What is an Acrylic Emulsion

  • What is it?
acrylic emulsion - What is an Acrylic Emulsion

Acrylic emulsion in Malaysia is a milky white polymer emulsion, mainly polymerized by acrylic monomers, polymerized by the initiator in the presence of an emulsifier, using water as a solvent and an initiator. The acrylic emulsion has excellent adhesion and waterproof properties and can be used in the textile industry, such as non-woven fabrics, flannel blankets and lamination. Some products can be used in civil engineerings, such as cement mortar, caulking and elastic cement, and other products can be used in coatings, such as water-based paints for interior and exterior walls. 

  • Emulsion

The word “lotion” is derived from Latin, meaning “milk” because milk is technically an emulsion of fat and water. The emulsion is a mixture of two or more liquids that usually cannot be mixed. In an emulsion, a liquid called the dispersed phase is dispersed in another liquid called the continuous phase. These two liquids can form different types of emulsions, such as oil-in-water or water-in-oil. Some examples of easily recognizable emulsions are balsamic vinegar, mayonnaise, and homogenized milk. Emulsions usually have no static structure because they are liquid.

  • Acrylic

This reminds us of acrylic. Acrylic resins are a group of thermoplastic substances derived from acrylic acid, methacrylic acid and other related compounds. More specifically, polymethyl acrylate is an acrylic resin used in textile finishing agents, adhesives, paints and other related products in its emulsified form. Acrylic resins have great advantages when used as paint ingredients. They are usually the main components of latex paint (called “latex paint” in the UK). Compared with vinyl, interior and exterior wall coatings with a higher proportion of acrylic resin have higher water resistance, better anti-fouling protection, better adhesion, stronger resistance to foaming and cracking, and resistance to The ability of alkaline cleaners. Acrylic resin is considered to be extremely waterproof, making it very suitable for electrical appliances and outdoor furniture. Acrylic resin can be used for decades in its solid form and will not turn yellow in the sun.

  • Using PCCS to determine the particle size and relative concentration of the pure acrylic emulsion

The size, distribution and concentration of the particles are important quality characteristics for the best functionality and processability of the emulsions. Fine particles improve pigment binding and film-forming ability. Besides that, acrylic emulsions with fine particles have a larger surface area and therefore have greater interaction with thickeners. The size of the particles also affects the viscosity of the emulsion: large particles generally mean low viscosity, while small particles result in high viscosity. Pure acrylic emulsions are usually in a cloudy, highly concentrated form, and must also be measured in this original state. The possible dilution of the emulsion can cause changes in droplet size, particle formation and stability. The photon cross-correlation spectroscopy (PCCS) implemented in NANOPHOX eliminates possible multiple scattering, so it can be used to measure high concentrations. The measurable particle concentration is much higher than traditional dynamic light scattering (DLS) using photon cross-correlation spectroscopy (PCS).  The graphic arts, as well as industrial coatings sectors, rely heavily on acrylic polymer emulsions and other water-based acrylic polymer products. Gellner Industrial manufactures a variety of specialised resins that can be utilised in a variety of applications in various fields. These resins are made up of a precise blend of water-based polymers, and when employed in water-based coatings and printing inks, they produce great results…
