Paraformaldehyde is a polymer of formaldehyde with the chemical formula (CH2O)n, where n is typically in the range of 8 to 100. It is a white, crystalline solid composed of small, polymeric formaldehyde units. Paraformaldehyde is commonly used as a solid form of formaldehyde, and it has various applications in different fields. Form and Structure: Paraformaldehyde is a low-molecular-weight polymer of formaldehyde, consisting of repeating CH2O units. It is often produced in the form of white, crystalline granules or as a powder. Uses: Fixative in Histology: Paraformaldehyde is commonly used in histology and pathology laboratories as a fixative for preserving biological specimens for microscopic analysis. Disinfectant: It has disinfectant properties and can be used for sterilizing equipment. Crosslinking Agent: Paraformaldehyde is used in the crosslinking of proteins, peptides, and nucleic acids in molecular biology applications. Chemical Synthesis: It serves as a source of formaldehyde in various chemical reactions and syntheses. Handling and Safety: Paraformaldehyde should be handled with care, and precautions should be taken to avoid inhalation, skin contact, or ingestion. When paraformaldehyde is heated, it releases formaldehyde gas, which is a strong irritant. Adequate ventilation and protective equipment should be used when working with paraformaldehyde. Dissolution: To use paraformaldehyde as a fixative or in other applications, it is typically dissolved in water to generate a formaldehyde solution. Storage: Paraformaldehyde should be stored in a cool, dry place away from heat sources and incompatible materials.
Urea formaldehyde is a type of thermosetting resin that is produced by the reaction of urea and formaldehyde. This resin is commonly used in the production of adhesives, particularly for wood products such as particleboard, medium-density fiberboard (MDF), and plywood. The resin provides excellent bonding properties and is valued for its water resistance and durability. Urea Formaldehyde Concentrate (UFC 85) is a clear and viscous liquid, composed of formaldehyde, urea and water. It provides high concentration of formaldehyde commercially available in an easy-to-use form.
Urea Formaldehyde Concentrate (UFC 65) is a clear and viscous liquid, composed of formaldehyde, urea and water. It provides high concentration of formaldehyde commercially available in an easy-to-use form. Applications It is used in production of aminoplast resins such as urea formaldehyde adhesives, UF and MUF impregnation resins. It is used as anti-caking agent in the process of urea production.
