Chii chinonzi Unsaturated Polyester Resin?

Pamwoyo payo,resin yepolyester isina kugutaipolymer inogadzirisa thermosetting inogadzirwa nekusanganiswa kwepolyhydric alcohols uye polybasic acids (imwe yacho inenge isina kuguta). Iyi "kusaguta" ndiyo muto wakavanzika; inobvumira resin kubatanidza uye kushanduka kubva mumamiriro emvura kuita yakasimba, inogara kwenguva refu kana yakabatanidzwa necatalyst.

2. Isophthalic Unsaturated Polyester Resin

"Iso resin" ndiyo inonyanya kukosha. Nekushandisa isophthalic acid, chimiro chemamorekuru chinova chakasimba.
