        Product Description

        Product description

        Structural formula:

        Empirical formula:C10H20O5Si

        Molecular weight:248.4

        CAS No.:2530-85-0


        Chemical name:γ-Methacryloxypropyltrimethoxysilane


        Properties

        LT-570 is a bifunctional silane possessing a methacrylic organofunctional group and a tri- mehoxysilyl inorganic group. The dual nature of its reactivity allows it to bind chemically to both inorganic materials (e.g. glass, silica) and organic thermoset resins thus functioning as adhesion promoter, co-monomer for polymer synthesis, crosslinker, and surface modifier. 

        The use of LT-570 as a coupling agent in glass fiber-reinforced or filler-modified plastics improves filler dispersibility while reducing the filler's sedimentation tendency. It also results in a major reduction in the melt viscosity of casting resins, as well as a marked improvement in the mechanical properties of glass-fiber-reinforced or mineral-filled plastics. In addition, use of LT-570 in these materials leads to a sizable increase in moisture (vapor) resistance as well as greater resistance to acids and bases. Used as a co-monomer in 

        polymers, LT570 produces binders that exhibit much improved wet scrub, abrasion and scratch resistance because of crosslinking and strong adhesion to the base. As a component of free-radical curable adhesives and sealants, it leads to improved mechanical properties and enhanced substrate adhesion.

        LT570 is a clear, colorless, light and heat sensitive liquid with a characteristically sweet odor. It is soluble in alcohols, and aliphatic or aromatic hydrocarbons.


        Technical data

        1.png


        Reactivity

        LT570 is highly miscible with standard organic solvents, such as alcohols, toluene and acetone, but practically is insoluble in neutral water. However, by adjusting the pH to between 3 and 4 with a hydrolysis catalyst (e.g. acetic acid), an aqueous solution of up to 5 percent by weight can be obtained. The resulting clear solution should be used as soon as possible (within 1-2 days), before siloxane formation has proceeded too far. Deactivation of LT570 by siloxane formation is signalized by clouding of the aqueous solution.

        The hydrolysis of alkoxy group produce methanol and reactive silanol (Si-OH) groups 

        which can bond to a variety of inorganic substrates. The methacrylate groups interact with the polymer. Examples of suitable inorganic substrates are glass, glass fibers, glass wool, mineral wool, silicic acid, quartz, sand, cristobalite, wollastonite, silicate fillers, metal oxides and metals. Examples of suitable polymers include unsaturated polyester, vinyl esters and acrylates.


        Application and performance

        LT-570 is used as adhesion promoter in application such as:

        ★A constituent of glass fiber sizes (glass fiber fillers for unsaturated polyester resins and polyolefins).

        A finish for glass fabrics used in unsaturated polyester resins.

        As a surface modifier for pigments and fillers for thermosets (unsaturated polyester, such as MMA), thermoplastics (such as polyesters and polyolefins) and elastomers.

        As an additive for filler, peroxide- crosslinked elastomers.

        As an additive for casting resins (un- saturated polyester, MMA).

        LT570 is either applied to the inorganic substrate as a pretreatment by dipping, spraying, or coating or it may be added directly to the resin matrix (additive process). For pretreatment, the silane may be used

        Neat 

        Dissolved in an organic solvent.

        Dissolved in a mixture of organic solvent and water for partial hydrolysis.

        Completely hydrolyzed in aqueous solution.

        To prepare an aqueous pretreatment solution, approx. 1-5wt% LT-570 is dissolved in water that has been adjusted to pH 3-4 with acetic acid. The solution will turns clear when the

        silane has fully hydrolyzed. The clear solution of LT-570 hydrolysate must be used within 1-2 days; if it turns cloudy again it may no longer be used. In the additive process, LT570 is mixed with the resin or polymer before or together with the filler. A prerequisite for this method is compatibility of the silane with the resin since the silane must not react prematurely with the resin.

        When used correctly LT-570 can achieve the following properties, for example in a highly-filled unsaturated resin system:

        Optimum dispersion of the fillers/ pigments.

        Reduction in settling of the fillers/ pigments.

        A reduction in viscosity and improved flow properties of the resin.

        Improved mechanical properties of the molded products.

        Improved resistance of the molded products to boiling water, acids and alkalis.

        LT-570 can be used as monomer during resin synthesis (e.g. latex dispersions). It may partially replace the methacryl-functional monomers (usually 0.5-3%, but sometimes up to 20%). The thus incorporated silane functionality can lead to improved properties in the final application (e.g. coating or sealant) of such resins:

        Wet adhesion strength.

        Chemical resistance.

        Mar resistance.
