Colophony of not saturated polyester (Unsaturatedpolyesterresins) is to point to to not saturated key is had on molecular catenary (be like Shuang Jian) polyester high polymer. Not saturated n duality is acerbity (or acid anhydride) , saturated n duality is acerbity (or acid anhydride) as mellow as n duality (or multivariate mellow) undertake below certain condition condensation polymerization reaction forms not saturated polyester, not saturated polyester is deliquescent the cross-linking monomer at certain amount (like styrene) in form liquid colophony to be colophony of not saturated polyester namely. Colophony of not saturated polyester is joined cause a system to be able to react form stereo and reticulate structure not dissolve not material of frit high polymer, the colophony of hot solid sex that is a kind of model so. The advantage with colophony of not saturated polyester and more distinct than having its photograph of colophony of sex of solid of other and numerous heat. Introduce according to expert of net of not saturated colophony, colophony of not saturated polyester has good fabricating characteristics, can be in room temperature (not under 15 ～ 20 ℃ ) , often press next solidify to shape, do not release any by-product. And resinous viscosity is more appropriate, can use a variety of treatment to shape method, if hand paste shapes, eject shapes, pull crowded shape, note model to shape, twine shape etc. Colophony of not saturated polyester is called on industry the contact shapes or low pressure shapes colophony of hot solid sex.
