Coupling Agent price | | Product No.锛歀N-560
Product description
Empirical formula: C9H20O5Si
Structural formula:
Molecular weight: 236
CAS No.: 2530-83-8
Chemical name: 3-Glycidoxypropyltrimethoxysilane
Properties
LN560 is a bifunctional silane possessing a reactive organic epoxide and hydrolysable inorganic methoxysilyl groups. The dual nature of its reactivity allows it to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermoplastics, thermosets or elastomers) thus functioning as adhesion promoter, cross- linker, and/or surface modifier.
The use of LN-560 as a coupling agent in mineral-filled plastics improves filler dispersibility, reduces its sedimentation tendency and greatly lowers the resin's viscosity. In addition, it leads to higher filler loading and a marked increase in water (vapor) resistance, as well as resistance to acids and bases. As a component of adhesives and sealants, LN560 improves both adhesion to the substrate and mechanical properties such as flexural strength, tensile strength and modulus of elasticity.

Reactivity
In the presence of water, the methoxy groups of LN-560 hydrolyze to form reactive silanol groups which can bond to a variety of inorganic substrates. The organophilic epoxy group can undergo a ring-opening reaction with nucleophiles such as alcohols and amines. An acidic or basic catalyst may be required.
Examples of suitable inorganic substrates are glass, glass fibers, quartz, cristobalite and metals. It may be used with such polymers as epoxy, phenolic, polyurethanes, polysulfides, PVAC, acrylates.
Application :
1.It is mainly used to improve the adhesion between the surface of organic material and inorganic material, for example, the treatment of the glass fabric in glass steel and the silicon stuffing in plastic, rubber, paint, coating, etc. Also used in adhesive to strengthen the adhesion. The suitable resin include epoxy, phenol aldehyde, melamine, polysulfide, poly amino ester, polystyrene, etc.
2.Improve the adhesion between inorganic stuffing, base material and resin, hence improve the mechanical strength, electric property of composite material and high retention in wet state.
3. As the surface treating agent of inorganic stuffing, widely used in pottery clay, talcum powder, silicon grey clay, white carbon black, silica, aluminum powder, iron powder, etc.
4. As epoxy sealing agent to stuff silica, epoxy concrete remedy material or coating to stuff sand and epoxy mould material to stuff metal. 5. Improve the adhesion of double-component epoxy sealing agent, acrylic acid latex, sealing agent, polyamino ester, epoxy coating.
