Colophony of epoxy resin, phenolic aldehyde and colophony of not saturated polyester are called 3 big general-purpose colophony of hot solid sex. They are the dosage in colophony of hot solid sex the variety with big, wide application. Distinctive annulus oxygen is contained in epoxy resin base, and light base, ether bolts wait for active radical group and polar group, have a lot of superior performance consequently. With other heat photograph of solid sex colophony is compared, the sort of epoxy resin and brand are much, function each different. The sort of agent of epoxy resin solidify is more, wait plus numerous accelerant, modifier, additive, can have varied combination and matched stack. Can acquire various property thereby exceedingly good, the system of annulus oxygen solidify that provides distinguishing feature each and condensate. Can suit almost and satisfy the requirement of all sorts of distinct performance characteristics and technical properties. Colophony of sex of other heat solid can not compare this. 1, the function characteristic of epoxy resin and its condensate

(1) mechanical performance is high. Epoxy resin has very powerful cohesive force, molecular structure is compact, so colophony of its phenolic aldehyde of mechanical function prep above is mixed not saturated polyester general-purpose colophony of hot solid sex. (2) stick receive performance exceedingly good. The active in system of epoxy resin solidify huge annulus oxygen base, the polarity group such as hydroxyl and ether key, amine key, ester key gifts annulus oxygen condensate with extremely tall stick receive strength. Have the mechanical property such as very high cohesion intensity plus it, accordingly its stick receive performance particularly strong, can use as structural rubber. (3) solidify shrinkage is small. It is 1 ％ ～ commonly 2 ％ . It is one of assortment with small shrinkage of the solidify in colophony of hot solid sex (phenolic aldehyde colophony is 8 ％ ～ 10 ％ ; Colophony of not saturated polyester is 4 ％ ～ 6 ％ ; Organic silicone is 4 ％ ～ 8 ％ ) . The line bilges coefficient is very small also, it is 6×10-5/ ℃ commonly. Its product measure is so stable, internal stress is little, not easy craze. (4) craft sex is good. Epoxy resin basically does not produce small element volatile when solidify, low pressure shapes or can contact so pressure shape. The flexibility that the recipe designs is very big, can devise the recipe that fits all sorts of craft sex requirements. (5) electric performance is good. It is one of breed with good performance of report of intermediary of colophony of hot solid sex. (6) stability is good. Disagreement the epoxy resin of the impurity such as alkaline, salt deteriorates not easily. As long as reserve is appropriate (sealed, not be affected with damp be affected with damp, do not encounter high temperature) , its keep in storage period for 1 year. Exceed period hind if certificate of proof still can be used. Annulus oxygen condensate has excellent chemical stability. The function excel that a variety of medium such as its alkali resistance, acerbity, salt corrode is not saturated the heat such as polyester colophony, phenolic aldehyde colophony originallies sexual colophony. (7) the hear resistance of annulus oxygen condensate is 80 ～ commonly 100 ℃ . The heat-resisting breed of epoxy resin can amount to 200 ℃ or taller. (8) lie in heat in sexual colophony, the integral performance of epoxy resin and its condensate is good. 2, the applied characteristic of epoxy resin

(1) have huge recipe to design flexibility and diversity. Can press distinct performance characteristics and technical properties demand, the design gives the beautiful recipe with very strong specific aim. This is the one big characteristic in epoxy resin application and advantage. But every beautiful recipe has certain suitable scope (conditional) , not be to be below any craft conditions and aleatoric use condition appropriate is used. Do not have the beautiful recipe of “ all-purpose ” that is to say. Need fibrous root occupies different condition, the design gives different beautiful recipe. Because the solidify principle of the system of epoxy resin solidify of different recipe is not identical, so the solidify course of epoxy resin, namely solidify craft condition is affected to the structure of annulus oxygen condensate and function great. Identical recipe changes the function of product of the earning below craft condition to be able to have exceedingly big difference in different solid. Making design of beautiful material recipe and technology design correctly so is the key of technology of epoxy resin application, also be technical secret place. Can be produced and should develop the annulus oxygen material that wants performance from personal place, must design corresponding special recipe to reach its to shape craft condition. Accordingly, the structure that must understand deep and masters epoxy resin and its solidify agent, modifier to wait and function, reaction mechanism between them and the influence that reach function to structure of annulus oxygen condensate. Such ability design the with facility in be being designed with craft in material recipe, apply freely, obtain beautiful program, production and development give the annulus oxygen stuff with function beautiful, low cost and product. (2) system of different epoxy resin solidify can be in respectively microtherm, room temperature, medium lukewarm or high temperature solidify, can be even in damp surface in water solidify, can fast solidify, also can slow solidify, the adaptability that so it asks to construction and workmanship is very strong. Epoxy resin but low pressure shapes or osculatory pressing shapes, because this can be reduced,to shaping equipment is mixed the requirement of the mould, reduce investment, reduce cost. (3) be in 3 big general-purpose in colophony of hot solid sex, the price on the high side of epoxy resin, be affected certainly thereby on application. But, because its performance is superior, basically use at tall to performance characteristics requirement circumstance so, ask to integral performance especially tall domain.
