Product Recommendation | Dimethylol Butyric Acid (DMBA) Dimethylol Butyric Acid (DMBA) CAS No.:10097-02-6 Molecular Formula:C6H12O4 Molecular Weight:148.16 Physicochemical Properties:White crystalline solid Melting Point:108–115 °C;  soluble in water, methanol, acetone, etc. Applications of Dimethylol Butyric Acid (DMBA) Core Function: A hydrophilic chain extender for water-based polyurethanes. Within the polyurethane molecular chain, DMBA plays a dual role: Chain Extender:The two primary hydroxyl groups in its molecule react with isocyanate groups (-NCO), thereby extending the polymer molecular chain. Internal Emulsifier:Once the carboxyl group in the molecule is neutralized by a base (such as triethylamine), it transforms into a carboxylate group. These ionic groups impart excellent hydrophilicity to the polyurethane resin, enabling it to disperse stably in water—forming a water-based polyurethane emulsion—without the need for external emulsifiers or large quantities of organic solvents. DMBA is a neopentyl carboxylic acid featuring two active hydroxymethyl groups; consequently, it serves as a key building block for synthesizing water-based polymer systems. It finds extensive application in water-soluble polyurethanes, polyesters, epoxy resins, general water-based resins, paints, coatings, inks, leather finishes, electronics, and adhesives. DMBA exhibits superior solubility in various solvents compared to DMPA, thereby significantly enhancing processing efficiency. DMBA is recognized as a new generation of eco-friendly, green chain extenders and internal emulsifiers for water-based polyurethanes. Its use in the production of water-based polyurethane adhesives eliminates the need for organic solvents, resulting in zero organic residue.

As carboxylic acid-type hydrophilic chain extenders, DMPA and DMBA have found widespread application in the production of water-based polyurethanes, thanks to their unique molecular structures and superior performance characteristics. Our company maintains a robust cooperative relationship with our manufacturing partners, ensuring a stable and consistent supply of these products over the long term. Furthermore, we offer a comprehensive range of complementary products for the water-based polyurethane resin, coating, and related industries—including DMPA-modified polyester polyols, water-based wetting and leveling agents, water-based antioxidants, water-based light stabilizers, as well as eco-friendly catalysts (such as organic bismuth compounds) and tin catalysts (e.g., T-12). value

Seeking a packaging seal that balances both strength and eco-friendliness? Water-based acrylics offer the perfect "best-of-both-worlds" solution! As a core raw material for sealing adhesives, they are widely utilized across diverse packaging applications—including food, express delivery, and daily chemical products. Whether applied to paper boxes, plastic bags, or composite film materials, they ensure a secure bond, effectively meeting the sealing requirements of various industries. Its advantages are truly noteworthy: First, water-based acrylics are eco-friendly and odorless, complying with food packaging safety standards to provide consumers with peace of mind. Second, they boast strong adhesion and rapid curing speeds; furthermore, their moderate viscosity prevents adhesive overflow after application, ensuring a clean seal while simultaneously boosting production efficiency. Additionally, they demonstrate exceptional resistance to both high and low temperatures, as well as superior anti-aging properties, effectively safeguarding packaging against bond failure during storage and transit to ensure long-term reliability and durability. Most notably, Water based acrylic box sealing adhesive integrate seamlessly with automated production lines, enabling packaging enterprises to achieve high-speed, stable manufacturing operations. This not only enhances packaging efficiency but also renders production costs more manageable. All things considered, selecting water-based acrylics as the raw material for sealing adhesives represents a truly high-value choice that successfully balances performance, environmental responsibility, and economic efficiency!

Leveraging their exceptional surface modification capabilities, water-based acrylic emulsions enhance both the physical properties and printability of coatings applied to paper. When incorporated into a formulation and applied to the paper surface, they form a protective film that improves surface strength, water resistance, and smoothness, while simultaneously reducing ink penetration to ensure superior print clarity for both cultural and packaging papers. When used in coatings for coated art paper or light-coated paper, combining them with titanium dioxide boosts whiteness, opacity, and print gloss, thereby meeting the demands of high-standard printing applications.
