It is not limited. The addition amount is 0.5 to 5 parts by weight with respect to 100 parts by weight of the total amount of the polymer (I) and the polymer (II). When it is less than 0.5 weight, the storage stability is deteriorated. Moreover, it is because it will become easy to adhere | attach to glass when it is more than 5 weight part.

  Other additives include thixotropic agents, phenolic resins and epoxy resins, pigments, various stabilizers, anti-aging agents, ultraviolet absorbers, photocurable compounds for surface modification purposes such as oligoester acrylates, A solvent for adjusting the viscosity can also be added. However, no tackifier such as various silane coupling agents generally used in moisture curable resin compositions is added.

  The resin composition of the present invention may further contain a component that imparts a visual effect. By giving a visual effect, the degree of freedom of decoration can be further increased as compared with the case of only the shape. Examples of the component that imparts a visual effect include a colorant, a phosphorescent agent, a bright inorganic pigment, a fluorescent pigment, and a cholesteric liquid crystal pigment that changes color. These visual effect imparting components can be used alone or in combination. Since the resin composition of the present invention is rapidly cured and has good storage stability, these components can be retained for a long period of time, and the effects of these components can be sufficiently exhibited.

  In addition, the fat composition of the present invention is a pressure sensitive adhesive sheet or pressure sensitive adhesive tape in which a synthetic resin film such as polyester, polyethylene, polypropylene, polystyrene, polyamide or the like is used as a support and the resin composition of the present invention is applied on one or both sides thereof.

Next, the atmosphere in the reactor was replaced with nitrogen gas, and while maintaining the internal temperature at 50 ° C., 3-isocyanatopropyltrimethoxysilane (purity 95%) was added so that NCO / OH was 0.97. did. Subsequently, the internal temperature was maintained at 80 ° C. for 8 hours, the polymer (P) and 3-isocyanatopropyltrimethoxysilane were subjected to urethanation reaction, and a polymer having a trimethoxysilyl group introduced into 90% of the molecular chain terminals was obtained. Combined C was obtained.

  Here, the introduction rate of hydrolyzable silicon in the polymer was determined from 1H-NMR analysis.

Examples 1-4 and Comparative Examples 1-4.
Polymer A was used as polymer (I), and polymers B and C were used as polymer (II). To these polymers were added polypropylene glycol as a plasticizer and silica from which moisture was removed by heating and drying as a filler, and the mixture was stirred and mixed using a planetary stirrer (manufactured by Kurabo Industries). After the temperature of the obtained mixture was lowered to room temperature, pyrethrin as a pest repellent, a silane compound as a dehydrating agent and dibutyltin bis (acetylacetonate) [(n-C ₄ H ₉ ) ₂ Sn (acac) ₂ as a curing catalyst The mixture was stirred and mixed to obtain a moisture curable resin composition. Table 1 shows the compositions of the resin compositions of Examples 1 to 4 and Comparative Examples 1 to 4.

(Evaluation)
(1) Test for peelability against glass A moisture curable resin composition was placed on a glass plate specified in JIS R 3202 at a temperature of 23 ° C. and a humidity of 55%, followed by curing for 3 days. A simple adhesion test (based on the method described in the handbook for building sealants published by the Japan Sealant Industry Association) was conducted, and the peelability from glass was evaluated using the following evaluation criteria.
○: The resin composition can be easily peeled off from the glass.
X: Part of the resin composition remains attached to the glass.

(2) Storage stability test The moisture curable resin composition filled in the cartridge container was stored in an oven at a temperature of 50 ° C. and a humidity of 80% for 7 days, and then extruded to determine whether or not the appearance had changed. Time). The following evaluation criteria were used.
○: There is no change in appearance, and tack-free time does not change more than twice.
X: The tack-free time exceeds twice.

(3) Repellency test The repellency was evaluated by the filter paper contact repellency test method. That is, Toyo filter paper No. 9 having a diameter of 9 cm. A moisture curable resin composition was cast on 5A so as to have a thickness of 2 mm and air-dried for 24 hours. This was cut into two semicircles, one of which was placed on a glass plate in the same way as an untreated filter paper cut into a semicircular shape. A glass ring was placed. 10 ants are released as test worms, and after 180 minutes, the number of individuals present in the untreated group (untreated filter paper) and the treated group (treated filter paper) is counted, and the repellent rate is calculated by the following formula. did.
Repelling rate (%) = (number of untreated ward individuals−number of treated ward individuals) / number of untreated ward individuals × 100
The evaluation criteria for repellency are as follows.
○: Repelling rate is 50% or more.
×: Repelling rate is less than 50%

(Evaluation results)
Table 2 shows the evaluation results of Examples 1 to 4 and Comparative Examples 1 to 4.

  In Examples 1 to 4, all of the peelability to glass, the storage stability and the repellent effect were good. On the other hand, since the polymer (I) was not blended in Comparative Example 1, the curability was good but the peelability to glass was insufficient. Moreover, since the comparative example 2 had much pest repellent amount, the storage stability worsened. In Comparative Example 3, the amount of the polymer (II) was as large as 300 parts with respect to 100 parts of the polymer (I). Further, since the amount of the pest repellent was as small as 2.4 parts by weight per 100 parts by weight of the total of the polymers (I) and (II), the pest repellent effect was insufficient. In Comparative Example 4, the polymer (II) was not blended, the curability was insufficient, and the polymer could not be peeled from the glass.

  As described above, the resin composition of the present invention can be easily peeled from glass that has been difficult to peel. Thereby, even if it is the adherend which consists of glass, such as a show window, when replacement | exchange of a pest repellent is required, it can peel from an adherend easily. Moreover, since the resin composition of the present invention can be shaped into a free shape and can be attached in a desired shape to a place where a pest is not desired to be approached, it can also be used as a decorative article. In addition, since the resin composition of the present invention is fast and chemically stable, it can be blended with various visual effect-imparting components such as a colorant, a phosphorescent agent, and a fluorescent pigment. Even if it is pasted in a place where it can be easily attached, it is possible to use a visual effect for decoration with a greater degree of freedom.
