Dispersed anti-sedimentation agent LD-1291S

1. Summary

Used as a dispersing abrasive, anti-settling agent, and anti-floating agent for paints, coatings, inks and similar surface coatings.

2. Components    

Higher aromatic solution of 50% electron neutral salts made from polycarboxylic acids and amine derivatives.

3. Typical physical and chemical data

Appearance: brown transparent liquid

Active part: 48-50%

Flash point: 68-72°C

Density (20°C): 0.9-1.1/cm3

Acid value: 55-58mgKOH/g

Refractive index (20°C): 1.494-1.502

4. Application

LD-1291S is a commonly used additive in solvent-based coatings, especially effective in resin-based coatings such as alkyd resins, alkyd/amino resins, acrylic and epoxy resins, chlorinated rubber/polymeric oils, etc. Some linear resins with hydroxyl groups (such as Bayer's DESMOPHEN resin) can produce thixotropy when used in conjunction with LD-1291S.

In addition to being an effective dispersant, LD-1291s can significantly reduce the tendency of the bottom of the coating to rust, especially when applying anti-corrosion paint on wet surfaces such as steel. In oil-based paints, even the presence of tung oil reduces the possibility of skinning and improves flow.

5. Prefabricated gel as organobentonite

LD-1291s is an excellent organically modified bentonite gelling agent, which has the following advantages:

1. Pumpable gel consistency

2. Easy to add to paint

3. Improve the stability of the gel

4. Precast gels can be added later

5. Easy to disperse

6. It has anti-sinking and anti-floating effect

Preparation recipe for precast gel:

80-87% solvent (200# solvent gasoline, xylene, toluene)

8-10% organically modified bentonite

3-10% LD-1291s

6. Packaging and storage

1. 50 kg reinforced plastic drum or according to customer requirements.

2. Sealed and stored at room temperature for one year.

3. Color change will not affect the quality.
