There is provided herein a silylated polyurethane composition, a process of preparing a silylated polyurethane polymer, and an adhesive, sealant or coating containing a silylated polyurethane made therewith.

Moisture-curable silylated polymer resin composition with reduced moisture sensitivity

A batch or continuous process for preparing silylated polymers having low color and color stability comprising silylating a prepolymer having reactive functional groups with a silylating agent and optionally quenching the silylated polymer, where a stabilizer package containing at least one phosphite stabilizing agent is used.

Process for the preparation of silylated polymers having low color and color stability

A continuous process for preparing a silylated polymer comprising a silylation step where a prepolymer having reactive functional groups, a first intermediate product, is reacted continuously with a silylating agent in an endcapping tubular reaction unit to form a second intermediate product, and where at least a portion of the second intermediate product is backmixed continuously with the first intermediate product to form the silylated polymer. The continuous process may further comprise a stabilization step, a quenching step or both a stabilization step and a quenching step.

Process for the preparation of silylated polymers employing a backmixing step

There is provided herein a method of preparing an isocyanatosilane including reacting an olefinic isocyanate with a hydridosilane in the presence of a dinuclear rhodium complex under hydrosilylation conditions.

Preparation of isocyanatosilanes

The present invention relates to a process for preparing silylated polyurethane polymers which have increased stability under ambient condition or storage toward atmospheric moisture, in the presence of at least one of titanium-containing catalyst or zirconium-containing catalyst and to silylated polyurethane polymer compositions comprising these catalysts.

Process for the preparation of silylated polyurethane polymers using titanium-containing and zirconium-containing catalysts

A process is provided for making a moisture-curable silylated resin composition by reacting (i) at least one polyol, (ii) at least one polyisocyanate and (iii) at least one isocyanatosilane, optionally in the presence of catalyst, wherein the NCO/OH ratio is less than 1. The resulting moisture-curable silylated resin composition is useful in the manufacturer of each product as moisture-curable sealants, coatings and adhesives.

Process for making moisture-curable silylated resin composition, the resulting composition and moisture-curable products containing the composition
