Advantages of Floor Coating Dispersants
Advantages of Floor Coating Dispersants
Floor coating dispersants significantly enhance the overall performance of coatings by optimizing the dispersion of pigments and fillers. Their benefits extend throughout the entire production, construction, application, and environmental protection process. The following analysis focuses on four dimensions: performance improvement, efficiency optimization, environmental safety, and cost-effectiveness:
I. Performance Improvement:Comprehensively Optimizes the Physical and Chemical Properties of Coatings
Enhanced Mechanical Properties of Coatings
Hardness and Abrasion Resistance: Dispersants evenly distribute pigments and fillers, reducing stress concentration within the coating and improving surface hardness. For example, in epoxy floor coatings, evenly dispersed silica fillers form a dense network, improving the coating's abrasion resistance by over 30%.
Impact Resistance: Dispersants reduce the risk of particle agglomeration, preventing cracking due to localized weaknesses in the coating. Experimental results show that floor coatings using dispersants can increase impact strength by 25%, making them suitable for high-traffic areas such as factories and warehouses.
Improved Optical Properties:
Gloss and Transparency: Dispersants control pigment particle size distribution and reduce light scattering. For example, in water-based floor coatings, dispersants reduce the average pigment particle size from 5μm to 2μm, increase 20° gloss from 65% to 85%, and improve light transmittance in clear coatings by 15%.
Color uniformity: Prevents color floating and blooming, ensuring consistent color in multi-colored floors (such as colored sand epoxy). Controlled flocculation dispersants stabilize pigments through hydrogen bonding, eliminating in-can settling and film color variation.
Improved durability:
Weather resistance: Dispersants reduce pigment particle aggregation and degradation under UV exposure, extending the service life of outdoor floors (such as parking lots). For example, coatings containing polyurethane dispersants reduced color difference ΔE by 40% in UV accelerated weathering tests.
Chemical resistance: Evenly dispersed fillers block the penetration of corrosive media. In corrosion-resistant flooring, dispersants achieve a denser distribution of zinc powder fillers, extending salt spray test pass time to over 1000 hours
II. Efficiency optimization: Shorten production cycle time and reduce energy consumption.
Accelerate the grinding process: Dispersants reduce the surface energy of pigments through wetting, reducing grinding time. For example, in the dispersion of inorganic pigments (such as titanium dioxide), the use of dispersants can reduce grinding time from 4 hours to 2.5 hours, improving efficiency by 37.5%.
Polymer dispersants (such as acrylates) form an adsorption layer, preventing particle reaggregation during grinding, further shortening process time.
Increasing Pigment Loading
Dispersants reduce system viscosity, enabling a 10%-20% increase in pigment loading. For example, in thick-build epoxy flooring, pigment loading can be increased from 30% to 35%, reducing coating thickness and the number of application coats while maintaining leveling.
Simplifying the Production Process
Dispersants reduce post-processing steps (such as filtration and viscosity adjustment), reducing operational complexity. For example, paint formulations using self-dispersing pigments can skip the high-speed dispersing step and proceed directly to the paint letdown stage.
III. Environmental Safety: Complying with Green Manufacturing and Health Standards
Reducing V Emissions
Water-based dispersants replace solvent-based additives, reducing volatile organic compound (VOC) emissions. For example, the VOC content in water-based floor coatings can be reduced from 200g/L to below 50g/L, meeting indoor air quality standards.
Reducing the Use of Hazardous Substances
New dispersants (such as bio-based polyesters) do not contain hazardous ingredients such as APEOs (alkylphenol ethoxylates) and heavy metals, minimizing harm to humans and the environment during application and use.
Improving Application Safety
Dispersants optimize the rheological properties of coatings, reducing splash and dust during spraying, and lowering operator exposure risks. For example, low-viscosity systems reduce airless spray pressure by 20%, minimizing rebound and air pollution.
IV. Cost-Effectiveness: Balancing Performance and Economy
Extending Product Shelf Life
Dispersants prevent pigment settling and coarsening, reducing performance degradation during storage. For example, after six months of storage, the viscosity change of a coating containing a polymer dispersant was reduced from 30% to 10%, reducing returns and waste.
Reducing Overall Costs
Raw Material Costs: By improving pigment utilization, excess addition is reduced. For example, dispersants can increase the tinting strength of carbon black by 20% while reducing the amount used by 15%.
Application Cost: Evenly dispersed paint reduces coating thickness and rework. Experiments show that floor coatings using dispersants increase application efficiency by 15% and reduce labor costs by 10%.
Maintenance Cost: Improved durability reduces the need for subsequent repairs. For example, the service life of corrosion-resistant flooring has been extended from 5 years to 8 years, reducing overall lifecycle costs by 37.5%.
V. Application Scenario Adaptability: Meeting Diverse Needs
Industrial Flooring: Highly wear-resistant and chemical-resistant dispersants are suitable for factories and workshops, improving equipment operational stability.
Commercial Flooring: High-gloss, non-slip dispersants are used in shopping malls and hotels, balancing aesthetics and safety.
Outdoor Flooring: Weather-resistant and UV-resistant dispersants are used in parking lots and plazas to extend service life.
Specialty Flooring: Anti-static and conductive dispersants are used in electronics workshops to meet functional requirements.
