2. Product Overview

SR® 330 is an aqueous dispersion based on vinyl acetate, plasticized with dibutyl phthalate and stabilized with polyvinyl alcohol. It is a high-performance coating binder specifically designed for carpet back coating, either filled or unfilled, due to its excellent pigment binding power. The product is delivered as a white liquid with a solids content of 37 ± 1% and a viscosity of 40000 ± 10000 mPa·s (Brookfield RVT, Spindle 7, 20 rpm).

Vinyl acetate dispersions such as SR® 330 have become the backbone of modern carpet back coating technology. Unlike traditional latex or styrene-butadiene systems, vinyl acetate dispersions offer excellent filler loading capacity, good adhesion to natural and synthetic fibers, and compatibility with a wide range of compounding ingredients. SR® 330, with its dibutyl phthalate plasticization and polyvinyl alcohol stabilization, delivers excellent pigment binding power, making it a direct competitor to conventional carpet coating binders.

The primary applications of SR® 330 include:

Carpet Back Coating: Used as a primary binder in carpet back coating formulations, both filled and unfilled.

Textile Coating: Used in coating formulations for industrial textiles, upholstery fabrics, and technical textiles.

Nonwoven Binder: Used as a binder in nonwoven fabric production for filtration, hygiene, and industrial applications.

Fabric Sizing: Used as a sizing agent in textile finishing to improve fabric strength and handling.

Fiber Bonding: Used in fiber bonding applications for battings, waddings, and insulation materials.

The global carpet and textile coating market is projected to maintain steady growth, driven by increasing construction activity, growth in automotive interiors, and demand for technical textiles. In the Middle East and Central Asia, carpet and textile production is expanding rapidly, driving demand for high-quality vinyl acetate coating binders. The Supply Chain Department at Sahi Rasa Company is positioned to serve this growing demand by offering reliable access to high-quality SR® 330 at competitive prices.
