Selection and formula optimization of rheological additives for acrylic sealant sealant filling materials
Waterborne acrylic sealing sealant belongs to a high solid content paste system, with core requirements: stable consistency without opening the tank, smooth extrusion, no sagging during construction, smooth surface after molding, no water stratification during long-term storage, no hardening at l...Read more -
Wetting agents and dispersants, essential differences, mechanism of action, and analysis of composite application technology
Wetting agent and dispersant are two indispensable interface aids in the processing of powder pigments and fillers in water-based coatings, printing ink, building materials slurry and fine chemical lotion systems. The two are often used in combination and have highly synergistic functions, but th...Read more -
Technical specifications for titanium dioxide used in building sealants
The integrity of modern architecture largely depends on the performance of its joints and gaps. Building sealants – whether based on silicone, polyurethane, or silane modified polymers – must build bridges between structural components while withstanding continuous movement, moisture,...Read more -
Titanium dioxide solution suitable for paints and coatings
Covering power is one of the core indicators for measuring the performance of water-based paint, which refers to the ability of the paint film to cover the underlying substrate or the original color, directly affecting the coating effect, construction cost, and product competitiveness. Improving ...Read more -
Complete selection plan for water-based titanium dioxide anti settling dispersant
1、 First, clarify the core logic of titanium dioxide settling and the underlying logic and basis for selecting titanium dioxide dispersants Rutile and anatase titanium dioxide have a density of 4.2g/cm3, while water only has a density of 1g/cm3. The physical density difference is extremely large...Read more -
How can water-based paint improve its coverage effect
Analysis of the Strategy for Enhancing the Covering Power of Waterborne Paint Covering power is one of the core indicators for measuring the performance of water-based paint, which refers to the ability of the paint film to cover the underlying substrate or the original color, directly affecting ...Read more -
Is HEMC suitable for indoor and outdoor buildings
HEMC (Hydroxyethyl Methyl Cellulose) is highly suitable for indoor and outdoor applications in construction. As a non-ionic cellulose ether derived from natural cotton or wood pulp, HEMC provides reliable water retention, improved construction performance, and enhanced adhesion in a wide range of...Read more -
How to use HEC to achieve optimal rheological properties in sealants and fillers
Rheological optimization is a key aspect of formulating sealants and fillers to ensure they function as expected. One of the commonly used rheological modifiers in these formulations is hydroxyethyl cellulose (HEC). HEC is a multifunctional polymer that can be adjusted as needed to achieve specif...Read more -
HEMC and HEC’s product areas, performance differences, and usage scenarios
Complete comparison between HEMC (hydroxyethyl methyl cellulose) and VSHEC (hydroxyethyl cellulose) 1、 The essential difference in chemical structure HEC hydroxyethyl cellulose is a pure hydrophilic structure with only hydroxyethyl (- CH ₂ CH ₂ OH) substitution, no methyl hydrophobic groups, and...Read more -
Traceability of Common Defects of Acrylic lotion Finished Coatings and Optimization Scheme of lotion Replacement
As the core film-forming matrix of waterborne coatings, waterborne acrylic lotion’s monomer ratio, polymerization process, core-shell structure, emulsification system and crosslinking mode directly determine the film-forming performance, weather resistance, storage stability and constructio...Read more -
The antagonistic conflict between wetting agents and defoamers (maximum pit point, mechanism+case+practical solution of coating formula)
As the core film-forming matrix of waterborne coatings, waterborne acrylic lotion’s monomer ratio, polymerization process, core-shell structure, emulsification system and crosslinking mode directly determine the film-forming performance, weather resistance, storage stability and constructio...Read more -
Analysis of Water based Architectural Coating Additives Technology – Wetting, Dispersion, and Controlled Bubble Wetting Principles and Application Practice
1、 Preface Waterborne architectural latex paint is mainly composed of lotion, pigments and fillers, water and various functional additives. Although the amount of additives added is low, it directly determines the production stability, construction performance, and final appearance of the paint ...Read more
