Product Details:

1. Introduction

SBR latex (SBR-60) as a modifier for emulsion asphalt (bitumen emulsion) is a stable emulsion synthesized by butadiene and styrene through low-temperature emulsion polymerization. This product is specially developed according to the characteristics of modified emulsion asphalt (bitumen). It is widely used in road engineering, including applications such as micro-surfaces, slurry seals, spraying, and other modified emulsified asphalts. It can also be used in waterproof coatings, waterproof ointments, and similar materials. Modification by styrene-butadiene latex improves temperature-sensing performance, low-temperature performance, viscosity, anti-crack performance, anti-aging properties, and other key indicators.
