Acrylic and styrene-acrylic water-based paint binders Agett Yuva A: properties, applications, comparison, storage, production, TDS.
Acrylic and styrene-acrylic dispersions Agett A are aqueous polymer systems that are widely used in industry as binders. They form the basis of many modern materials — from paints to adhesives and construction compounds.
An acrylic dispersion is an aqueous emulsion of polymer particles based on esters of acrylic and methacrylic acids. It contains no toxic solvents: everything is based on water and emulsifiers, which is why such materials are considered environmentally friendly and safe for use indoors.
Styrene‑acrylic dispersion is obtained by copolymerizing styrene with acrylic monomers. Thanks to styrene, the material becomes cheaper, and its properties become more balanced: it gains increased strength and water resistance, but at the same time, its UV resistance is partially reduced.
Key properties
These dispersions have a number of important technical parameters that determine their application: – — Glass transition temperature (Tg). It shows at what temperature the polymer transitions from a rigid state to an elastic one.
For acrylic dispersions, Tg can be in the range [−31…+50 °C]; for styrene‑acrylic dispersions, it can be in the range {-10…+50 °C}. This allows you to select the composition for specific tasks: for example, for elastic waterproofing, dispersions with a low Tg are used, and for solid protective coatings — those with a high Tg.
– Minimum film‑forming temperature (MFFT). This is the minimum temperature at which the dispersion particles merge into a continuous film. For most brands, it is 0–22 °C; if necessary, it can be reduced using special additives (coalescents).
– Particle size: 80 to 200 nm. Small particles penetrate pores better, so they are used in deep‑penetration primers. The solid content varies within the range of [40…57%], which affects the consumption and coating thickness.
Application of Agett Yuva A dispersions
Due to their high elasticity, transparency, and UV resistance, acrylic dispersions are used in applications where durability and appearance are important.
– Facade and interior paints. Acrylic formulations do not yellow over time, adhere well to various surfaces, and allow steam to pass through without accumulating moisture in the walls.
– Primers and impregnations. Small particles penetrate deeply into porous substrates (concrete, plaster, wood), improving the adhesion of subsequent layers.
– Adhesives and sealants. Elasticity and good adhesion make them suitable for bonding dissimilar materials and sealing joints that may deform.
– Textile and paper industry. Dispersions serve as binders for fibers, impart water‑repellent properties to fabrics, and fix dyes.
Application of styrene‑acrylic dispersions
Adding styrene makes the material stronger and cheaper, but slightly less resistant to prolonged exposure to sunlight. Therefore, styrene‑acrylic dispersions are more commonly used in applications where a balance between price and performance properties is important:
– Interior paints and enamels. They are cheaper than fully acrylic paints, yet they are quite resistant to washing and household loads.
– Facade coatings for temperate climates. The durable film provides good protection against rain and wind, but in bright sunlight it may slightly change colour over time.
– Construction mixtures and putties. Increased hardness and water resistance make such dispersions a good choice for leveling compounds and repair mixtures.
– Adhesive systems for construction tasks. For example, adhesives for tiles, wallpaper, and sheet materials, where reliable adhesion and moderate elasticity are required.
– Industrial coatings and impregnations. Including for the treatment of non‑woven materials, filters, and technical fabrics.
Comparison and selection
The choice between acrylic and styrene‑acrylic dispersion depends on the requirements for the final product:
– If weather resistance, UV stability, and color retention are more important (for example, for facades in sunny regions), acrylic dispersions of the A‑400, A‑490 versions are better suited.
– If strength, water resistance, and cost are more important (for example, for interior paints, putties, adhesives), styrene‑acrylic dispersions are often chosen.
– For elastic coatings (waterproofing, sealants), dispersions with a low glass transition temperature are selected.
– For solid protective layers (varnishes, wear‑resistant coatings) — with a high glass transition temperature.
Storage and packaging:
Cubes of 1000 and 1050 kg, and barrels of 170 kg.
Storage in covered warehouses at a temperature range of [+5…+35 °C]*
*- at temperatures below +5 °C, coagulation (separation) is possible, after which the material loses its working properties.
*- Compliance with the specified conditions allows you to extend the shelf life to 18-24 months.
Production: China, Turkey. Due to the wide variety of requirements for product properties in different applications, the range of dispersions supplied by Agett is quite extensive; below are the most in‑demand brands; you can obtain the full catalogue and recommendations by contacting us.
