Special Properties and Uses

• Additol XL 6557 provides pigment wetting, low paste viscosity, and good pigment stabilization in pigment pastes. The suggested use is as grinding medium for pigment pastes. Combination with co dispersants is strongly recommended to improve pigment stabilization and mill base viscosity reduction.
• The polymer backbone of Additol XL 6557 is modified with pigment anchoring groups to support pigment wetting; due to its resin-like structure it maximizes the overall paint performance. The multifunctional drying and crosslinking concept allows co-crosslinking of the pigment pastes into 2K PUR or amino crosslinking baking systems. Further, if used inside an airdrying alkyd, the material supports surface hardness via unsaturated double bounds.
• Finished coatings tinted with Additol XL 6557 have high hardness, yellowing resistance, high gloss, good drying properties, good mechanical properties, high water resistance and/or excellent weather resistance.
• In solvent borne industrial application such as coil coatings, marine and heavy duty anti corrosive paints, agriculture, industrial wood, and other metal coatings, the pigment pastes based on Additol XL 6557 support chemical and physical properties of the final paint system.
