Description
Melamine Resin is a type of amino resin synthesized from melamine and formaldehyde. It is characterized by a thermosetting nature, being colorless, odorless, and resistant to organic solvents. Melamine Resin exhibits greater resistance to alkalies and acids compared to urea resins, and it possesses superior heat and color stability along with a harder texture. The resin formation initiates with the production of trimethylol melamine, which can further combine with similar molecules through condensation reactions, leading to chain growth and cross-linking. The polymerization process is influenced by pH, and heat is essential for curing. Melamine Resins are more water and heat-resistant than urea resins and can be found in various forms, such as water-soluble syrups or insoluble powders dispersible in water.
Uses
Used in Textile Industry:
Melamine Resin is used as a treatment for heavy fabrics, draperies, collars, and apparel, providing properties such as waterand oil-repellence and flame-retardancy, effective on both synthetic and natural fibers.
Used in Coatings and Varnishes:
Melamine Resin is utilized in coatings and varnishes due to its good adhesiveness, although its hardness necessitates combination with alcohol-modified urea-formaldehyde resins to achieve a balance of color, gloss, flexibility, and chemical resistance.
Used in Molding Plastics:
Melamine Resin serves as a molding plastic with applications in various industries, including the production of high-strength and dielectric materials, such as melamine-urea-formaldehyde resin with a tensile strength of 51 MPa and a dielectric strength per mil of 12.8×10^6 V/m.
Used in Adhesives:
Melamine-urea-formaldehyde resin with a lignin extender is employed as an adhesive for water-resistant plywood, showcasing its effectiveness in bonding and water-resistance.
Used in Laminating Fibrous Materials:
Phenol-modified melamine formaldehyde resin solution is applied in the lamination of fibrous materials, highlighting its role in creating strong and durable composites.
Used in Molding High-Gloss Buttons:
Highly translucent melamine formaldehyde resin is used for molding high-gloss buttons, demonstrating its versatility in producing aesthetically pleasing and functional items.
Used in Woolen Fabrics:
Methylol-melamine, created by alkylating melamine-formaldehyde resin with methyl alcohol, is used for shrink-proofing woolen fabrics, showcasing its ability to enhance fabric properties.
Used in Paint and Enamel Solvents:
Butylated melamine resins, formed by incorporating butyl or other alcohols during resin formation, are soluble in paint and enamel solvents, offering exceptional curing speed, hardness, wear resistance, and resistance to solvents, soaps, and foods.
Used in Water-Base Industrial and Automotive Finishes:
Melamine-acrylic resins, being water-soluble, are utilized in the formation of water-base industrial and automotive finishes, indicating their environmental compatibility and practical applications in various sectors.
Additionally, melamine resins are employed in applications such as increasing the wet strength of paper, textile treatment, leather processing, and for creating dinnerware and decorative plastic items, further demonstrating their diverse utility across industries.
Biochem/physiol Actions
This gene belongs to the subfamily of small cytokine CC genes. Cytokines are a family of secreted proteins involved in immunoregulatory and inflammatory processes. The CC cytokines are proteins characterized by two adjacent cysteines. The cytokine encoded by this gene displays chemotactic activity for resting CD4 or CD8 T cells and eosinophils. The product of this gene binds to chemokine receptors CCR3 and CCR10. This chemokine may play a role in the physiology of extracutaneous epithelial tissues, including diverse mucosal organs.

Check Digit Verification of cas no
The CAS Registry Mumber 9003-08-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 9003-08:
(6*9)+(5*0)+(4*0)+(3*3)+(2*0)+(1*8)=71
71 % 10 = 1
So 9003-08-1 is a valid CAS Registry Number.
