CHEMICAL STRUCTURE

It has an anionic character, a high concentrated solution of special oil alcohol sulfates in suitable solvents.

EFFECT AND THE FIELD OF APPLICATION

As SEMSOL - S is a good surface active agent, it increases pigment wetting, and is an effective anti settling agent used in every type of paints even in low viscosity and heavy pigments containing paints.

Suitable for the following systems:

Every type of alkyd resin systems
Chlorinated rubber systems
Urethane oil resins which doesn't contain free iso-cianat groups
Epoxy resins
Asphalt and bitum paints
Nitrocellulose lacs
Acrylic/melamine resins
Acrylic,thermoset resins
Acrilic,air drying resins

Semsol – S is NOT suitable for the following systems.

Polyurethane systems
Clyclo-rubber paints
Unsaturated polyesther based paints

SEMSOL – S is used with many pigments and fillers like barit, calcite, talk, litapon, titan diokside, inorganic and organic. It is not recommended to use in metalic pigments like alluminium paints and zinc powder.

SEMSOL - S doesn't effect the paints properties like gloss, flow, drying, stickness. Doesn't affect with the heat formed by pigment diffusion. As it has an anionic structure, we do not recommend to use with agents containing cationic structure. It can be used alone or with surface active substances.

SEMSOL – S must be added to the mill base to improve effectiveness. The addition while producing pigment paste gives the best result.

It can be used in preparing benton gels as shown in the below formulation:

85-87 of weight solvent (white spirit, xylene, toluol)

8-10 of weight organophilic bentonite

5-3 of weight SEMSOL S

Total weight 100

RECOMMENDED DOSAGE

It changes over finished paint between 0.1% and 0.5% . In presence of heavy pigments it may be %1. It is suitable to find the best dosage by starting from the minimum amount and increase the amount slowly.

STORAGE

SEMSOL S can be stored for 1 year in closed package at room temperature in a dry place.

PACKAGE FORM

In 60 kg.original packages.
