Silane Terminated Polyether Polymer SD-380

◼ High Activity, Low ¨C medium Modulus

◼ High transparence

◼ Good adhesion strength and tensile elasticity

◼ Fast curing , non-tin catalysts used if needed, more eco-friendly

◼ Excellent water resistance and solvent resistance

◼ Excellent elastic recovery rate

◼ Excellent storage stability

◼ Solvent free, odourless, eco-friendly

◼ Excellent aging and yellowing resistance

It is is alkoxy silane terminated polyether polymer and can be quickly dissolved in ordinary organic solvents (such as ethanol), but almost insoluble in water .So the raw materials in the formula system are mostly oil-soluble substances.Different from polyurethane and silicone system, this formulation have no solvent and isocyanate, as well as no bubbles and odour generated from curing. It is especially suitable for construction industry, transportation industry and general industry application.

It is used as base polymer in elastic sealants, elastic structure sealants, encapsulate adhesives and coatings . The curing mode of the polymer is moisture curing, It can be made into a single component or two components system, mainly for Transportation industry sealant, Medium, Low modulus construction sealant, Transparent encapsulate adhesive,Personal DIY and Eco-friendly decoration sealant

It can be removed before curing by the general solvent, such as ethanol, dimethyl carbonate. After curing can only be removed by mechanical means.

This product is supplied in 50kg plastic drum lined with aluminum foil bag, 200kg drum lined with aluminum foil bag, or 1000kg IBC.

Because this product is moisture sensitive, if unopened and stored at 4¡æ -30¡æ dry environment, the shelf life is 12 months. Use it as soon as possible if opened, the remain products should be resealed and stored at 4¡æ -30¡æ dry environment. But if shelf life expired, you can still use it only after your positive confirmation of production performance.
