2 Coalescing, as supplied, will not form a film at room temeprature. Coalescing solvents must be added to formulas. The amount and type of cosolvent will depend on the different cosolvent used. The following solvents have proven to be compatible with NeoRez R DPM NMP TPM DE DPnB PNP dipropylene glycol methyl ether n-methyl-2-pyrrolidone tripropylene glycol methyl ether diethylene glycol ethyl ether dipropylere glycol n-butyl ether propylene glycol n-propyl ether Flow and Wetting Agents To improve wetting and flow out on various plastic substrates the following flow and levelling agents are recommended: Flow Aids BYK 346 BYK 348 Dow 67 Dynol 604 Suggested Level Flatteners Flatteners and combination of flatterers can be used to lower the gloss of coatings based on. Bermasilk MK was found to be the flattener of choice, based on its ability to lower the gloss without influencing the rheology or requiring additional solvent. A combination of Pergopak M3 and TS-100 (2/1) was found to be most efficient in gloss reduction and abrasion resistance. Addition of a defoamer (e.g. BYK shear-efficient) is highly recommended to avoid airentrapment during or after TS-100 addition. Additional amount of co-solvents maybe needed based on the oil absorption of the flattener. Starting point level of 5% wt. silica is recommended for gloss reading of 3 to 5 at 60 geometry. The following flatteners are also recommended: Page 2 of 5 Bermasilk MK Acematt TS-100 Acematt OK 412 Gasil Ijl Pergopak M3
