Product Description

 

Product Description

 

ULEAT00-200 is a hydrophilic fumed silica produced through high-temperature (1000°C+) hydrolysis of chlorosilane in a hydrogen-oxygen flame. As a versatile filler and rheology modifier, it enhances performance in RTV/HTV silicone rubber, adhesives, coatings, inks, and leather treatments.

 

Detailed Product Description

1. Key Features:

Excellent Reinforcing Properties
Enhances mechanical strength in silicone rubber and elastomers.

Superior Rheology Control
Improves viscosity and thixotropy in adhesives, coatings, and inks.

Highly Stable & Dispersible
Ensures even distribution in liquid and solid matrices.

Wide Application Range
Suitable for HTV silicone rubber, batteries, construction, and personal care.

Thermal & Chemical Resistance
Performs effectively in high-temperature and harsh environments.

 

2. Applications

 

High-Temperature Vulcanization (HTV) Silicone Rubber
This best-selling fumed silica significantly improves tensile strength, tear resistance, and durability in silicone rubber products.
Adhesives & Sealants
Acts as a highly effective thickening and anti-sagging agent, ensuring precise application and strong bonding.
Coatings & Inks
Provides superior matting, anti-settling, and flow control, enhancing finish quality.
Unsaturated Polyester Resins (UPR)
Improves mechanical properties and prevents sedimentation in composite materials.
Colloidal Batteries & Insulation Materials
Enhances electrolyte stabilization and thermal insulation performance.
Personal Care & Food Additives
Used as an anti-caking and thickening agent in cosmetics and food-grade applications.
Building Materials
Strengthens cement, mortars, and other construction composites.
