Characteristics

PRO-SUR causes only a slight reduction in surface tension. It is a silicone leveling additive that has a defoaming effect or does not stabilize the foam or only slightly, depending on the polarity of the paint system. PRO-SUR is thermostable up to 250 °C. PRO-SUR can impair interlayer adhesion if the dosage is too high.

Recommended additional amounts

0.01-0.5% additive as supplied on the total formulation, depending on the system and layer thicknesses.

Processing

The addition should be made at the start of production. Subsequent addition is possible, but PRO-FLOAT must be incorporated intensively.

Use during the production process

PRO-FLOAT is more optimally added after the dispersing/grinding batch, that is, when the dispersing/grinding process has finished, after cooling and before letdown, PRO-FLOAT is added with stirring. Then the approach is completed with the remaining components of the recipe. After completion, the approach should rest (mature) for 24 hours so that the full effectiveness of the PRO-FLOAT can unfold.

Use as a post-additive for subsequent incorporation

If PRO-FLOAT is to be used as a post-additive, PRO FLOAT is added to the finished mixture while stirring and then mixed for 10 minutes at 10 - 15 m/sec. incorporated. After completion, the approach should rest (mature) for 24 hours so that the full effectiveness of the PRO-FLOAT can unfold.

Storage recommendation

Stir well before use. Keep container in a cool, well-ventilated place. Occasionally, traces of water may be contained, which have no influence on the effectiveness of the product and the quality. In order to maintain the product quality, the original container should be closed again immediately after each removal. The properties of PRO-FLOAT described are retained for at least 2 years if stored properly.
