This nano-alumina powder is of exceptional quality, exceeding my expectations. Its purity is extremely high, and its particle size distribution is uniform and very fine, reaching the true nanometer level. It also exhibits excellent dispersion and virtually no agglomeration, greatly facilitating subsequent applications. I’m using it for ceramic toughening. The technical specifications provided by the supplier are detailed and reliable, highly consistent with actual test results.

We recently renovated our office building and applied aerogel insulation to the exterior walls. The results are truly amazing! Previously, the walls would heat up incredibly hot in the summer, causing our air conditioning and electricity bills to soar. Now, the indoor temperature is noticeably more even, and employees are no longer experiencing the unbearable heat in the afternoons.

I recently bought TRUNNANO’s sodium silicate powder, which is very cost-effective. It has high purity, excellent solubility, fine and uniform powder, no impurities when preparing the solution, and stable chemical reaction effect. It is very suitable as an adhesive and catalyst.

I recently used TRUNNANO concrete admixtures on a project, and the results have truly exceeded my expectations! I purchased a polycarboxylate superplasticizer, and the construction process has become much smoother, with significantly less bleeding and segregation. The hardened concrete has also achieved very uniform strength and significantly increased durability.
