We recommend using Tech-2033, Tech-2733, and Tech-2041. These products are compatible with a wide range of systems and provide a pleasant tactile experience.
We have encountered flow issues in a solvent-free radiation-curing system, but this system does not allow the use of silicones.

We recommend using Tech-1056 (100% active ingredient) and Tech-1061 (100% active ingredient) to improve the leveling of solvent-free radiation-curable systems. These products offer good compatibility and will not cause haze in the final coating system. The recommended additive dosage is 0.1–1.0% (as purchased) based on the total formulation.
I have developed a solvent-based, two-component polyurethane matte finish that uses untreated silica matting powder to achieve a matte finish. When sprayed onto wood panels, the surface exhibits flaki

Tech-220 and Tech-223 are relatively mild silicone surface-active agents that balance surface tension differences throughout the coating as the solvent evaporates, thereby significantly improving the orientation of the matting agents without causing foaming. The recommended usage is 0.2–0.5% of the total formulation based on the purchased form.
I'm developing a water-based floor paint. The defoaming effect was good at first, but after a while, the standard defoamer I was using stopped working. Do you have any good suggestions?

Tech-3904 is a multipurpose defoamer that offers exceptional long-term effectiveness at both high and low storage temperatures. This defoamer has a wide range of applications. Its advantages include good compatibility (fewer defects such as pinholes or cloudiness), ease of incorporation, and the ability to be added later in the process.
A major challenge I am currently facing is dispersing titanium dioxide in various solvent-free radiation-curing systems; in particular, the viscosity-reducing effect and long-term storage stability ar

Tech-5010 is a solvent-free wetting and dispersing additive specifically designed for dispersing titanium dioxide. It provides excellent viscosity reduction, high gloss, high hiding power, and long-term storage stability. The recommended dosage is 1.5–3.5% by weight of the pigment. The formulation and chemical composition of Tech-5010 make it particularly suitable for solvent-free radiation-curable systems.
While developing a new type of solvent-free, radiation-curable clear topcoat, we encountered foaming issues during production and application. What product would you recommend for defoaming?
Application:Defoaming

Tech-30881 defoamers are particularly suitable for solvent-free, radiation-curable high-gloss clearcoat systems. They provide excellent defoaming performance, have no adverse effect on the transparency of the paint film, and do not cause pinholes. The recommended usage of this additive is 0.1–0.4% of the total formulation, based on the supplied form.
There is a growing demand for the development of solvent-free, radiation-curable coatings with color pigments, but selecting the right wetting and dispersing agent for this purpose is challenging.

Tech-6013 is a solvent-free wetting and dispersing additive that provides excellent viscosity reduction and long-term stability in pigment dispersion, while also improving tinting strength, transparency, and gloss. Due to its broad compatibility, it can be used with a wide variety of common oligomers and monomers. The recommended usage is 2.5–8.0% (solid-to-solid) for inorganic pigments and 15.0–60.0% (solid-to-solid) for organic pigments or carbon black.
We have developed a wide range of clear and tinted water-based wood finishes, and we are currently looking for a versatile rheological additive to adjust the viscosity in the container.

Tech-9035 is an associative, medium-shear thickener specifically recommended for adjusting the in-can viscosity of clear and pigmented water-based wood coatings. The performance of these rheological additives is not affected by pH and has no adverse effect on the gloss and transparency of the final coating system. The recommended usage is 0.3–2.0% of the total formulation based on the supplied specification.
