coatings organic bentonite suspension

coatings organic bentonite suspension : Our most direct recommendation is to apply organoclay bentonite to matte paint, can be used with matting powder, at present organic clay bentonite and matting powder are our main products, then when you use organiclay bentonite to matte paint, it is the most direct solution to the matte system suspension stability problems. At the same time organophilic clay bentonite, in matte paint has a special application value. In the anti-sinking, suspension, anti-layering at the same time, can ensure that the matte effect is not affected.

Traditional organo bentonite, in the matte coating after 6 months will appear delamination, the probability of about 32%, and gloss deviation, will make each batch of color difference, while the thixotropic imbalance will also trigger construction difficulties, or spraying poor atomization.

The most special value of organoclay bentonite lies in the cation exchange capacity which determines the effect of directional arrangement of matte powder. Another characteristic of organic bentonite is low polarity, reducing the amount of matting agent, it has a better economic value, and in the layered structure provides three-dimensional mesh support, which makes organic bentonite adsorption capacity is also greatly improved.

Matte paint precipitation delamination problem is because the density of matting powder is greater than the resin system, we chose the solution is to use organic clay bentonite to modify, such as our CP-38 pre-gel process to enhance the thixotropic index to reach between 3.8 ~ 4.2 ah, the thixotropic index of the traditional organobentonite is 2.5 ~ 3.0.

We want to solve the matte paint gloss is not uniform then, the most important thing is in the organic bentonite, in the use of the choice of the amount to add, we recommend that you use between 0.8 ~ 1.2, the matting efficiency is optimal, and then choose a polar activator, preferably non-ionic, which will not affect the matte powder dispersion. High-temperature storage stability, 60 ℃ in 30 days of testing, the rate of change of brightness after storage is less than 8%, while the industry standard is less than or equal to 15%, so this point our organic bentonite clay is also greatly outperformed the industry standard.

Over the past 20 years, we will be used in Southeast Asia’s organophilic clay bentonite in the production of wood paint coatings, because Southeast Asia’s summer temperatures are very high, especially easy to precipitate clumps in transportation, and then use our organic bentonite heat-resistant, in the 40 ℃ environment, the viscosity stability increased by 300%, the customer’s complaint rate is also greatly reduced. We Once we start the cooperation, our engineers will carry out 1 to 1 technical support, and provide free samples for you to test.
