  • what is the steel drum coating resin? take a look

    steel drum is one of the traditional containers, the application has a history of more than one hundred years, in today, the packaging technology changes with each passing day, the application of steel drum in some aspects has been partially replaced by plastic or composite, but because the steel has excellent comprehensive performance, and rich resources, so the steel packaging container still maintains vitality, the application form is more diverse. According to the surface coating composition

  • What are the requirements for adhesion promoters in the process of painting and gluing?

    In the process of surface treatment, the form is mainly concentrated in painting, electroplating and gluing. Different processes have different values or surface effects, but they also face many problems in the actual construction process. Poor surface treatment. Taking spray paint and glue as an example, it is reflected in the unqualified test of spray paint and the poor firmness between adhesive and degumming substrate and glue. The above problems are generally solved by applying primer adhesi

  • coating? Can the gloss of the coating be changed?

    For ordinary engineering applications, the gloss of the coating is generally maintained at a relatively moderate level, and the required gloss can be achieved by changing the surface state of the coating through simple physical and chemical methods; but for some special needs, when the coating is required to have high or low gloss, it must take corresponding technical measures to change the gloss of the coating.

  • styrene-acrylic emulsion? What is the determination method?

    emulsion particles aggregate with each other to form a film is the MFT of the emulsion. When the ambient temperature is lower than this temperature, the emulsion particles cannot be aggregated into a film and become powder or chips. In the polymer emulsion, the polymer is dispersed in water as solid spheres, each of which is composed of several polymer macromolecules. To make the polymer film in the emulsion, the spheres should coalesce and fuse with each other to form a continuous transparent f

  • Talking about the Use Method and Principle Application of pp Treatment Agent [Dry Goods]]

    PP treatment agent is hydroxy chlorinated polypropylene copolymer, which is applied to PP material, modified PP material, miscellaneous material and other surface spraying processes. It can modify the wettability and surface adhesion of PP substrate and combine with each other by forming a layer of film between the substrate and paint. Promote the interlayer adhesion between paint and pp material to form a firm coating, so as to solve the poor adhesion caused by spraying paint and other undesira

  • What are the commonly used international standards for the determination of VOC content?

    At present, the international general definition of VOC in coating products refers to any organic liquid or solid that can evaporate on its own under the normal temperature and pressure of the atmosphere in contact with the coating product. Generally, any organic compound with a boiling point of no more than 250 ° C at atmospheric pressure is defined as volatile organic compound (VOC).
