Applications

PowerSorb™ 384-2 is recommended for: automotive coatings, general industrial applications, i.e. coil coatings, wood coatings.

The liquid form of PowerSorb™ 384-2 provides easy incorporation into water borne systems. The performance provided by PowerSorb™ 384-2 can be enhanced when used in combination with a HALS stabilizer. These combinations improve the durability of clear coats by inhibiting or retarding the occurrence of failures such as gloss reduction, cracking, color change, blistering and delamination. The amount of PowerSorb™ 384-2 required for optimum performance should be determined in trials covering a concentration range.

Packings

PowerSorb™ 384-2 is supplied in 25 kg drum.
