The differences between the three types of emulsions Did you know? The durability, environmental friendliness, and lifespan of stone-effect paint all depend on the "emulsion" it contains! What are the differences between the three common emulsions on the market: styrene-acrylic, pure acrylic, and silicone-acrylic? Afraid of choosing a cheap one that won't last, or a expensive one that's a waste of money? Today, we'll explain the differences to help you avoid common mistakes and choose the right high-quality emulsion! Styrene-acrylic emulsion: Cheap but with "obvious shortcomings," choose with caution Styrene-acrylic emulsion Styrene-acrylic emulsion is the cheapest of the three emulsions and was a common raw material for early stone-effect paints, but its disadvantages are very prominent, and it has gradually been phased out of mainstream household applications. Core characteristics: Contains benzene compounds, posing a potential toxicity risk, and has poor environmental performance; Performance: Extremely poor weather resistance and yellowing resistance; easily yellows and fades when exposed to the outdoors for a long time; "whitening" occurs when exposed to water, affecting the appearance; the paint film lacks toughness and is prone to cracking and peeling later, especially in areas with large temperature differences or high humidity; Service Life: Only 3-5 years; while seemingly saving money initially, the subsequent repair and renovation costs are higher; Applicable scenarios: Not recommended for home use! Only suitable for temporary buildings, low-budget commercial projects, and other scenarios with very low requirements for environmental protection and durability. Pure acrylic emulsion:The preferred choice for home use, safe, durable, and cost-effective! Pure acrylic emulsion Pure acrylic emulsion is currently the mainstream choice for household exterior stone-effect paint, balancing environmental friendliness and practicality, offering excellent value for money. Core Features: Non-toxic and harmless, environmentally compliant, and will not cause pollution to the human body or the environment; the paint film has high elasticity, can adapt well to minor deformations of the wall, forming an integral part with the wall structure, and has strong adhesion; Performance: Excellent resistance to acids and alkalis, aging, and frost, able to withstand harsh weather conditions such as wind, sun, rain, and snow, and is not prone to yellowing or chalking; excellent water resistance, and will not turn white when exposed to water; Service Life: Approximately 15 years, requiring no frequent maintenance under normal use, resulting in low long-term maintenance costs; Applicable Scenarios: Most household scenarios in general residential buildings (including self-built houses and exterior wall renovations of commercial buildings). Silicone Acrylic Emulsion: High-end, top-of-the-line performance with an ultra-long lifespan! Silicone acrylic emulsion is based on...

The main differences between the milky white and translucent states of water-based polyurethane resins are as follows: Microscopic Structure • Different particle size: The average particle size of polyurethane particles in milky white water-based polyurethane resin is greater than 0.1 μm; the particle size of translucent water-based polyurethane resin is between 0.001 and 0.1 μm. • Different molecular aggregation states: The molecular aggregation state of milky white resin may be relatively loose, with a relatively disordered arrangement of molecules and many scattering centers; the molecular aggregation state of translucent resin is relatively regular, with more ordered intermolecular interactions and arrangements, and relatively fewer scattering centers. Macroscopic Properties • Differences in optical properties: Due to the larger particle size, milky white water-based polyurethane resin has a strong light scattering effect, resulting in an opaque milky white appearance; the smaller particle size of translucent resin results in weaker light scattering, allowing some light to pass through, thus appearing translucent. • Differences in film formation: Generally, milky white water-based polyurethane resin may have a certain degree of haze after film formation, with relatively low transparency, but possibly better hiding power; translucent water-based polyurethane resin has higher transparency after film formation, better showcasing the original color and texture of the coated object. • Different stability: Translucent water-based polyurethane resin has a smaller particle size, larger specific surface area, and higher surface energy, making it more susceptible to external factors during storage and use, potentially leading to aggregation or deterioration; milky white water-based polyurethane resin is relatively more stable. Formulation and Synthesis Process Aspects • Different hydrophilic component content: The more hydrophilic components the resin contains, the finer the particle size of the emulsion, and the more translucent it becomes. Therefore, milky white water-based polyurethane resins have a relatively low content of hydrophilic components, while translucent resins have a relatively high content of hydrophilic components. • Differences in synthesis process: During the synthesis process, process parameters such as stirring speed, temperature, and reaction time affect the particle size and appearance of the resin. Generally, the more vigorous the stirring, the finer the emulsion particles, and the more likely it is to appear translucent.

Three Core Advantages of Polyurethane Topcoat: 1. High Weather Resistance: Superior UV resistance compared to epoxy paints; does not chalk or lose gloss under outdoor exposure, maintaining vibrant colors. 2. Strong Comprehensive Protection: Offers excellent wear resistance, impact resistance, oil resistance, and resistance to mild chemicals, with superior mechanical properties. 3. Easy Application: Can be sprayed or brushed, with good leveling properties and a full paint film; fast drying time (approximately 2 hours), improving construction efficiency. Application Scenarios:Surface protection for outdoor facilities such as bridges, machinery, and steel structure factories; the "standard topcoat" for heavy-duty anti-corrosion systems. Sinograce Chemical produces water-based polyurethane resin used in water-based metal anti-corrosion topcoats.
