Abstract：
CapatueTM DLC-S89M dry silane is a convenient form of traditional liquid organo-functional silane coupling agent 3-Mercaptopropyltrimethoxysilane with 65% high active concentration; it is a free-flowing powder. CapatueTM DLC-S89M dry silane offers the benefit of easier handling and weighing, quicker incorporation during mixing and a longer shelf life.
This product has a mercapto organo-functional group and can be over a broad range of applications to provide superior bonds between inorganic substrates and organic polymers. The sulfur function reacts with a wide array of thermoset, thermoplastic and elastomeric materials.
CapatueTM DLC-S89M dry silane functions by chemically coupling the filler to the backbone of the polymer during vulcanization, compounding or crosslinking, and it is mainly used at sulfur curing systems.

Applications:
DLC-S89M reacts with fillers containing silanol groups during mixing and with the polymer during the vulcanization process under formation of covalent chemical bonds. This imparts better tensile strength, higher module, reduced compression set, increased abrasion resistance and optimized dynamic properties. DLC-S89M is used in many applications where white fillers containing silanol groups are involved and optimum technical properties are required.
1、Tires: An excellent reinforcing agent in tires to reduce heat built-up, reduce rolling resistance and improve the tires´ wet grip.
2、Shoe Soles: Generally applicable silane for improving abrasion resistance of sole compounds containing precipitated silica.
3、Mechanical Rubber Goods: General use silane for achieving good dynamic properties, low compression set and high abrasion resistance in mixtures containing white fillers.
4、Adhesives and sealants: An excellent adhesion promoter to glass, aluminum, steel and other inorganic surface in polysulfide, nitrile and other rubber adhesives, sealants and coatings.
Packing:
The regular packing of this product is the fiber drum with internal PE bag and the net weight of it is 20kg/drum. Other tailor-made packing is also available upon customer’s request.
