EPOTUF Epoxy Resins & uring Agents
STRENGTHEN YOUR OATING PERFORMANE WITH EPOTUF Formulating coatings for marine, aerospace, industrial maintenance and flooring applications is a tough job made easier by using raw materials that provide tough performance. Reichhold s EPOTUF resins provide the epoxy coatings formulator with a broad selection of epoxy resins and curing agents. Epoxies are thermosetting resins that contain an oxirane or epoxide ring and form infusible, insoluble solids when crosslinked with amine or other types of curing agents. uring agent selection and conditions are key factors which determine the final properties of epoxy systems. Typically curing agents crosslink epoxy resins in one of two ways: by reacting with the epoxide group to become part of the final polymer network or by acting as a catalyst to promote homopolymerization of the resin. PERFORMANE Excellent adhesion MAJOR MARKETS Protective coatings Low shrinkage onstruction / civil engineering Excellent mechanical properties Structural adhesives Excellent solvent & chemical resistance omposites Good electrical properties Electronics / encapsulation EPOTUF EPOXY RESIN & URING AGENT MIX RATIO To achieve the optimum performance results from an epoxy / amine curing agent system, it is important to use the resin and curing agent in the appropriate stoichiometric mix ratio where calculations are based on the ratio of the reactive components. After testing the stoichiometric : ratio it may be necessary to vary the ratio of epoxy to amine depending on the application and desired physical properties. The table below highlights some general trends observed when excess amine or epoxy are used. Property Excess Amine Excess Epoxy Water Resistance Reduces Increases Heat Distortion Reduces Reduces Acid Resistance Reduces Increases Alkali Resistance No Effect No Effect Solvent Resistance Reduces Reduces Flexibility Increases Reduces To calculate the stoichiometric use ratio, the following information is needed: Amine Hydrogen Equivalent Weight (AHEW) of curing agent AHEW = Molecular Weight of Amine or 56,00 # of Amine Hydrogens (Amine Value) x (Average # H s per N) Epoxide Equivalent Weight (EEW) of epoxy resin ALULATING MIX RATIOS alculate the stoichiometric parts by weight of curing agent per 00 parts of epoxy resin (phr). phr = AHEW of uring Agent X 00 EEW of Epoxy Resin Example: EPOTUF 7-27 epoxy resin EEW = 200 EPOTUF 7-60 curing agent AHEW = 85 phr = 85 X 00 = 42.5 200 Therefore, 42.5 parts of EPOTUF 7-60 curing agent are needed to cure 00 parts of EPOTUF 7-27 epoxy resin for a : stoichiometric ratio. alculate the AHEW of a blend of curing agents. AHEW of uring Agent Blend = Total Weight of uring Agent Blend Weight A + Weight B Example: AHEW A AHEW B EPOTUF 7-27 epoxy resin is being used with a curing agent blend consisting of 80 parts EPOTUF 7-60 and 20 parts EPOTUF 7-65. EPOTUF 7-27 epoxy resin EEW = 200 EPOTUF 7-60 curing agent AHEW = 85 EPOTUF 7-65 curing agent AHEW = 74 AHEW of uring Agent Blend = 00 = 8 phr = 8 X 00 = 4.5 80 20 + 200 85 74 Therefore, 4.5 parts of curing agent blend are needed to cure 00 parts of EPOTUF 7-27 epoxy resin. alculate the EEW of a blend of epoxy resins. EEW of Epoxy Resin Blend = Total Weight of Epoxy Resin Blend Weight A + Weight B Example: EEW A EEW B 90 parts of EPOTUF 7-40 epoxy resin is being blended with 0 parts of EPOTUF 7-05 reactive diluent to reduce the viscosity. This epoxy resin blend will be reacted with EPOTUF 7-70 curing agent. EPOTUF 7-40 epoxy resin EEW = 85 EPOTUF 7-05 epoxy resin EEW = 675 EPOTUF 7-70 curing agent AHEW = 9 EEW of Epoxy Resin Blend = 00 = 200 phr = 9 X 00 = 47 90 + 0 200 85 675 Therefore, 47 parts of EPOTUF 7-70 curing agent are needed to cure 00 parts of the epoxy resin blend.
