ZSM-5B
ZSM-5 molecular sieve is a high-silicon zeolite, its Si/Al ratio can be as high as 1000 or more, and this kind of molecular sieve also shows the characteristics of hydrophobic. Their structure is characterized by the crystal silicaluminate composed of 10-element pores. Its basic structural unit is composed of eight five-membered rings, no cage cavity, only channels. ZSM-5 has two sets of intersecting channels, one straight through and the other perpendicular to each other. The channel is elliptical and its window diameter is 0.55-0.60nm. Due to the similar reaction space and the shape of the inlet and outlet, this kind of molecular sieve has a shape selection effect on the reactants and products, coupled with the homogeneity of its structure and hydrothermal stability, making it a good selective catalyst raw material.
ZSM-5 molecular sieve catalyst is widely used in petrochemical processing industry. It can be used as an auxiliary agent in the process of fluid catalytic cracking, which can increase propylene and liquefied gas production and improve the octane number of gasoline. In addition, it can be used for the production of ethylbenzene, p-xylene, phenol, pyridine, etc. -

YIHOO NOR152
Chemical name：Ethanol, 2-amino, reaction products with cyclohexane and peroxidized N-butyl-2,2,6,6-tetramethyl-4-piperidinamine-2,4,6-trichloro-1,3,5-triazine reaction productsCAS number：191743-75-6Appearance：Off-white powderApplication：Migration of the light stabilizer leads to depletion and subsequent degradation of the coating. Thisphenomenon is particularly obvious on plastic coatings, but it can also occur on varnishes or “wet on wet” coatings used for primers. By means of primary hydroxyl, NOR 152 can bind to chemical components in many coatings,such as melamine and isocyanate crosslinkers, fixing them in the paint and thus preventing migration. NOR 152 has excellent compatibility and long performance in polar, highly cross-linked coating systems where traditional hindered amine radical catchers may not be compatible. These coatings include polyester or acrylic carbamate, as well as highly cross-linked polyester or acrylic melamine systems. Due to its low alkaline properties, NOR 152 is also effective in thermosetting systems,such as traditional acid-catalyzed automotive and coil coatings, as well as thermoplastic acrylics and oxy-dried alkyd resins used in industrial/decorative paints and varnishes.The optimal dosage of NOR 152 to achieve the desired effect should be selected according to the experimental results. The following dosage is based on resin solid content:Paint system: based on 1-2% of resin solids. In varnishes or color paints that are prone to fading or discoloration or on photosensitive substrates, very good results can be obtained by matching 1-3% UV absorbers. The pure solid product is added to the polyhydroxyl part of a two-component polyurethane resin or to a one-component coating. Mix well before use. This product can be pre-dissolved in a solvent and then added to the coating formulation.
