正奇化工公司位于杭州灣上虞市境內(nèi)，是中國唯一生產(chǎn)納米級(10-15nm）透明氧化鐵系列顏料的企業(yè)。現(xiàn)生產(chǎn)透鐵紅、黃、綠、棕、黑五個(gè)品種十多個(gè)牌號，年生產(chǎn)能力1200噸。透鐵顏料世界上只有少數(shù)發(fā)達(dá)國家能夠生產(chǎn)，其顏色只有黃、紅兩種。納米級透明氧化鐵顏料開發(fā)項(xiàng)目，被列入國家級星火計(jì)劃，浙江省新產(chǎn)品開發(fā)計(jì)劃，產(chǎn)品填補(bǔ)國內(nèi)空白，其中納米級透鐵綠世界獨(dú)創(chuàng)。經(jīng)過六年研究開發(fā)，生產(chǎn)工藝成熟，產(chǎn)品質(zhì)量穩(wěn)定，品質(zhì)已達(dá)國際一流水平，完全可以替代進(jìn)口，而價(jià)格大大低于同類進(jìn)口產(chǎn)品，目前產(chǎn)品90%出口歐美國家。
   納米級透鐵顏料，無毒、無味，具有很好的耐溫、耐候、耐酸、耐堿以及高彩度、高著色力、高透明度和強(qiáng)烈的吸收紫外線等卓越性能，是傳統(tǒng)顏料無法比擬的。它可廣泛應(yīng)用于高檔汽車涂料、木器涂料、建筑涂料、防腐涂料、粉末涂料及塑料、尼龍、橡膠、油墨等領(lǐng)域。
   納米材料，二十一世紀(jì)的新材料。納米級透鐵系列顏料的開發(fā)成功，將改變我國高檔顏料和高性能涂料產(chǎn)品長期依賴進(jìn)口的狀況，特別對我國傳統(tǒng)涂料產(chǎn)品的升級換代，必將產(chǎn)生重大的影響。
