ROYALSIL Inc. was established April 1, 2010.  As CEO & Founder,  I come to you with over 30 year’s experience in selling silanes, siloxanes, silicones, fumed and precipitated silica.

We specialize in both commercial and exotic silanes. ROYALSIL Inc. sells to and services a wide range of industries including but not limited to adhesives, building materials, caulks, coatings, plastics, rubber, sealants, or textiles.

In addition, our silane functionalities include, but are not limited to, acrylate, amino, epoxy, mercapto, polysulfide, vinyl, fluoro & more!

Our silanes are designed to enhance and give notable improvements in chemical resistance, flexibility, rheology, tensile strength, and wet adhesion.

Not only is ROYALSIL a dependable source of specialty silanes, but we also bring technical expertise for your benefit. My close to 30 years service selling and servicing silanes gives me a deep reservoir of knowledge to answer technical challenges. ROYALSIL invites you to review some expired patents and helpful articles. We depend on your continued satisfaction in order to earn and keep your business.
