組成物との接合強度に優れているという利点がある。Furthermore, when forming the resin composition of the present invention, glass fiber, carbon fiber, molybdenum disulfide, etc. may be added to the above-mentioned fluid unsaturated polyester resin to strengthen its strength or improve its surface friction characteristics. It is also possible to do so as long as the effects of the present invention are not impaired. Furthermore, when coating the surface of an unsaturated polyester resin with a resin composition as in the above example, the unsaturated polyester resin to be coated may be completely cured, or the unsaturated polyester resin coated may be completely cured, or it may be completely cured. It may be in a gel state. In the latter case, there is an advantage that the bonding strength with the coating resin composition is particularly excellent.

というように多くの著効を発揮するものである。The resin composition of the present invention can be applied to housing materials such as bathtubs, toilet bowls, wash basins, and various daily miscellaneous goods by taking advantage of its excellent frictional properties, abrasion resistance, and stain resistance. It can be used for structural materials, mechanical parts, etc. In particular, if it is used on the bottom of a boat or yacht, taking advantage of its low adhesion to foreign objects, it will have the effect of preventing water blur from adhering to it, and if used as a plastic mold, it will not adhere to molded products. Good removability eliminates the need for mold release agents such as silicone. In addition, when used in toilets and basins in washrooms installed in railway vehicles and other transportation facilities, it exhibits many effects such as being lighter in weight than the conventionally used stainless steel. It is.

20 parts by weight were added and thoroughly mixed using a mixer. Next, about 1% of benzoyl peroxide was added to the mixture and further mixed with a mixer to form an unsaturated polyester resin type 3.
A coating was applied by spraying on the resin composition to a thickness of about 0.5M to form a gel coat layer 2 made of the resin composition of the present invention. Then, it was kept at a temperature of 80 to 130° C. for about 30 minutes to be cured, thereby forming a surface coating layer 2.

The particles of 47-fluorinated ethylene resin (average particle size 3

In the surface coating layer 2 made of the resin composition, particles of tetrafluoroethylene resin, which has low adhesion to foreign substances, are dispersed between unsaturated polyester resins, so that dirt does not easily adhere to the surface and does not adhere easily. The stains were easily removed. Therefore, after using the bathtub, the limescale can be cleaned very easily, and since the glass fibers in the internal frame 1 are not exposed to the surface, the bathtub has the advantage of not causing discomfort to the user. Furthermore, since the internal frame 1 is made of glass fiber-reinforced unsaturated polyester resin, it has sufficient strength and significantly improves the commercial value of the bathtub.
