Recently, China AAB Group, a leading global chemical supplier, has launched new products: Aldehyde Resin A-81NB. This resin specially designed for the formula of nail polish, with benzene free as its core safety commitment, is committed to providing safer, high-performance and shiny solutions for the nail industry to meet consumers' dual pursuit of health and beauty.   Aldehyde resin A-81NB is a modified Aldehyde Resin launched by China AAB Group. It aims at the limitations of traditional nail polish resins (such as nitrocellulose) in gloss, drying speed, flexibility and pigment dispersion, and makes breakthrough optimization.   The most significant advantage is that it completely does not contain substances such as benzene, toluene, xylene, etc., which meets the increasingly stringent global cosmetic safety regulations (such as the EU Cosmetic Regulation (EC) No 1223/2009, China's "Technical Specification for Cosmetic Safety", etc.), providing formula designers and factories with peace of mind.   Features and advantages Excellent safety: l Benzene-free: Completely avoid the health risks brought by benzene solvents, and the formula is safer. l Low odor: Helps to reduce the overall odor of nail polish and enhance the user experience. l Compliance with regulations: Meet the safety requirements of the global mainstream market for cosmetic raw materials. Top gloss and transparency: l Give nail polish a mirror-like high gloss and excellent transparency, making the color more vivid, full and deep. l Significantly improve the texture and luxury of nail polish after film formation. Quick drying: l Excellent solvent release, promotes rapid surface drying of nail polish, shortens waiting time, and reduces the risk of scratching. Excellent film-forming and flexibility: l The formed paint film is hard and wear-resistant, while maintaining a certain degree of flexibility, not easy to crack or peel off, and lasting and bright. Excellent pigment wetting and dispersibility: l It can effectively wet and disperse various pigments and effect particles (such as pearl powder, sequins), ensure uniform and stable color, avoid precipitation, and improve the storage stability and use effect of the product. Wide compatibility: l It has good compatibility with commonly used solvents in nail polish systems (such as ethyl acetate, butyl acetate, ethanol), plasticizers (such as phthalate substitutes), nitrocellulose and other resins, and has high formulation flexibility.   Application Areas Aldehyde Resin A-81NB is an ideal choice for improving the performance of various nail polishes: l Top gloss/top coat: Provides high gloss, high hardness, quick drying and protection. l Colored nail polish: Enhances color saturation, gloss, fluidity and uniformity, and improves the application experience. l Base coat: Improves adhesion and smoothness (depending on the specific formula design). l Special effect nail polish: Such as pearlescent, metallic, and sequined nail polish, providing excellent dispersion and gloss carrying capacity. Why choose our Aldehyde Resin A-81NB? With consumers' increasing health awareness and increasingly stringent regulations, Aldehyde Resin A-81NB provides key solutions for nail polish manufacturers: l Safety upgrade: Benzene-free formula responds to the market's strong demand for safer products. l Excellent performance: Significantly improves the gloss, drying speed, durability and color expression of nail polish. l Formulation-friendly: Good compatibility and dispersibility simplify the formulation development process. l Compliance guarantee: Meet the regulatory requirements of major global markets and reduce market access risks.   About China AAB Group China AAB Group is a global company focusing on the research, development, production and sales of high-performance specialty chemicals.

Coating additives are an important component of coating formulations. Although their dosage is usually small (0.1%~5%), they have a significant impact on the storage stability, application performance, film-forming effect, and final film properties of coatings.The selection principle of additives for coatings: high efficiency, minimal negative impact, high cost-effectiveness, and compliance with environmental requirements.The following is the selection method and key considerations for coating additives.     1. Main categories and functions of coating additives Classification Function Example Dispersant Improve pigment dispersibility, prevent sedimentation and flocculation Polyacrylate and Phosphate Esters Wetting Agent Reduce surface tension and improve substrate wettability Organic Silicon and Alkynediol Defoamer Restrain the production of foam and reduce coating defects Mineral Oils; Organic Silicon Leveling Agent Improve coating leveling and reduce orange peel and brush marks Acrylic Ester and Organosilicon Thickener Adjust the viscosity of the coating to prevent sagging and settling Cellulose Ether, Polyurethane, Bentonite Anti-Settling Agent Prevent pigment settling and improve storage stability Gas Phase Silica, Polyamide Wax Cure Accelerator Accelerate coating curing and improve reaction efficiency Organic Tin, Amine Cure Accelerator Prevent UV degradation and improve weather resistance UV Absorbers, Hals Fungicide Inhibit mold growth and extend coating life Isothiazolinones, Benzimidazoles Adhesion Promoter Improve the adhesion between the coating and the substrate Silane coupling agent, epoxy phosphate ester   2. Key factors in additive selection (1) Coating system (water-based/solvent-based/UV curing) l Water-based coatings: water-soluble or water-dispersible additives (such as BYK-190 dispersant, Tego Wet 270 wetting agent) must be selected. l Solvent-based coatings: oil-soluble additives (such as BYK-161 leveling agent, BYK-011 defoamer) must be selected. l UV curing coatings: photoinitiator-compatible additives (such as Tego Rad 2100 leveling agent) must be selected. (2) Coating type (primer/topcoat/clear coat/colored paint) l Primer: Focus on adhesion promoters and rust inhibitors (such as zinc phosphate). l Topcoat: Key considerations include leveling agents, matting agents (such as silica matting powder), and weather resistant additives. l Color paint: water-based paint dispersant, anti settling agent. (3) Construction method (spray coating/brush coating/roller coating) l Spray coating: Low foaming additives and leveling agents are required. l Brush coating/roller coating: anti sagging agents and anti splash agents are required.   3.Environmental and performance requirements Demand Recommended Additives Weatherability Uv Absorbent+Hals High Gloss Leveling Agent+Defoamer Matte/Frosted Matte Powder+Anti Settling Agent Anti-Bacteria   Mold Inhibitor+Algae Inhibitor High Adhesion Epoxy Phosphate Ester+Silane Coupling Agent   4.Verify long-term stability Perform accelerated aging testing (such as storing at 40 degrees for 30 days) to observe whether: l Settlement (adjust anti settling agent) l Viscosity change (adjusting thickener) l Decreased defoaming performance (hydrolysis of defoamers)   5.Common problems and solutions Common Problem Possibility Analysis Solution Ideas Shrinkage Of Coating Film Incompatible Leveling Or Defoaming Agents Replace With Compatible Additives Pigment Sedimentation Insufficient Dispersant/Anti Settling Agent Add Anti Settling Agent Poor Leveling Performance Improper Selection Of Leveling Agent Switching To Organic Silicon Leveling Agent Too Much Foam Wetting Agents Have Strong Foaming Properties Adjust Defoamer Poor Adhesion Insufficient Wetting Of The Substrate Add Adhesion Agent   6.General selection ideas   The material determines the performance, and the reasonable selection of additives can significantly improve the application defects of coatings. It is recommended to optimize the formula through small-scale experiments and pay attention to the synergistic effect between additives. Only by applying them correctly can they be fully utilized.   China AAB Industry Technology Group offers a comprehensive portfolio of additives and polymers, as well as detailed one-to-one customer service to meet specific needs.
