Manta L310 is N-octyltrimethoxysilane.


Product Description

Manta L310 is N-octyltrimethoxysilane. Due to its methoxy functionality, it hydrolyzes significantly faster than its ethoxy counterparts, making it exceptionally effective for rapid curing applications. Upon reacting with atmospheric or substrate moisture, it deeply penetrates mineral matrices and forms a permanent, breathable, water-repellent siloxane network. It imparts uniform surface hydrophobicity with a dry, non-tacky feel, perfectly preserving the substrate’s original appearance.

Equivalent to Dow XIAMETER™ OFS-6665, Evonik Dynasylan® OCTMO, and Shin-Etsu KBM-3083).

Applications

  • Premium Stone Protection (Primary): Deeply penetrates marble, granite, and sandstone. Provides breathable waterproofing and anti-efflorescence with a dry, non-tacky finish, completely preserving the natural appearance.
  • Concrete & Masonry Waterproofing: Used as a highly effective penetrating sealer or integral admixture. Protects against water absorption, freeze-thaw damage, and chloride ingress without blocking pores.
  • Mineral Filler Modification: Enhances the hydrophobicity and dispersibility of fillers (e.g., silica, talc, glass fibers) in plastics, rubber, and coatings, while improving electrical insulation.
  • Glass & Ceramic Coatings: Creates an ultra-thin, durable hydrophobic layer, offering excellent anti-fouling and easy-to-clean properties for architectural and photovoltaic glass.
