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. 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.
One, overview 4, glass reinforced plastics of home of application of resinous of not saturated polyester shapes craft basically papers craft to give priority to with the hand, shape in all sorts of glass reinforced plastics the place in craft occupies scale to amount to 80% above. In recent years our country early or late from beautiful, day, meaning, flower, the country such as law, heart introduces hundreds (set) glass reinforced plastics is special equipment and product line, raised the integral equipment level of the industry greatly. What be worth to put forward particularly is conduit and lay aside canister twine product line and construction to assemble a technology to already amounted to international advanced level. In addition mould pressing technology, colophony delivers moulding, pulled the mechanization processing technology such as crowded technology to also get greater progress in recent years. Our country glass reinforced plastics shapes in all sorts of treatment method scale are like watch 2-8 place to show roughly.

(1) is not fiber to enhance resinous of not saturated polyester to apply coating of gel of UP of ① surface coating to be able to offer smooth, shining appearance, the daub on a wall that can be used at car of component of shipping, bathroom, recreation to wait, have be able to bear or endure outstandingly await a gender, be able to bear or endure sex of ability in swimming, oil resistant, acid-proof sex, hardness good, electric insulating properties pollutes tall, burnish admirably, not easily wait for an advantage. Gel coating colophony contains 50% ～ the UP colophony of 60% and 40% ～ the filling of 50% and dye. The UP resin that is used at gel coating has 3 sort model, namely 2 formic acid fasten benzene colophony, to benzene 2 formic acid - 2 formic acid are the adjacent benzene that colophony of 2 mellow departments mixes Xin Wu to be used lesser colophony. Before two kinds of types occupy gel coating to use 3/4 of resinous 2/3 ～ about, benzene 2 formic acid - the application that colophony of 2 mellow departments basically uses Xin Wu at a few high quality scales, if be used at shipbuilding industry, it is better to have because of them fight foaming characteristic, the loss of burnish is less also. ② is pouring the UP with important material is pouring material has bead light button, artificial marble to wait. The price of artificial marble is the 1/5 ～ 1/3 of natural marble value about, basically use as pool of dresser face, tub, closestool, hot spring, windowsill, doorcase and floor brick. When making UP pouring mix with colophony and filling, activator, shape next, solidify is become eventually goods. Gel coating often uses as the liner of the mould, also make the coating that synthesizes marble with acrylic department colophony sometimes. The filling of artificial marble is the filling with light quality of etc of broken makings of alumina of calcium carbonate, 3 hydration, glass normally. Polyester of sticky agent of ③ polyester glue uses range as glue sticky agent very extensive, can stick receive brush, wool to brush, fixed nut till the anchorage lever of the Liang Zhu of the building and mine tunnel. Etc blame enhances ④ polymer cement model the filling such as pink of use stone of product polymer concrete and clastic rock. The United States consumed the UP polymer cement that makes an appointment with 9000t 1997. This kind of cement can be used at on the spot to repair road, bridge and use at box of drainpipe, public facilities and animal to feed those who feed a passageway to be noted beforehand. The blame of UP enhances application to still include component of canal of coating, argil, other waste pipe, sealed, electron and TV terminal enclose wait for utility.
