What are the fire resistance properties of epoxy resin?5 answersEpoxy resin (EP) can be modified to enhance its fire resistance properties. Various flame retardants have been synthesized and incorporated into EP to improve its fire resistance. The addition of reactive phosphaphenanthrene aromatic ether diamine (PBAH) flame retardant resulted in improved heat stability, outstanding fire resistance with an improvement in limiting oxygen index (LOI) value, and a V-0 rating in UL-94 test. The incorporation of a nitrogen-rich DOPO-based derivative (FATP) also reduced the fire hazard of EP, achieving a UL-94 V-0 rating and an LOI value of 35%. A multifunctional nanoparticle (Cu2[email protected]) conferred great fire resistance with an LOI of 34.7% and reduced peak heat release rate (PHRR) by 56.3%. A heterocyclic compound (BDP) facilitated the curing reaction of EP and achieved a V-0 classification with an LOI of 35.2%. A phosphorus-containing melamine cyanurate derivative (P-MCA) flame retardant improved the fire resistance of EP, achieving a V-0 level in UL-94.
What is resin?5 answersResin is a versatile material that can be derived from various sources such as plants, polymers, and compounds. It is typically a noncrystalline solid or semi-solid substance that can be transparent or translucent, and ranges in color from yellowish to brown. Natural resins are produced by plants and are soluble in organic liquids but not in water. They can be in the form of terpenes with volatile oils, resinous substances containing benzoic acid or cinnamic acid, or mixtures of polysaccharides. Resins are also derived from polymers and compounds, such as fluorine-containing polymers, and are used for various purposes including as film formers, binders, and mold materials. Resin materials can have different properties depending on their composition, such as high strength and dimensional stability.
What is the characteristics of resins for coatings?3 answersResins for coatings have various characteristics depending on their composition. Some resins contain rubber-reinforced vinyl-based resin and olefin-based resin modified by a polar functional group, which enhances their properties. Other resins may contain cyclic ether group-containing polymers and polycarboxylic acids or polycarboxylic acid anhydrides, which provide anti-fogging and anti-dirt properties. Additionally, polyacrylate resins containing fluoroalkyl groups are used to prepare powder clear coatings, offering properties such as gloss, adhesion, scratch resistance, and hydrophobicity. Resin compositions with a branched structure, polyisocyanate, and reactive inorganic particles can provide excellent appearance, wear resistance, and hardness in coating films. Furthermore, a coating resin solution with a hydroxyl acrylic resin and an amino resin can form a protective coating with good weather resistance, surface hardness, solvent-wiping resistance, and tensile strength.
What are protein A resins?2 answersProtein A resins are commonly used for capturing monoclonal antibodies from cell culture broths. These resins are expensive, so it is important to reuse them for multiple cycles to make the process economically feasible. However, resin reuse leads to fouling, which affects the binding and mass transfer characteristics of the resin. Protein A resins can also be used to fabricate 3D printed structures from biocompatible proteins. By forming a photoreactive proteinaceous resin and using patterned light application, biocompatible structures can be printed and cured from the resin. Additionally, protein-based films can be made from proteins for packaging materials. These films have the advantage of being biodegradable and can be sourced from renewable sources or by-products of the food and agriculture industries. Finally, a resin-based composition has been developed for treating periodontal disease, which includes a compound with an acidic group and a polymerizable group, a filler, and a protein that induces regeneration/bonding of periodontal tissue.
