Coalescent
Formula:
C₁₂H₂₄O₃
GOST/CAS:
CAS 25265-77-4
Coalescent is a highly efficient, low-volatile organic solvent-plasticizer that serves as a key component in the production of water-borne coatings. The product temporarily plasticizes the polymer dispersion particles, lowering the minimum film-forming temperature (MFFT) and ensuring the formation of a durable, homogeneous, and long-lasting protective film, even under adverse weather conditions.
Applications
Paint and Coatings Production: Acts as a core technological additive in the formulation of water-borne interior and exterior architectural paints, domestic coatings, and industrial enamels based on acrylic, styrenated acrylic, and PVA copolymers.
Protective and Decorative Coatings: Used in formulations of high-gloss varnishes, wood stains and impregnations, deep-penetrating primers, and elastic exterior textured plasters.
Industrial Adhesives and Glues: Incorporated into water-based adhesive dispersions to improve substrate wetting, optimize setting time, and enhance bond strength.
Construction Chemistry: Utilized in the production of polymer sealants, mastics, and waterproofing compounds to upgrade their physical and mechanical properties.
Key Advantages
Optimal Film Formation: Lowers the MFFT of polymer systems to technically required levels, preventing coating cracking when applied in low-temperature environments.
Enhanced Mechanical Properties: Increases the resistance of the cured paint film to wet scrubbing, UV radiation, weathering, and mechanical stress.
High Stability and Compatibility: Demonstrates excellent hydrolytic stability, distributes evenly throughout the dispersion without causing polymer coagulation, and maintains the viscosity profile of the coating during storage.
Aesthetic Excellence: Promotes superior paint leveling and flow, enhances the gloss of topcoats, and prevents sagging, pinholes, or cratering during application.
Storage & Transportation
- Store in dry, cool, covered warehouses in tightly closed original packaging, away from heat sources, open flames, and strong oxidizing agents.
