Melamine-based superplasticizers are dry, free-flowing powders produced through the spray-drying of sulfonated polycondensation products based on melamine. SMF powder superplasticizer is particularly well-suited for reducing water content and enhancing the plasticity of cement and calcium sulfate-based blended materials. It maintains a white appearance and exhibits robust water-reducing properties without introducing air. With its low chloride ion content, it offers excellent compatibility with various types of cements, ultimately contributing to the improvement of early strength, impermeability, workability, water retention, and steam curing capabilities. Jufu Chemical is one of the leading sulfonated melamine formaldehyde manufacturers in China. RFQ Today!

Application of Sulfonated Melamine Formaldehyde Resin(SMF Powder)


1. Ceramic and cement dispersant

Melamine formaldehyde resin sulfonate is a good anionic surfactant with surface activity and other valuable properties. It is often used as a high-efficiency dispersant or water reducer in ceramics, cement, and concrete at home and abroad. Its mechanism of action is mainly: this type of water reducing agent has the function of adsorption, dispersion and lubrication, so it can improve the workability of concrete with less water, so as to achieve the purpose of water reduction. As the water-mixing ratio decreases, the pores in the concrete decrease, making the cement denser, increasing its strength, and reducing the amount of cement used. Due to the infiltration of water reducing agent, the growth of cement hydration products is slow, and the network structure of sulfonated concrete is denser, which is conducive to the increase of medium and long-term strength of concrete.

2. Paper Industry

The principle and performance characteristics of being used as a wet strengthening agent and water-repellent agent Because melamine-formaldehyde resin contains methylol, it can form an etherified structure between fiber bundles, and the cross-linking between different molecules produces water resistance, making the paper It can achieve the effect of humidifying strength, so it is mainly used as wet strengthening agent and water-resistant agent in the paper industry.

3. As wood adhesive

In the wood industry, melamine-formaldehyde resins are mainly used as adhesives. Due to its greater chemical activity, when it penetrates into wood products, the cross-linking and hardening speed is faster, and it can be heat-hardened or room-temperature hardened without other hardeners, thereby producing a bonding effect. Due to its good thermal stability, water resistance and chemical resistance, it is widely used in wood-based panels, wood, construction, paper packaging and other fields.

4. Finishing agent for fabric printing and dyeing

In the textile industry, melamine formaldehyde resin and its derivatives are important raw materials for preparing fabric printing and dyeing finishing agents. Its mechanism of action is that it can be used as a surface modifier and coupling agent for fabrics, thereby improving the anti-shrinkage, anti-wrinkle, and washable properties of cotton fabrics.
