1. Description: It is the raw material for making thermosetting resin, light curing epoxy resin coating, oil resistant coating and drying coating. Its copolymer emulsion is used for fiber finishing, fabric, leather and paper coating. Also used as wood, metal and other adhesives. 2. Typical recipes Used as crosslinked monomer in acrylic emulsion. The amount of carboxyl-containing acrylic emulsion pressure-sensitive adhesive is L % ~ 2% of the total monomer mass, and the initial adhesion will be greatly reduced if it exceeds 3%. For emulsion adhesives without carboxyl group, the general dosage is not more than 5%. The crosslinking reaction temperature of MMAM alone is high, generally 120 ~ 170�ºC, and the addition of protic catalyst can reduce the crosslinking temperature. Acrylic acid (AA) can both provide hydrogen protons and copolymerize with acrylates, so MMAM should be used as a composite crosslinking agent with AA at a dosage of 3:2. Cross-linking agent HA can replace N- hydroxymethyl acrylamide, and does not contain formaldehyde. 3. Application scope A. Can be used as crosslinking agent, widely used in fiber modified resin, processing dyes, plastic adhesives, soil stabilizers, etc. B. Used for fiber modification, resin processing, adhesives and paper, leather, metal surface treatment agent. Free samples 4. Storage and packaging A. All emulsions/additives are water-based and there is no risk of explosion when transported. B. This product can be packed in 25KG,50KG,200KG,1000KG plastic barrels. C.

Applications Applications DovaFR P4-red is as an ideal halogen-free Flame retardant in thermoplastic (e.g. polyamide) and thermosets (e.g. epoxy resins or polyurethanes) base on its high content of P. Phosphorus is the element with the most fire retardant effect among all elements so that it can efficiently obtain a fire retardant effect with small quantities. This makes it possible to minimize the degradation of the physical properties of the resin. In other industry, DovaFR P4-red is applied in fireworks, matches, organic synthesis, medicine, synthetic material, pesticide and et.
Product Description DovaFR P4-red is an allotrope of element. It is nontoxic, odorless and active chemically, though not highly. It is dark red, and unlike white phosphorus, is not phosphorescent. It has a variety of applications in industry, such as matches, fireworks and especially in Flame retardant. Benefits 1. DovaFR P4-red is a fine red or auburn amorphous powderwith high purity. 2. DovaFR P4-red is made of low arsenic Yellow phosphorus (P4 yellow), which makes product more purity than others. 3. DovaFR P4-red is applied in thermoplastics and thermosets as a very effective flame retardant (N-P based). 4. DovaFR P4-red is with excellent properties with its strictly standard.

Melamine formaldehyde resin is a type of thermosetting plastic that is formed by the polymerization of melamine and formaldehyde. This resin is commonly used in various applications, including laminates, coatings, adhesives, and molded products. When you refer to "Concentrated Melamine Formaldehyde Resin," it suggests a formulation with a higher concentration of the resin, which may be used in specific industrial processes. Composition: Melamine formaldehyde resin is typically produced by the reaction of melamine (a nitrogen-rich compound) and formaldehyde (a reactive aldehyde). The reaction results in a highly cross-linked polymer with excellent hardness, chemical resistance, and heat resistance. Properties: High Heat Resistance: Melamine formaldehyde resin exhibits high heat resistance, making it suitable for applications where exposure to elevated temperatures is a concern. Hardness and Durability: The resin imparts hardness and durability to the materials it is used in, making it valuable for products like laminates and molded items. Chemical Resistance: Melamine formaldehyde products are known for their resistance to chemicals and staining. Applications: Laminates: Melamine formaldehyde resin is commonly used as a coating for laminates, which are widely used in furniture, countertops, and decorative surfaces. Molded Products: It is used in the production of molded items, such as kitchenware, dinnerware, and electrical components. Adhesives: The resin is used in the formulation of adhesives for bonding wood and other materials. Concentration: The concentration of melamine formaldehyde resin can vary based on the specific formulation required for a given application. A concentrated form may be used to achieve specific performance characteristics or to facilitate easier handling and storage. Manufacturers and Suppliers: Different manufacturers may produce concentrated melamine formaldehyde resins with varying specifications. It's essential to consult with the specific manufacturer or supplier for detailed information about the product's formulation, recommended uses, and handling guidelines.
