Introduction of DPGDB plasticizer for Gypsum-based formulations

DPGDB (Dipropylene Glycol Dibenzoate),Ecod-flex 342 is a plasticizer?used in gypsum-based formulations, particularly in gypsum wallboards, coatings, and joint compounds.

Gypsum joint compound, also known as drywall mud, is a white powder that's mixed with water to create a paste. It's used to fill gaps, cover screws, and create a smooth surface for paint or wallpaper.?

How DPGDB is Used in Gypsum Products.

1. As a Plasticizer?– DPGDB improves the workability and flexibility of gypsum pastes, making them easier to apply and reducing brittleness.

2. Enhancing Hydration Control?– It can help in controlling the setting time of gypsum by modifying the water interaction.

3. Reducing Cracks & Shrinkage?– It enhances the elasticity of gypsum, minimizing cracks that may develop during drying.

4. Used in Joint Compounds?– DPGDB is also used in gypsum-based fillers and joint compounds to enhance adhesion and flexibility.

Advantages of DPGDB Compared with Other Plasticizers.

1. Better Performance Than Traditional Phthalates?

1. Many traditional plasticizers like DOP (Dioctyl Phthalate)?have regulatory concerns regarding toxicity. DPGDB is a safer alternative?with lower health risks.

2. Lower Volatility & Better Stability?

1. DPGDB has lower volatility, making it more stable in long-term applications.

3. Improved Flexibility Without Affecting Setting Time?

1. Some plasticizers may delay setting time excessively, but DPGDB provides a balanced setting profile?while still improving flexibility.

4. Compatibility with Other Additives?

1. Works well with other gypsum additives?like dispersants, retarders, and accelerators, making it versatile for different formulations.

How to Use DPGDB in Gypsum Formulations

· Typical dosage levels depend on the application, but generally range from 0.5% - 5% of the gypsum formulation.

· It can be mixed directly into the gypsum slurry?along with other additives.

· Works best in combination with water reducers or superplasticizers?to optimize flowability.
