This rage represets specialty additives with uique chemistries ad exceptial techical features. MULTI-PUPOSE ADDITIVES (DELTA-S 5225 & DELTA-S 522) DELTA-S 5225 is a multi-fuctial additive as it ca be used as well as: Clr acceptace imprver Sle dispersi ctrl additive fr the maufacturig f uiversal clrats Dispersat f chice fr trasparet ir xides DELTA-S 522 is a multi-fuctial additive as it ca be used as well as: Clr acceptace imprver Dispersat f chice fr trasparet ir xides Excellet dispersi ctrl additive fr irgaic pigmets ad exteders i waterad slvet-based systems Dispersat f chice the preparati f slurries ad mattig aget dispersis Bth DELTA-S 5225 ad DELTA-S 522 are % active, APE-free dispersi ctrl additives. They based usaturated fatty acids havig plar heads based tertiary amies. The hydrphbic chais have usaturated character which allws the additive t be liquid at rm temperature (easy hadlig). I additi, the usaturati prvides dryig prperties by crss-likig i the presece f xyge. The hydrphilic heads (tertiary amies) allw the additive t be effective dispersi ctrl additive by actig as excellet achrig grups. The achrig grups used i DELTA-S 5225 are similar t thse f ur high mlecular weight dispersi ctrl additives (DELTA-DC 3-series) ad hece have strg affiity twards pigmet surfaces (Irgaic, Orgaic ad carb black pigmets). DELTA-S 522 has special achrig grups allwig the additive t drastically reduce the viscsity f irgaic pigmets ad exteders. Slurries ad highly pigmeted ir xide r titaium dixide pastes ca be prepared by usig e sigle dispersi ctrl additive. Clur acceptace It is pssible t imprve clur acceptace f base paits (slvet ad waterbased paits) whe usig bth DELTA-S 5225 r DELTA-S 522 as pstadditives by prevetig the de-wettig f surfactats (surfactat strippig) used fr the frmulati f uiversal clrats..5-.5 parts by weight f either DELTA-S 5225 r DELTA-S 522 it the white base pait (alkyd r emulsi base) ca make a wrld f differece.

Uiversal clrats fr architectural paits Prducti f clrats is essetial fr titig f the architectural paits. Titig systems require that the pre-dispersed clrats ctai the same resi as the base (ld system). Ideally these titig pastes wuld be cmpatible with water-based as well as slvet-based bases. With DELTA-S 5225, yu ca frm w ward frmulate yur 6 clrats withut ay resi ad with ly e dispersi ctrl additive. Makig uiversal clrats has ever bee s easy!

MODY 4 WD is the water-dispersible versi f MODY 4 suitable fr water-reducible catigs. ANTI-GEL ADDITIVE DELTA-S 57 is a ati-gel aget ad viscsity stabilizer fr air-dryig ad stvig catig systems. It delays/prevets thickeig, which ca ccur as a result f xidati r cdesati f the bider. It als reduces the reacti f the pigmets with the vehicle. It is usually added prir t gridig, but already gelled materials ca be restred t prcessig viscsity by the additi f DELTA-S 57. SYNEGIST ADDITIVE DELTA-S 5745 is a plar pigmet derivative (dyestuff), which is used i cjucti with a high mlecular weight dispersi ctrl additives (DELTA-DC 3-series) t eable efficiet achrig f the dispersat t the pigmet. It is primarily used with certai difficult -plar rgaic pigmets (Phtal-cyaie blue ad gree pigmets) ad carb black pigmets, which d t eable gd iteracti with cmm dispersat achrig grups. Addig betwee.5% ad.% i the frmulati alg with e f DELTA-DC 3-series dispersi ctrl additives will eable viscsity reducti i the mill-base ad therefre imprve the dispersi prcess. METAL-FEE ACCELEATO AND STABILIZE MODY AWD is a cst-effective metal-free acceleratr ad stabilizer fr water-bre catigs. May waterbre catigs are pre t lss-f-dry up exteded strage. These cmpuds crdiate with the dryig metals, specifically cbalt ad magaese, ad prmte sigificatly faster dry. This cmplexig acti prtects the active metals frm hydrlysis ver time ad miimizes lss-f-dry i the custmer s waterbre frmula. This ehaced activity ca als be see i imprved water resistace ad higher glss. THIXOTOPIC ADDITIVE DELTA-S PN is a liquid thixtrpic additive that builds its thixtrpic structure thrugh iteracti f its mlecules with the reactive grups distributed ver the plymer f the latex emulsi r thickeer. This iteracti ccurs thrugh hydrge ad cvalet bdig with active sites f the plymer, thus creatig a etwrk structure. The achieved thixtrpic behavir f the catig results i: High viscsity at rest ad durig strage prevetig settlig r sedimetati Cessati f pigmet separati (mstly i ca) i frmulatis ctaiig mre tha e type f pigmets Up shear ad durig catig applicati, the etwrk structure almst cmpletely breaks eablig gd flw ad levelig f the catig. ight after shear remval, the etwrk structure rebuilds agai prevetig saggig f the catig. DELTA-S PN des t thicke water by itself. It eeds a bider ctaiig system t give its effect. The rmal usage level fr DELTA-S PN is betwee.5% ad 2.% (as supplied) up ttal frmulati weight. 6
