DOWSIL™ YOUJIE Neutral Silicone Sealant Cost-Effective Solution for Window Door Sealing


Basic Product Attributes

DOWSIL™ YOUJIE Neutral Silicone Sealant is a single-component, room-temperature curing silicone sealant designed for cost-effective building sealing applications. Available in Translucent, Black, Grey, and White colors with eco-friendly 590ml soft pouch packaging.


Product Core Introduction

This economically priced sealant delivers exceptional performance in residential window and door sealing. Its neutral curing formula ensures non-corrosive adhesion to glass, fluorocarbon-coated aluminum, and steel substrates. The ready-to-use formulation cures upon exposure to atmospheric moisture, maintaining long-term flexibility after curing.


Special attribute enhancement

The patented soft pouch reduces packaging waste by 35% compared to traditional cartridges while maintaining precise dispensing control.

Neutral curing chemistry prevents substrate corrosion even on sensitive metals. Laboratory tests confirm >530% elongation after curing, enabling superior movement accommodation.
