Anti-blocking Nano Silica Dispersion CAS 7631-86-9 is stable aqueous silica dispersion. Uniform nano silica particles form micro uneven structure on film surface to achieve excellent anti-blocking effect. It is ideal functional additive for plastic film surface coating.

Product Detail

Anti-blocking Nano Silica Dispersion CAS 7631-86-9 for Plastic Film Surface Coating

Product Overview

Anti-blocking Nano Silica Dispersion CAS 7631-86-9 is stable water-based nano silica dispersion. Uniformly dispersed nano SiO₂ particles can form micro-convex and concave structure on the surface of plastic film coating layer, effectively reduce the adhesion between film layers and realize outstanding anti-blocking performance. The product features good compatibility with water-based coating systems, stable dispersion and low impact on coating transparency. It is a professional anti-blocking functional additive for plastic film surface coating.

Core Features

Excellent Anti-blocking Effect: Form micro uneven surface to prevent film adhesion during rolling and storage.
Stable Aqueous Dispersion: Nano silica particles are not easy to agglomerate, long-term storage with good stability.
High Transparency: Less influence on the clarity and light transmittance of transparent plastic films.
Good Resin Compatibility: Compatible with water-based polyurethane, acrylic emulsion and other common binders.
Improve Surface Sliding Property: Moderately enhance surface smoothness, facilitate film winding and processing.
Environmentally Friendly Water-based Formula: Low VOC, meet the environmental requirements of film coating production.

Product Specifications

Product Name: Anti-blocking Nano Silica Dispersion

CAS No: 7631-86-9

Appearance: Translucent homogeneous liquid

Active Ingredient: Nano Silicon Dioxide

Core Function: Anti-blocking, surface slip modification

Main Applications: Plastic film surface coating

Application Scope

This anti-blocking nano silica dispersion is widely used in plastic film surface coating industry. Suitable for packaging film coating, printing base film coating, optical protective film coating, food contact film surface treatment and other fields. It solves the blocking problem of rolled films under stacking pressure, guarantees continuous production and post-processing performance of plastic films.

Usage Guide

Stir raw material evenly before use. Slowly add nano silica dispersion to coating liquid under low-speed stirring and maintain uniform mixing. Avoid excessive high-speed stirring to prevent viscosity rise or gelation. Tightly seal the container after use to avoid water evaporation and particle agglomeration.
