DELTA-DC® 4207 

DELTA-DC® 4207 is a multi-purpose wetting and dispersing additive for solvent-based and solvent-free coatings to improve pigment wetting, reduce the time required for the grinding process and stabilize the pigment dispersion. It is especially developed for solvent-based architectural paints and general industrial coatings to stabilize TiO2, extenders and other inorganic and organic pigments. DELTA-DC® 4207 can be used in coatings and printing inks. 


Specifications:

Appearance :Clear to slightly hazy and brownish liquid 

Amine value :80-90 mg KOH/g 

Active ingredients :>98% 



Applications and usage: 

Coatings 

DELTA-DC® 4207 is a highly concentrated wetting and dispersing additive for inorganic pigments (especially TiO2) and extenders. The use of DELTA-DC® 4207 results in the following advantages: 

    ●    Reduced dispersion time 

    ●    Increased gloss 

    ●    Decreased flooding of pigments 

DELTA-DC® 4207 is a multi-purpose additive and can be used in any solvent- or solvent-free resin systems. It is well-suited for the production of high-solids and aromatic-free architectural paints. 

White base paints stabilized with DELTA-DC® 4207 have better color acceptance and do not demonstrate flooding and floating when tinted with universal colorants. DELTA-DC® 4207 is suitable to formulate pigment concentrates based on long-oil alkyds. 

DELTA-DC® 4207 should be added prior to the dispersion process. 

0.8-1.5% on TiO2or extenders 

3.0-5.0% on inorganic pigments 

5.0-9.0% on organic pigments or carbon blacks 


Printing inks 

DELTA-DC® 4207 is a dispersant for enhancing the dispersion of inorganic pigments (particularly TiO2) in solvent-based media. This results in: 

    ●    Improved dispersion or suspension stability 

    ●    Improved color strength 

    ●    Improved opacity with TiO2 

    ●    Lower viscosity and/or higher pigment loading 

    ●    Reduced dispersion time 

    ●    Higher gloss 

When used in whites, DELTA-DC® 4207 will improve the co-stabilization of added organic tinting or toning bases (e.g. color acceptance) resulting in reduced risk of pigment separation. 

It has broad solvent compatibility and is suitable for use in both alcohol- and acetate-reduced nitrocellulose printing inks and pigmented bases. DELTA-DC® 4207 is well-suited to packaging flexographic applications. 

For best results, DELTA-DC® 4207 should be combined with the pre-blended liquid portion of the mill-base formulation before addition of the pigment. 

0.8-1.5% on TiO2 

3.0-5.0% on inorganic pigments 

5.0-9.0% on organic pigments or carbon blacks 


Safety and Handling: 

DELTA-DC® 4207 should be handled in accordance with good industrial practice. Detailed information can be found in the Safety Data Sheet. 

Storage: 

DELTA-DC® 4207 should be stored in a cool dry place. When kept in an original unopened container, it will keep up to 5 years from the date of manufacture. The production date is indicated on the container. 

Packaging: 

55 kg and 190 kg non-returnable metallic containers.
