Kollicoat® Smartseal 30 D is insoluble in water (neutral pH) and dissolves quickly under protonation at pH-values of 5.5 and below due to the defined number of basic functional groups. It is a co-polymer comprising methyl methacrylate (MMA) and diethylaminoehtylmethacrylate (DEAEMA) in the ratio 6:4. Kollicoat Smartseal 30 D is an aqueous polymer dispersion (latex) with a faint characteristic odor. It contains approx. 0.6 % macrogol cetostearylether 20 and approx. 0.8% sodium laurylsulfate.

Kollicoat® Smartseal 100 P is a spray dried powder of a methyl methacrylate (MMA)and diethylaminoethyl methacrylate (DEAEMA) copolymer. The molar ratio of the monomers MMA and DEAEMA in the copolymer is 7:3. The powder contains approx. 2% macrogol cetostearyl ether and approx. 2.5% sodium lauryl sulfate. It is white and has a pleasant characteristic odor.

Kollicoat® SR 30 D is an aqueous dispersion with a solids content of 30%. The low viscosity product has a weak characteristic odor and a milky white or slightly yellowish appearance. The dispersion consists of about 27% polyvinyl acetate, 2.7% povidone and 0.3% sodium lauryl sulfate. Kollicoat® SR 30 D is miscible with water in any ratio while retaining its milky-white appearance. Mixing the product with ethanol or isopropyl alcohol in a 1:5 ratio produces a slightly turbid and somewhat viscous solution, a solution in acetone is more turbid. On addition of further organic solvents the polymer precipitates out but then dissolves when further solvent is added. It is insoluble in dilute alkaline or acidic solutions.
