Solvent Based Nano Silica Dispersion CAS 7631-86-9 is uniformly dispersed colloidal silica in organic solvent. It serves as strength enhancer for adhesives and sealants, improving tensile strength, hardness and thixotropic property of the system.

Product Detail

Nano Silica Dispersion CAS 7631-86-9 Solvent Based Strength Enhancer for Adhesive Sealant

Product Overview

Solvent Based Nano Silica Dispersion (CAS 7631-86-9) is colloidal silica with nano silicon dioxide evenly dispersed in organic solvent. It can be well compatible with various solvent-based resin systems. When applied in adhesives and sealants, it effectively enhances mechanical strength, surface hardness and anti-sagging thixotropy. Meanwhile, it improves wear resistance and dimensional stability of cured products, acting as high-performance reinforcing and rheology control additive for adhesive and sealant formulations.

Core Features

Excellent Dispersion Performance: Nano particles are stably suspended without obvious sedimentation, easy to blend into resin systems.
Good Compatibility: Matches multiple solvent-based resins such as polyurethane, epoxy, silicone and acrylic resin.
Reinforcement Effect: Improve tensile strength, shear strength and hardness of cured adhesive and sealant.
Adjustable Thixotropy & Anti-sagging: Endow coating and sealing materials with outstanding anti-sagging property during construction.
Low Impurity Level: Less ionic impurities, avoiding adverse impact on curing system.
Stable Storage Property: Maintain uniform system within validity period under proper preservation.

Product Specifications

Product Name: Solvent Based Nano Silica Dispersion

CAS No: 7631-86-9
