特に塗料や接着剤の分野において注目されている。Reactive liquid rubber-based organic polymers such as liquid silicone polymers, liquid modified silicone polymers, liquid urethane polymers, and liquid modified polysulfide polymers have low viscosity, so they can be used as they are and have excellent processability. Since it is possible to obtain a cured product with excellent solvent resistance and weather resistance, it is attracting attention particularly in the fields of paints and adhesives from the viewpoint of being solvent-free.

部となるため塗布作業性および形成した硬化物の物性に
問題があった。Various studies have been conducted to improve thread breakability.
For example, improvements have been attempted by adding thixotropic agents such as light calcium carbonate, hydrogenated castor oil, and anhydrous silica, and by adding fillers such as silica sand. However, the method of adding a thixotropic agent does not fully demonstrate the desired effect, and the method of adding a filler is effective in improving thread breakage, but silica sand Therefore, there were problems with the coating workability and the physical properties of the cured product formed.

マー１００重量部に対し１０〜１００重量部である。The blending ratio of the filler is 10 parts of the reactive liquid rubber organic polymer.
The range is 200 parts by weight or less relative to 0 parts by weight. The reason for this is that if the blending ratio of the filler exceeds 200 parts by weight per 100 parts by weight of the reactive liquid rubber-based organic polymer, the rubber elasticity will be lost and the adhesiveness will also be reduced. A particularly preferable blending ratio of the filler is 10 to 100 parts by weight based on 100 parts by weight of the reactive liquid rubber-based organic polymer.

物性に好ましくない影響が生じる。1v) Mica is an aluminum silicate mineral having interstices, and representative examples thereof include muscovite (muscovite) and phlogopite (phlogopite). Mica is used in the form of particles with an average particle size in the range of 50 to 500 μm. If the average particle size of mica is less than 50 μm, the effect of improving thread breakage property will not be sufficiently exhibited. On the other hand, if the average particle size exceeds 500 μm, unfavorable effects will occur on coating workability and adhesive properties.

The range is 1 to 100 parts by weight relative to 0 parts by weight. The reason for this is that if the blending ratio of mica is less than 1 part by weight, the effect of improving yarn breakage by adding mica will not be sufficiently exhibited.
Moreover, if the blending ratio of mica exceeds 100 parts by weight, problems will arise in coating workability and physical properties of the formed cured product. A particularly preferable blending ratio of mica is 2 to 10 parts by weight based on 100 parts by weight of the reactive liquid rubber-based organic polymer.

Although it improves slightly, the spatula resistance during work is large and the application workability is poor. On the other hand, the compositions of Examples 1 to 5 have good thread breakability, low spatula resistance during operation, and no deterioration in adhesive properties.

It has good coating workability. Therefore, when filling the applicator cartridge and discharging it from the gun, or when applying adhesive or sealant in the container to a flat surface with a spatula, webbing can be used to remove adherends from areas other than the desired area. The problem of surface staining can be overcome.
