Which kind of optical brightener can make the water-based sealant high in whiteness

The water-based sealant is mainly made of polymer water emulsion, rubber emulsion, water-soluble resin and water-based polymer materials as the main body, adding dispersant, stabilizer, defoamer, curing agent, titanium dioxide inorganic filler, etc., and is made by grinding. It is needed in construction and industrial fields. Sealant is an adhesive with a wide range of applications, which has the functions of anti-leakage, anti-vibration, anti-sound and heat insulation.
A part of the titanium dioxide should be added to the water-based sealant to cover and increase the whiteness of the product, but why add the water-based sealant optical brightener RQT-C-2? Because in the titanium dioxide process, especially the sulfuric acid titanium dioxide process, most of the operations are to remove impurities in the titanium dioxide, because the impurities seriously affect the application performance of the titanium dioxide, especially the whiteness. However, after various operations, there will still be many substances that affect the whiteness of titanium dioxide, so many manufacturers of water-based sealants still feel that the whiteness value of titanium dioxide is relatively low and the color is yellowish. In addition, the whitening principle of titanium dioxide is a physical covering type. When the whiteness reaches a fixed value, the whiteness will not increase. At this time, we need to use the water-based sealant optical brightener RQT-C-2 to complement the color optically. So that the effect can be achieved very well.
The water-based sealant fluorescent whitening agent RQT-C-2 emits visible blue fluorescence by absorbing invisible light. The sealant produced in this way has a very high grade, regardless of the whiteness, hue, and brightness. Therefore, many manufacturers will choose to add part of the water-based sealant whitener during production, and the amount of addition is basically maintained at 100-200 grams per ton of material. The specific amount of addition can be adjusted according to the requirements of the product.
If your water-based sealant also has yellowing, insufficient whiteness, and lack of brightness, you can add a part of the water-based sealant optical brightener RQT-C-2 to improve product quality.
