ADD-3031 is a silicone surface additive to provide good substrate wetting of critical substrates and excellent anti-cratering by reduction of surface tension of the coating systems. It also improves surface slip, scratch resistance and anti-blocking properties. ADD-3031 is a heat resistant silicone additive, which shows no thermal decomposition at temperatures between 150°C and 230°C. Due to its low surface tension, it prevents floating of pigments, Bénard cells and pinholing. It is suitable for coatings and printing inks.

Applications & Uses

Coatings:
ADD-3031 is compatible with all medium- to high-polarity solvent-based systems.
It is suited for:
• Wood finishes based on unsaturated polyesters, polyurethane and nitrocellulose. It is also suitable for UV-curable wood coatings.
• Metal coatings, e.g. transportation coatings ADD-3031 improves leveling, mar resistance and acts as an anti-blocking agent. It can interfere with intercoat adhesion when recoated without sanding. If used in conjunction with ADD-3777, good flow and slip properties can be obtained, especially in top coats.
If air is introduced by the application equipment, small amounts of defoamers such as
ADD-2020 and ADD-2022 should be added.
• Acid-curing and stoving coatings
It can be added at any stage of manufacture as long as sufficient shear forces are applied to ensure uniform distribution of the additive.

Printing Inks:
ADD-3031 improves substrate wetting, leveling and increases scuff and mar resistance in inks and over-print varnishes. An applied film containing ADD-3031 is relatively insensitive to pinholing. It is especially effective in nitrocellulose-based flexographic inks and UV-curable over-print varnishes.
ADD-3031 can be added at any stage of the manufacturing process. In all cases care should be taken to ensure uniform distribution.
