically made up of natural or synthetic waxes. Non-ionic emulsifiers (steric mechanism) or ionic emulsifiers, most commonly anionic, can stabilise wax emulsions (electrostatic mechanism). The emulsion has the best stability when anionic and non-ionic emulsifiers are combined because wax particles are safeguarded by both stabilisation processes. Each stabilisation mechanism also significantly affects the overall formulation, adding flexibility to the formulation process, in addition to having its own benefits and drawbacks. The emulsion can be applied by dipping the paper or cloth into the liquid or brushing it with a paintbrush. The water in the mixture helps seal the paper or cloth and protects it from wet environments. In this article, we will see where wax emulsion Malaysia is used too.
Aspects To Be Considered If You Want To Create Wax Emulsion Malaysia
1. The Melting Point
When curing is required, it is critical that the wax has a melting point lower than the curing temperature. Therefore, the wax can melt, can transfer to the coating surfaces, recrystallize when the coating gets cool, and form a consistent and continuous film.
2. The Thickness Layer Of the Coating
The highest dried wax density should be at the dried film surface in order to maximize the wax effects. As a result, the particle size of the wax emulsion should be as close as possible to the coating layer thickness. When the concentration is properly adapted, a wax emulsion with a smaller particle size can perform equally well.
3. The Level of Wax Emulsion pH
The pH of the wax emulsion should be within one unit of the system it is added to. Aqueous ammonia or acetic acid can commonly be used to change the pH of the emulsion if necessary.
4. The Surfactant Type
The type of surfactant used can also affect compatibility with other components and overall formulation stability. Stability is improved by matching the emulsion charge to the coating charge.
5. The Component Addition Order
The order in which ingredients are added can be a crucial element in ensuring stability in water-based formulations. The wax emulsion can be added last to minimise agglomeration and maximise overall stability. Before incorporation, the emulsion can be further diluted with soft or demineralized water to lessen the shock.
6. The Regulatory Aspects of Waxes
If the emulsion is intended for use in a coating or package that will come into contact with food, the wax and any other additives that are incorporated (such as emulsifiers, antifoams, biocides, etc.) must comply with all applicable laws and regulations (FDA, BfR, European Directives, Kosher Certification etc.).
The Applications Of Wax Emulsion Malaysia
Among the many uses for wax emulsions are printing inks, leather, paper, and polishes. They enhance products with scratch resistance, corrosion protection, various finishes, and more.
Fruits, vegetables, and candies can all be coated with emulsions made from natural waxes. Emulsions of beeswax, paraffin, and carnauba wax are frequently found in creams and ointments.
