3.Application behaviours:
When used in coating, paint and ink, it can obviously improve the dispersibility, antisettling ability, stability in storage in organic base for pigments, such as carbon black, phthalocyanin blue, titanium white, iron red, medium chrome yellow and etc. It also can improve good levelling and anti-sagging effect, reduce grinding times and time, improve film's adhesion and appearance and together with the effects such as fire retardant, anti-corrosion, improving adhesion and catalytic curing and etc. The detailed application behaviours are as followed:
3.1 It can improve the dispersibility and anti-settling ability for various kinds of phthalocyanin and metal pigment in organic phase. Normally the pigment treated by SN-DIS-124 has obvious anti-settling effect in epoxy resin.
3.2 It can obviously reduce the system viscosity for inorganic matter in organic phase and improve the filler's loading level.
3.3Aluminium hydroxide treated by SN-DIS-124 has thixotropy in amine-cured epoxy resin.
3.4 It can obviously improve colouring strength and reflecting force for coating, paint and ink, and improve adhesion between organic polymer and metals, glass, concert and other inorganic materials.
3.5 It has especially dispersion effect for titanium white. It can improve the titanium white dispersion in PP, hot melt lipids resin, epoxy resin, acrylic resin, alkyd resin and so on.
3.6 Silicon dioxide filler treated by SN-DIS-124 can replace all chromate rust inhibitor in chromate anticorrosive paint to avoid using expensive and high toxic chromate.
3.7 SN-DIS-124 has half-catalytic effect in melamine-cured or urea-cured alkyd resin, acrylic resin and polyester resin. Comparing with common catalyst, i.e., pTSA, SN-DIS-124 can sharply reduce the baking temperature.

4.Application range:
Nitrolacquer, alkyd coating, amino coating, chlorinated rubber paint, epoxy coating, phenolic coating, acrylic coating, PU, latex paint and so on, especially for Acrylic resin.

5.Usage and addition
5.1 After dissolve in isopropanol or other solvent with the proportion of 1:1, add into pigment and filler to grind. The recommended addition is 1% of pigment and filler. The best addition depends on the test result.
5.2 Directly add SN-DIS-124 into organic base in amount of 0.3 ~ 0.4% of total weight of coating, paint or ink, stir evenly and then add pigment and filler to grind and dispersion, other auxiliaries add several minutes later.

6.Actual effect
It can improve film gross by 20%, add fraction of coverage by 31%, and improve anti-torture and adhesion by 40%.
