3. Compatible with Resins

Good compatible with acrylic resins, amino resins, aldehyde resins, alkyds(short, medium and long), nitrocelluloses epoxy, polyester, epoxy resins, and phenolic resins, etc.

 

4. Properties

TA-100-40 has excellent wetting and dispersing performance in pigments. It can enforce tinting function, improve gloss, reduce haze, and improve transparence of pigments, especially show good effects upon phthalocyanine, iron oxide pigments and high surface energy black carbon, etc. It can shorten the grinding time of pigments and improve efficiency, in addition to prevent pigment particles from re-agglomerating. It can increase the loading of pigments because of its good function to effectively change the rheological property of pigments. Good flowing property can reduce VOC. It shows excellent performance in transparent pigments pastes and enables it a good gloss and particle size distribution, in addition to better transparency and stability in storage and transportation.

 

5. Loading Recommendation

Weight percentage of dispersant = specific area (m²/g)/5

Recommended loading of dispersant: TA-100-40/ weight percentage of pigment

Organic pigment: 8~15%

Inorganic pigment: 1~8% (in transparent iron oxide pigment: 7~15%)

General black carbon: 10~40%

High surface energy black carbon: 40~100%

 

6. Guidelines for Use

TA-100-40 is firstly incorporated into grinding binders.

Because TA-100-40 offers a good performance of reducing viscosity, a better method of obtaining a desirable viscosity is to increase loading of pigments.

 

7. Applications

High-end paints (i.e. automotive coatings and refinishing), general industrial coatings, coil coatings, aluminum coil coatings, marine coatings, universal tinter, solvent-based industrial coatings, plastic coatings, furniture coatings, and inks, etc.
