Subject: CAPATUE introduces a new global product model system for its Organofunctional Silane products

Dear Customer & Partner,

Thank you for your business and continuous supports to CAPATUE. This letter is to inform you that we are changing the product model for our organofunctional silanes. The new product model includes letters and characters to indicate the organofunctional groups, alkoxyl groups and other chemical structures of the organofunctional silanes. This change also allows CAPATUE to unify its product model in both domestic and global market.    

The original KH- series silane coupling agent is named by the Chinese Academy of Sciences in the 1970s, however this nomenclature only contains 6 typical silane products from KH-540 to KH-590. After decades of development, we have developed dozens of different the silane coupling agents, the old KH- model is no longer applicable for this new situation. So now a systematic nomenclature is in need and we are pleased to introduce a new global product model system for our Organofunctional Silane products. The details are as below for your information:

1. Conversion table that cross‐references old product model to the new product model. 

2.The Raw of Naming

2.1 Basic Principle s

The model must be unique; the same model can not be used for two products. The naming of product or name change must be presented by the production department, can be used only after the sign of Marketing Department and Standard room registration.

2.2 The way of naming

The way of naming please see the below chart:

2.2.1 Product type code

It is composed of three English letters, using the first letter of Silane Coupling Agent “SCA” as the code of Silane Coupling Agent products.

2.2.2 Organic functional groups

It is composed of 1-2 English or Greek letters, English letters are basically adopted by the beginning letters of Organic functional groups, if any repetition, will use other letters of the English word to instead. Its specific code and its symbol meaning, see table 1.

TABLE 1 ：Organic functional groups.

2.2.3 Product code number

It is composed of two digits, try to avoid repetition. Generally related to the information of corresponding products abroad (mainly refer to the model of Momentive, amino, epoxy, Acryl, Ureido, Isocyanato, Sulfur Silanes, etc., such as the SCA - A10E corresponds to A - 1100, the SCA - E87M corresponds to A - 187, the SCA - R74M corresponds to A - 174, the SCA - V71M corresponds to A - 171, the SCA - S89M corresponds to A 189-189, SCA - S69X corresponding to Si69, etc.), or the number of functional groups of silane (such as the number of amino in amino silane, single amino, double amino and three amino named respectively A10, A20 and A30, fluorine base number of fluoro silane, such as the F13C8 in SCA - F13C8M said  thirteen n-ethylperfluorooctanesulfonamido), or the number of carbon atoms in alkyl silane (such as the SCA - K08E ,08 said octyl , ie 8 carbons) .

2.2.4 Alkoxy or alkyl code

It is composed of one or two English letters, basically the initial letters of alkoxy or alkyl .If can not adopt this method, It is name based on the number of carbon atoms, its meaning as shown in the table 2.

Table 2 ：Alkoxy or alkyl code

3.Model change of undisclosed chemicals or mix products are as follow:

“PCA” stands for Powder Coupling Agent ； “ADP” indicates Adhesion Promoter

We ask that you reference the new product model beginning with new orders dated July 1^st 2018.  CAPATUE will not accept orders for the existing product model beyond September 30, 2018. After this date, only orders with the new part number structure will be accepted.

In the transitional period, both old and new product models can occur simultaneously or separately on the product labels, invoices, COA, delivery receipts, product brochures, websites and other medias and materials (such as KH-550 labels may be SCA-A10E (KH-550)).Old customers can change gradually, new customers should all use the new models, and all customers will use the new model only after the transitional period.
