DELTA-DC® 4066 is a wetting and dispersing additive for enhancing the dispersion of inorganic pigments. It is designed to prevent flooding and floating and hard sedimentation.
Composition :High molecular weight unsaturated carboxylic acid
Specific gravity @ 20°C :ca. 0.95 g/cm3
Flashpoint :40 °C
Appearance :Transparent, slightly brownish liquid
Acid value :120-160 mg KOH/g
Active ingredients :52%
Applications and usage:
DELTA-DC® 4066 has a chemical structure that is similar to that of DELTA-DC® 4065, but does not contain the organically modified polysiloxane.
Like DELTA-DC® 4065, DELTA-DC® 4066 can be used to improve the pigment wetting and stabilize the pigment dispersion.
It produces a controlled flocculation of pigments and extenders and therefore prevents flooding/floating and hard sedimentation. DELTA-DC® 4066 is also used in amine-neutralized aqueous coatings, but it is not compatible with mineral spirits or paints, which are diluted with mineral spirits.
DELTA-DC® 4066 is suitable for medium- to high-polar systems such as:
● Nitrocellulose systems
● Alkyd/amino resin combinations
● Polyurethane and chlorinated polymer systems
● Acrylic polyisocyanate systems (two-pack acrylics)
DELTA-DC® 4066 is particularly effective in preventing flooding of titanium dioxide in combination with other color pigments.
It is often used in conjunction with high molecular weight dispersants such as DELTA-DC® 3011, DELTA-DC® 3046, DELTA-DC® 3047 or DELTA-DC® 3401. However, the performance of DELTA-DC® 4065 in most cases will be slightly better.
When used in anti-corrosion primers, in many cases the protective properties are enhanced. DELTA-DC® 4066 should be added prior to the dispersion process.
