FAQ
Floor Coatings
Which additive can be used as a leveling agent in polyaspartic-based floor coating formulations to improve surface appearance without causing any adverse effects (such as cloudiness)?
Application:Floor Coatings
Reply: Tech-214N is a silicone-based surface additive that strikes a balance between excellent leveling properties and additional defoaming effects. You may also want to try the non-silicone leveling agent Tech-154N.
What additives can be used to prevent leveling and wetting issues in water-based floor coating formulations?
Application:Floor Coatings
Reply: As water-based formulations dry, localized variations in surface tension occur within the liquid film. This can lead to poor leveling or other surface defects. Additives such as Tech-2849N help address these issues and prevent poor surface appearance after the film has completely dried.
Which rheological additives can be used in water-based polyurethane formulations to achieve good flow properties during roller application without leaving any roller marks?
Application:Floor Coatings
Reply: To achieve optimal processing performance, perfectly balanced rheological properties are required. The combination of Tech-9048 and Tech-9040N meets this requirement without causing any adverse effects.
What additives can be used in the formulation of water-based epoxy floor coatings to prevent settling?
Application:Floor Coatings
Reply:
This resistance to sedimentation can be achieved by using specially developed additives such as Tech-9022W, which form a network structure within the system and induce pseudoplasticity. Controlled flocculating wetting and dispersing agents, such as the multifunctional Tech-60701, operate on a similar principle. These additives cause dispersed particles to aggregate into a loose structure, which can sometimes result in higher viscosity and good resistance to sedimentation.
In a water-based epoxy floor coating formulation, which defoaming additive can be used to prevent foam bubbles without negatively affecting the self-leveling properties?
Application:Floor Coatings
Reply: Tech-371W is a silicone defoamer that significantly improves the defoaming performance of filled water-based epoxy self-leveling formulations. It is recommended that the defoamer be added during the production process.
When using a roller-application formulation, what type of additive can be added to a water-based polyurethane clear coat to control bubble formation?
Application:Floor Coatings
Reply: The air present in these systems can significantly affect the performance of the final coating. Polyurethane flooring systems combine an attractive appearance with excellent mechanical properties. The use of degassing additives, such as Tech-328W, can help improve these properties by enhancing the degassing of the system after application and even during production.
What additives can be added to polyurethane casting resins to control bubble formation, and to ensure that more uniform, fine bubbles form when water is added to the formulation?
Application:Floor Coatings
Reply: The air content in these systems can significantly affect the performance of the final coating. Polyurethane flooring systems combine an attractive appearance with excellent mechanical properties. As a result, these systems are suitable for both industrial and decorative applications. Good application properties require low viscosity, and for ease of handling, fillers or pigments must exhibit good stability. The use of degassing additives, such as Tech-30881, can help improve these properties by enhancing the degassing of the system after application and even during production.
Which additive can be used as a defoamer in formulations for polyaspartic-based colored floor coatings?
Application:Floor Coatings
Reply: Polyaspartic formulations offer unique properties that significantly reduce drying time or improve the final surface appearance. To prevent the formation of unwanted foam, Tech-498 can be used in colored polyaspartic formulations. Using Tech-498 results in a foam-free formulation.
