DISPARLON _PFA-250(Anti-sagging / Anti-settling agent)

DISPARLON PFA-250 is a thixotropic agent in paste form consisting of a specially prepared amide wax activated inaromatic free solvent. It is easily incorporated into a variety of vehicles and/or solvent and develops exceptionallystrong and long-term retained thixotropic structure.

ADVANTAGES● Strong anti-sagging / anti-settling effect● Improve orientation of metal pigment● Ready to use (No need for activation process)APPLICATIONSDISPARLON PFA-250 can be used in almost all solvent based synthetic resin coatings. Particularly recommended
are heavy duty paints such as Epoxies, Tar/epoxies, Urethanes, Chlorinated rubbers, Vinyls, Unsaturated polyesters,Acrylics and baking enamels such as Acrylic/Melamine for automotive top coat etc..
INCORPORATION
Additive levels : Preferable dosage level per total formulation is 1.0 ~ 5.0 wt.% for anti-sagging and 0.5 ~ 2.0wt.% for anti-settling. However, dosage level may fall out of these ranges depending on yourformulation. The optimal level should be determined by your laboratory tests.
Method: High speed dissolver is recommended.
Dispersing
temperature: Amide component may form particles if it is dissolved into a formulation and later
precipitated during dispersing process. Standard dispersing temperature is between
the room temperature and 50°C to prevent particle generation. Please be careful of thedispersing temperature because particles may occur at the upper side of the standard
temperature range mentioned above if a formulation contains large amount of polar
solvent.

TYPICAL PROPERTIES
Appearance: White to Light yellow paste

Non-volatile matter: 20% by weight

Solvent: Butyl acetate/ 1-Butanol

Particles may occur in the paste during storage at a low temperature less than 15°C because of the crystallizationof its ingredients. In such case, please warm the vessel in a heating chamber at the temperature between 35°C
and 40°C for 24 to 48 hours just before using it.
CAUTION
Amide wax may cause low surface tension. Please make sure to check recoatability especially in alkyd melamineor oil modified alkyd baking systems.
