Applications


Ambient-curing Plastic Systems

Special Features and Benefits

MOK-5140S improves the dispersion of all conventional fi llers, such as calcium carbonate and aluminum hydroxide. It reduces the viscosity of the filled resin, which enables an increased fi ller content. In the majority of cases, the settling of the fi ller is significantly reduced during storage and when processing. MOK-5140S is suited to stabilizing pigments in gel coats. The additive also contains a small quantity of a polysiloxane copolymer to reduce fl ooding and floating. This prevents the formation of Bénard cells and improves the surface slip and leveling.

Recommended Use

The additive is particularly recommended for unsaturated polyester resins, gel coats, acrylic, polyurethane and epoxy resins and displays the highest effi ciency in all applications.




Recommended Levels

0.5-1.5 % additive (as supplied) based upon the fi ller.

The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.

Incorporation and Processing Instructions

For optimum performance, the additive should be added before the solids.


Coatings Industry

Special Features and Benefits

The additive provides a targeted, controlled fl occulation of the pigments. The system builds bridges between the individual pigment particles, thereby creating three-dimensional networks. This controlled

fl occulation of the pigments primarily prevents fl ooding/fl oating along with settling and sagging. MOK-5140S is suited to stabilizing pigments in industrial coatings and architectural coatings. It increases gloss, prevents fl oating and reduces the millbase viscosity. The additive also contains a small quantity of a polysiloxane copolymer to reduce flooding and fl oating. This prevents the formation of Bénard cells and improves the surface slip and leveling, and also the orientation of matting agents and aluminum pigments.

In the majority of cases, it is no longer necessary to add the silicone additives which are usually required.

Recommended Levels

Amount of additive (as supplied) based upon pigment:

Inorganic pigments: 3-10 %

Titanium dioxides: 1-3 %

Organic pigments: 8-16 %

The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.

Incorporation and Processing Instructions

For optimum performance, the additive must be incorporated into the millbase before addition of pigments.
