Find sorbitol polyglycidyl ether and related products for scientific research at MilliporeSigma. 17/06/ · Sorbitol polyglycidyl ether (SPE) was cured with citric acid (CA), tartaric acid (TA), maleic acid (MA) and itaconic acid (IA) as biobased di- and tricarboxylic acids in the presence or absence of microfibrillated cellulose (MFC) to produce biobased epoxy nanocomposites or cured epoxy resins, respectively. For the curing systems of SPE/IA, the Author: Kaito Sugane, Tomoyuki Mishima, Mitsuhiro Shibata. Denacol EX is a sorbitol polyglycidyl ether. Its aliphatic epoxy backbone enables formulators to create coatings that are: Non-yellowing; Resistant to weathering; Low in color; The tetrafunctionality of Denacol EX increases the reactivity and crosslink density of formulations, resulting in coatings with: Faster cure speed.

Coating compositions containing a polyfunctional glycidyl ether of sorbitol cured at ambient temperature with polyamidoamine hardeners exhibit unexpectedly high resistance to loss of gloss when exposed to weathering conditions. The cured product also have good mechanical and chemical properties. Coatings of a polyfunctional glycidyl ether of sorbitol cured with polyamidoamine hardeners exhibit high resistance to loss of gloss when exposed in outdoor applications.

While cured epoxy resin systems based on bisphenol A and other aromatic polyols generally exhibit good mechanical properties, they show a relatively poor resistance to weathering in outdoor applications or upon exposure to ultraviolet light. Since such weathering problems are clearly understood to be related to the aromatic moieties in the bisphenol A epoxy resins, epoxy resins having no aromatic moieties have been made.

Lee and Neville, Handbook of Epoxy Resins, McGraw-Hill, New York, , p describes such epoxy resins derived from aliphatic polyols. High molecular weight polyglycidyl ethers, prepared by the hydroformylation of oleyl alcohol and related unsaturated alkenols followed by glycidylation of the polyol formed, are described in U. Such glycidyl ethers are stated to be curable by a host of hardener types, i.

While aliphatic epoxy resins are expected to exhibit better weather-resistance than aromatic epoxy resins, they are usually deficient in such properties as a combination of hardness and flexibility toughness and in chemical, solvent and moisture resistance as is taught in U. Aliphatic glycidyl ethers have been used in cold-curable, solvent-free coating compositions using cycloaliphatic polyamines as curing agents to give cured coatings with high resistance to organic solvents as described by J.

Bersier et al, FATIPEC, , Similar coating compositions were tested for color and gloss retention in outdoor weathering applications. Such coatings had excellent resistance to discoloration, but showed a high loss of gloss after only a few months of outdoor exposure as is described by T.

Your report on Product s , Selling Lead s will be sent to EC21 Administrators once submitted. Then, Administrators will investigate and then take appropriate actions. Glyether Product EJ epoxy resin is an aliphatic multifunctional epoxy resin. EJ epoxy resin will impart both higher reactivity and crosslink density to epoxy resin formulations. Polyglycidyl ether type EJ epoxy resin is used to modify standard epoxy resin formulations to improve flexibility.

This resin is compatible with both bisphenol-A and other epoxy resins, adding flexibility, better impact and improved elongation to end products. This epoxy resin functionality permits them to cross-link with hardeners and become part of the cured system. Additionally, Glyether Product EJ can be used to crosslink acid functional polyurethane and acrylic resins for improved chemical resistance in light stable coatings. Glyether Product EJ resin is ideal for adhesives, laminate, water soluble additives and wet lay-up applications.

Glyether Product EJ resin can be cured with various hardeners through the epoxide groups. Resulting in highly cross-linked thermoset polymers having good mechanical properties, good resistance to chemical and solvent resistance.

Materials Basel, Switzerland , 27 Apr , 10 5 DOI: Carbon fibre reinforced flame-retarded bioepoxy composites were prepared from commercially available sorbitol polyglycidyl ether SPE cured with cycloaliphatic amine hardener. The fire performance of the composites was investigated by limiting oxygen index LOI , UL tests, and mass loss calorimetry.

The effect of FRs on the glass transition temperature, and storage modulus was evaluated by dynamic mechanical analysis DMA , while the mechanical performance was investigated by tensile, bending, and interlaminar shear measurements, as well as by Charpy impact test. In formulations containing both FRs, the presence of RDP, acting mainly in gas phase, ensured balanced gas and solid-phase mechanism leading to best overall fire performance. APP advantageously compensated the plasticizing storage modulus and glass transition temperature decreasing effect of RDP in combined formulations; furthermore, it led to increased tensile strength and Charpy impact energy.

The need for the development of polymers originating from renewable resources is increasing with the decreasing amount of the mineral oil stock and with the spreading of environmental awareness. This tendency has emerged also in the polymer composite industry, including such demanding sectors as automotive and aircraft applications [ 1 ], where high performance thermosetting materials such as epoxy resins are applied.

Besides the environmental advantages, the partial or full replacement of polymer matrices and reinforcements by renewable ones can reduce the dependence on petrochemicals and eliminate the effect of their fluctuating price level. The use of natural fibres as reinforcement in bio-based matrices seems to be an obvious solution [ 2 ].
