• Modified cycloaliphatic amine from IPDA. With a low viscosity it is suitable for low VOC coatings, provides fast cure rate, short pot life even in low temperature areas. Good weather/moisture and chemical resistance, weatherability, low blush, water spotting etc. Low yellowing floor systems ad it is recommended to be sued with ChemRes 800.
  • Such products are best in class solutions for long durability bonding under static or dynamic loads as. Siliconized epoxy resins can be prepared by the reaction of an amine-terminated silicone resin with a novolak-type epoxy resin. It is supplied in a cartridge with an in-line mixer tip and is designed for application using a geared sealant gun.
  • secondary, and tertiary amines, in which one, two, and three hydrogen molecule(s) of ammonia (NH3) have been substituted for hydrocarbon, respectively. Amines are called monoamine, diamine, tri-amine, or polyamine according to the number of amines in one molecule. Amines are classified into aliphatic, alicyclic (Three Bond 2106), and aromatic ...
  • 1) Amine-Epoxy Addition Reactions. Polyamines are the most common crosslinking agents for diepoxides such as diglycidyl ether of bisphenol A (DGEBA). Depending on the substituents, the amines can be divided into three main groups: aliphatic, cycloaliphatic and aromatic amines.
  • Apr 28, 2011 · As it is generally known, the epoxy-amine reaction is catalyzed by the presence of hydroxyl groups in the reagent’s structure, or introduced with other compounds, e.g., water, alcohol, or moisture. This allowed initiation and acceleration of the epoxy-amine cure process due to the formation of hydrogen-bonding groups [11, 12]. Moreover, based ...
  • CTP Egypt S.A.E. is a customer focused industrial company, founded in Egypt in 1992. It has provided its customers with a variety of epoxy hardeners and modified resins, catalysts and additives of proven and consistent quality for more than 28 years.
  • The effect of amine structure and amine to carbonate ratio on polyurethane structure and mechanical, physical, and swelling properties was stud-ied. m-xylylene diamine (m-XDA), p-xylylene diamine (p-XDA), and isophorone diamine were used as the reactants, with amine to carbonate ratios of 0.5 : 1, 1 : 1, and 1 : 2.
  • Nov 30, 2018 · Understanding mechanisms of cycloaliphatic epoxy resin curing with anhydride is important for the preparation of new thermosetting polymer materials. In this paper, the curing of commercial epoxy monomer 4-epoxycyclohexylmethyl-3,4-epoxycyclohexane-carboxylate ERL-4221 with 4-methylhexahydrophthalic anhydride in the absence of catalyst was studied by two complementary methods: Fourier ...

Cycloaliphatic amines will also produce epoxy cured coatings with better heat and chemical resistance, and improved mechanical properties. Secondary amines are lesser known than their primary amine types. These amines typically are slower to react than the primary aliphatic amine; and can be used to modify and slow the gelation process.
Ancamine® K54 by Evonik is a crosslinker based on 2,4,6-tris (dimethylaminomethyl) phenol. It is an efficient tertiary amine activator for epoxy resins cured with a wide variety of hardener types including polysulphides, polymercaptans, aliphatic & cycloaliphatic amines, polyamides, amidoamines, dicyandiamide and anhydrides.

EPALLOY 5000 is the diepoxide of the cycloapliphatic alcohol, hydrogenated Bisphenol A. Due to its saturated ring structure, this resin is expected to find utility in applications requiring resistance to ultraviolet light exposure. Formulations based on standard DGEBA resins usually do not perform well in this environment.
Amine type will alter both the processing properties (viscosity, reactivity) and the final properties (mechanical, temperature and heat resistance) of the cured copolymer network. Thus amine structure is normally selected according to the application. Reactivity is broadly in the order aliphatic amines > cycloaliphatic amines > aromatic amines.
