Product Details:

1. Introduction

SBR powder styrene-butadiene rubber is produced by emulsion polymerizing styrene and butadiene at low temperature (5°C) to form styrene-butadiene latex, and then grafting other monomers appropriately according to the production and use properties of coils and rubber bitumen non-cured coatings. It is a polymer elastomer material. After adding waterproof SBR powder rubber, because SBR powder rubber has active functional groups, it can produce a special activity in the waterproof membrane and coating, allowing the waterproof membrane or coating to interact with the cement in the cement during the curing process. Silicate radicals form compounds to create strong adhesion. While improving the adhesion between the membrane and the cement base layer, SBR powder can also greatly improve the low-temperature performance of the waterproof membrane or coating.

2. Function and Features

• Enhanced Adhesion: SBR powder improves the adhesion between the waterproof membrane or coating and the cement base layer, forming stronger bonds during the curing process.
• Waterproofing Performance: The addition of SBR powder significantly improves the waterproofing properties of the membrane or coating, ensuring it resists water penetration effectively.
• Low-Temperature Flexibility: It greatly enhances the low-temperature performance of the waterproof membrane, allowin it to remain flexible and functional in cold environments.
• Durability: SBR powder helps to increase the durability and resistance to environmental factors such as UV, temperature fluctuations, and physical wear.
• Eco-Friendly: SBR powder is non-toxic, eco-friendly, and compliant with international environmental standards.
