We have a very strong R&D team ,Prof. Lin Start  clay chemicals study since 1950'; under his leadership we successfully completed several national clay related researching project ,Prof. Lin also awarded by China Central government as"Specialist has great achievenment"; Prof. Lin aslo complete an independent research on nanoclay for polymer using purpose in 2000,which research started earlier in 1990'.The nanoclay developed by Prof. Lin has been approved by Government as "Advanced material" and approval to start production for industrial using purpose. 

The Sino-Holding  Instruments and Technolog  is  a company with strives for innovation and is famous for the self-designed product: the Digital Rotating Viscometer.  This device possesses several patents on technical application and meets with all international standards and specifications. All of our 20 digital rotating viscometers when compared for accuracy, convenience of use, automation and appearance are the one of best in China. This high value and high quality performance enables our products to be favoured by customers from Southeast Asia, the Middle East, Europe and the Americas as an alternative for other high cost equipment. Our company is dedicated to providing customers with reliable instruments and meters that are easy to use and rapid in measurement all while meeting and surpassing international standards and staying cost-effective.

The history of the main products and the company 

1.Organophilic bentonite -- Organoclay rheological additive :main usage in paints,inks,oil based drilling ,grease,sealants industries. Background 

    a) In 1980' ,We developed and started producing Na-bentonite based organoclay such as :381M,182B 

    b) At the beginning of 1990',We developed and produced Ca-bentonite based conventional organoclay . 

    c) In 1996,We established the organoclay producing line in China.

    d) In 1999,we developed and started producing series of easier dispersing organoclay .And becoming the  company who has technology to produce this advanced material in China 

    e) In 2000,The company developed the Nano-material class smectite products for polymer (Nanoclay). 

2. Purified bentonite -- Inorganic gellant rheological additive :main usage in emulsion paints,inks,oil based drilling ,grease,sealants industries. Background From 1980' till today,we are the first one developed and produced the SM series of inorganic purified bentonite gellants. 

3. Acid treated bleach earth Main usage :refining and purify mineral oil,cooking oil and so on. Background a) Since 1980' producing powder bleaching earth main for mineral oil and cooking oil. b) In 1995 start producing granular activated bleaching earth. 

4. Pet litter (CAT SAND) Main usage for cat and dog to absorb the waste ,mainly for abroad market. 

5. Bentonite for civil Engineering Main usage for underground engineering as drilling mud and sealant . In bentonite industrial field, It is a well known company,and awarded as the leading enterprise in zhejiang Province,and also awarded as the top class quality enterprise. 

6.BEST GEL series of organoclay property l This series of organoclay is the developed products ,compare with conventional organoclay, FRGEL series have better dispersing and gelatinating property , because we using advanced new technology : 

    a) Advanced separate technology enable our bentonite purified to 95-98% and average size about 0.35 u,and other producer in China, they can only provide organoclay with bentonite around 85%,and average size around 0.8u. 

    b) Select the suitable amine to meet the bentonite . BESTGEL series of organoclay better than the local other producer in quality. Till today, most of these main paints and inks company are all using BEST GELFRGEL series of organoclay rheological additive. And thenewNano -aditivesFRGEL MP2000 alsostartcommercial selling in totheconstruction paints market in 2010. In Jun.,2017, The new plantannually capacity increased  , and meanwhile theNew Labstart usingfor Global customers.
