2. Description of the Related Art Epoxy resin compositions have excellent electrical performance and adhesive strength, and are therefore used in various applications in the electric and electronic fields. It is known that the epoxy resin composition uses various curing agents at the time of curing, and that the performance of the cured product greatly varies depending on the type of the curing agent, and the curing agent is properly used depending on the application. For example, in the use of adhesives and laminates, amine-based curing agents are used because adhesion is the most important, and in casting applications, acid anhydrides are used from the viewpoint of electrical performance and low viscosity. Phenolic curing agents are used for sealing materials from the viewpoint of water resistance.

Conventionally, amines and acid anhydrides have been known as curing agents for liquid epoxy resin compositions such as solventless adhesives, sealing materials for electric and electronic parts, paints and the like. When a phenol-based curing agent is used, a phenol novolac resin is generally used, and the liquid epoxy resin composition has a large molecular weight and the addition amount of the phenol novolac resin curing agent to the epoxy resin is 50 PHR or more, which is large. The viscosity of is so high that it cannot be put to practical use. However, in terms of the balance of physical properties such as adhesiveness, water resistance, and electrical performance, the phenolic curing agent is the most excellent curing agent. That is, since it is difficult to liquefy, phenolic curing agents can generally be used only for solid molding materials. Amine-based and acid anhydride-based curing agents are easy to liquefy, but have the following problems. That is, when an amine-based curing agent is used, the hygroscopicity is high because a tertiary amine structure exists in the crosslinked structure of the cured product. When an acid anhydride-based curing agent is used, long-term water resistance is poor because the ester structure in the crosslinked structure of the cured product is easily chemically hydrolyzed, and the acid anhydride group of the curing agent and the epoxy resin The cured product is inferior in adhesiveness because the alcoholic hydroxyl group that contributes to adhesion is less likely to be by-produced by the reaction with the epoxy group.

e Automated Bonding) is being replaced. As a conventional liquid encapsulating material, an epoxy resin composition using an amine-based or acid anhydride-based curing agent is predominant because of its limited viscosity. However, the liquid encapsulant composed of the epoxy resin composition using the amine-based or acid anhydride-based curing agent is more than the transfer molding material composed of the epoxy resin composition using the phenol novolac resin curing agent described above. Poor overall reliability. Therefore, it is strongly desired to improve the reliability of the liquid sealing material. Therefore, in order to compensate for the drawback of high viscosity of the epoxy resin composition using a phenolic curing agent, the use of a solvent,
Although the handling of the liquid encapsulating material has been facilitated by using it together with an amine-based curing agent or an acid anhydride-based curing agent, the liquid sealing material has not yet reached a satisfactory stage.

Comparative Examples 1 to 9 Bisphenol A (reagent) which is a non-allylated compound of Compound A
Is referred to as compound a. Regarding Comparative Examples 1 to 7,
In Examples 1 to 7, compound A as a curing agent was used.
Epoxy resin compositions and curing were carried out in the same manner as in Examples 1 to 7 except that compounds a to compound g, which are non-allylated compounds of compounds A to G, were used instead of compound G, respectively. After obtaining the product, the viscosity of the epoxy resin composition at 25 ° C. was measured and the cured product was subjected to PCT treatment. In Comparative Example 8, phenol novolac (PSM6200: manufactured by Gunei Chemical Co., Ltd.) was used as a curing agent, and Comparative Example 9 was used.
About Example 1 to Example 7 except that an acid anhydride (B-650: manufactured by Dainippon Ink and Chemicals, Inc.) was used as a curing agent in a composition expressed in parts by weight for each compounding amount shown in Table 3. In the same manner as above, an epoxy resin composition and a cured product were obtained, the viscosity of the epoxy resin composition at 25 ° C. was measured, and the cured product was subjected to PCT treatment. The results are shown in Table 3.

From the results shown in Tables 2 and 3, the viscosities of the epoxy resin compositions of Comparative Examples 1 to 9 at 25 ° C. were 1 except for the epoxy resin compositions of Comparative Example 9.
It is a viscous material or solid that exceeds 10,000 poise (P). Comparative Example 9 is not possible because the cured product is dissolved and tacky after PCT treatment. On the other hand, in Examples 1 to 12, the viscosity of the liquid epoxy resin composition at 25 ° C. was 30
P to 7,000 P, most of them have low viscosity and are easy to handle, and are suitable for forming a resin sealing layer by spot sealing, and maintain a stable cured product even under the severe condition of PCT treatment. It was confirmed that the liquid epoxy resin composition was able to give a highly reliable cured product having excellent moisture resistance and heat resistance.
