Ingtrone has introduced a new type of anti-light powder with high transparency and soft touch

ACEMATT®3400 is a new light-dissipation powder product in the Created ACEMATT® product line, developed specifically for high-transparency varnishes and coatings with smooth surfaces and soft touch.ACEMATT®3400 is a surface-treated, medium particle size (average particle size of 7.5 m) of the gas-phase method silicon dioxide anti-light powder. Lower fineness makes the coating surface very smooth, combining excellent optical properties and

.
this high-light-dedensing powder is ideal for a wide range of transparent, water-based and solvent-based coatings, typical applications including
wood coatings, plastic coatings and automotive coatings. In addition, it can be used in high solids and low VOC formulations.in fluidology, the special reprocessing of ACEMATT®3400 prevents the adsorption of the combined thickener in the water-based coating system. Similarly, when used in specific polyurethane systems, it can also improve soft touch.The ACEMATT ®3400 can be easily added to the formulation without the need for high shear force or the use of bead mills. In addition, the ACEMATT ®3400 can be added to the formulation at the back of the coating production process, allowing for post-adjustment of gloss.

2. Product characteristics
(1) gas phase process - high de-light efficiency, high transparency
Silicon dioxide anti-light powder basic manufacturing processes are two: wet process and gas phase process. Wet process can be divided into gel process and precipitation method. Created to take the lead in the use of gas phase process, compared to precipitation method and gel method process, the use of gas phase process production of light-reducing powder has a very high degree of transparency, at the same time in the light-down efficiency also has a great advantage.

(2) PDMS modified in solvent-based 2K PU elastic paint - soft touch, scratch resistance, good suspension performance,
prevents adsorption of the combined thickener in the water-based
ACEMATT®TS 100 has been successfully developed by ACEMATT®3400 due to its coarse particle size and unsyswered surface treatment, which are often challenged in the sense of feel, suspension properties and use in some applications with thin coatings.
ACEMATT®3400 surfaces are treated with special organic polymers (PDMS-polydymethane derivatives), making the coating surface very smooth and significantly improving scratch resistance on the coating surface. At the same time, the special PDMS surface treatment improves the compatibness with the system, the subsidion problem is improved, and the suspension performance is greatly improved. In addition, the surface treatment provides a special soft feel, coupled with the adjustment and optimization of particle size, making it ideal for applications that require a delicate feel or a thin coating.

flowology, usually in water-based coating systems, silicon dioxide anti-lighting powder absorbs the adhesive thickeners in the system (the unshielded silane alcohol group on the surface of the light-killing powder is the cause of strong interaction between silicon dioxide and polyurethane thickeners in the water-based system), thus reducing the consistency of the component thickeners.
Figure 4. The special reprocessing of the connected thickener
ACEMATT®3400 in the unshielded
silane alcohol-based group adsorption system on the surface of the anti-light powder
has caused the shielding of the silane-based group to prevent the adsorption of the connected thickener in the water-based coating system, thus ensuring the viscosity stability of the water-based coating system.
