Non-Volatile, Wt. Diluents | Accelerators | Adhesion Promoters Specialty Resins | Additives Blushing occurs when moisture and carbon dioxide are present in sufficient amounts to react with the amine curative in an epoxy coating formulation. Nonylphenol and nonylphenol ethoxylates are only used as components of household detergents outside of Europe. The structure of the amine-containing organic compound and the number and type of amine groups in the compound is what determine the rate of cross linking and the coating's properties. These compounds are also precursors to the commercially important non-ionic surfactants alkylphenol ethoxylates and nonylphenol ethoxylates, which are used in detergents, paints, pesticides, personal care products, and plastics. In epoxy formulations, the active hydrogen of the amine is what reacts with the epoxide group of the resin. We believe that nonylphenol posses health hazards and compromises safety of resin art enthusiasts and epoxy applicators, so we formulated our products without it. NP is persistent in the aquatic environment, moderately bioaccumulative, and extremely toxic to aquatic organisms. Dec 9, 2021 · An active area of technology development is the design of improved epoxy/amine binder systems for low temperature cure coatings. NONYLPHENOL prevents resinification of the polymer during manufacturing and storage. 4- nonylphenol is an estrogenic endocrine active chemical that is a derivative from ethoxylated alkylphenol, a non-ionic surfactant present in pesticide formulation as adjuvant and is known to contaminate food and drinking water. Sep 1, 2017 · Benzyl alcohol (BA) and nonylphenol (NP) have long been used as plasticizers in epoxy thermoset formulations. A high-purity cardanol, 3-pentadeca-dienyl-phenol, derived from the bio-oil CNSL has been employed to replace nonyl phenol (NP) in various applications, including isocyanate blocking. Environmental concerns about using NPEs led the EPA to publish in 2010 a “Nonylphenol (NP) and Nonylphenol Ethoxylates (NPE) Action Plan. The theoretical molecular weight is 220, the theoretical hydroxyl number is 250, and the appearance is clear liquid. Oct 16, 2020 · Cashew nutshell liquid (CNSL) is a non-edible, bio-based material commonly used as a building block for various resins, hardeners, and modifiers in the adhesives, coatings, and composites industries. This blog post explains our reasoning behind our decision. . They are commonly added to amine hardeners to lower the viscosity and increase the reactivity of the thermoset formulations.
