2. Product Overview

SR® 777 is a non-plasticized aqueous dispersion based on acrylic and methacrylic acid esters. It is a high-performance binder specifically designed for the manufacture of dispersion-based gloss paints, wood stains, vinyl silk paints, primers, and deep shade paints. The product is stabilized with surfactants and delivered as a milky white liquid with a solids content of 46 ± 1%.

Acrylic dispersions such as SR® 777 have become the backbone of modern waterborne coating technology. Unlike traditional solvent-borne alkyd systems, acrylic dispersions offer significantly lower volatile organic compound (VOC) emissions, reduced fire hazard, easier cleanup, and improved environmental compliance. SR® 777, with its optimized particle size of approximately 0.12 microns, delivers excellent film formation, high gloss development, and superior durability, making it a direct competitor to conventional solvent-based binders in premium paint applications.

The primary applications of SR® 777 include:

Gloss Paints: Used as the primary binder in waterborne gloss paints for interior and exterior walls, trim, and doors.

Wood Stains and Varnishes: Used in pigmented wood coatings, impregnating stains, and stain varnishes for furniture and joinery.

Vinyl Silk Paints: Used in mid-sheen emulsion paints for interior walls.

Metal Coatings: Used as a binder in waterborne metal primers and topcoats.

Masonry Paints: Used in exterior masonry coatings and window frame coatings.

Fiber Cement Coatings: Used in coatings for fiber cement boards and panels.

Deep Shade Paints: Used in highly pigmented deep-tone formulations due to excellent pigment binding capacity.

Primers: Used as a binder in waterborne primers for various substrates.

The global acrylic binder market is projected to maintain steady growth, driven by increasing demand for eco-friendly coatings, stricter VOC regulations, and growing construction activity in emerging markets. In the Middle East and Central Asia, waterborne acrylic binders are gaining market share as countries in the region modernize their construction sectors and adopt international environmental standards. The Supply Chain Department at Sahi Rasa Company is positioned to serve this growing demand by offering reliable access to high-quality acrylic dispersions at competitive prices.

5. Industries & Factories Using This Product

SR® 777 acrylic dispersion is utilized across a diverse range of coating and paint industries. The following industries and their factories are the primary users of this product:

Paint and Coating Manufacturers: Waterborne gloss paint producers, emulsion paint factories, architectural coating manufacturers, and decorative paint companies use SR® 777 as a primary binder for gloss, semi-gloss, and silk emulsion paints. Factories producing waterborne trim paints, door paints, and window frame coatings rely on SR® 777 for its excellent wet adhesion and gloss development.

Wood Coating Factories: Furniture coating manufacturers, joinery coating producers, and wood stain formulators use SR® 777 in pigmented wood coatings, impregnating stains, and stain varnishes. The product's ability to form clear, crack-free films with high flexibility makes it ideal for wood applications where dimensional movement occurs.

Metal Coating Plants: Industrial metal coating factories use SR® 777 in waterborne metal primers and topcoats for steel structures, machinery, and metal furniture. The product's alkali resistance and adhesion properties are particularly valuable in these applications.

Construction Paint Producers: Factories producing masonry paints, exterior wall coatings, and fiber cement board coatings use SR® 777 for its durability and pigment binding capacity. EIFS (External Insulation and Finish System) manufacturers also use SR® 777 in base coats and finish coats.

Deep Shade Paint Manufacturers: Due to its high pigment binding capacity, SR® 777 is favored by manufacturers of deep-tone and highly pigmented paints, where conventional binders may struggle to maintain film integrity at high pigment volume concentrations.

Industrial Paint Factories: Manufacturers of general industrial coatings, maintenance paints, and protective coatings use SR® 777 as a binder in waterborne formulations designed to replace solvent-based systems.

6. Key Properties & Advantages

SR® 777 offers a distinctive combination of properties that make it a superior choice for waterborne coating applications:

Excellent Wet Adhesion: The product demonstrates improved wet adhesion on old alkyd resin paint films under the influence of water and simultaneous mechanical stress, making it ideal for repainting applications over aged solvent-based coatings.

High Gloss Development: The optimized particle size of approximately 0.12 microns and controlled surfactant system enable high gloss values in dried paint films, meeting the aesthetic requirements of premium gloss paints.

Good Ageing Resistance: Paint films based on SR® 777 exhibit good resistance to ageing, maintaining their appearance and protective properties over extended service life.

High Flexibility: The low MFFT of 13°C combined with a calculated Tg of 24°C provides a balance between film formation at ambient temperatures and final film hardness, ensuring both flexibility and durability.

High Alkali Resistance: The acrylic backbone provides excellent resistance to alkaline substrates such as fresh concrete, cement render, and masonry, ensuring long-term coating integrity.

Low Water Absorption: Dried films show low water absorption, contributing to blister resistance and long-term protection of the substrate.

Broad Formulation Compatibility: SR® 777 is compatible with the usual titanium dioxide and colored pigments as well as fillers, allowing formulators to develop a wide range of paint types using standard raw materials.

Environmentally Friendly: As a waterborne dispersion, SR® 777 enables the formulation of low-VOC paints, helping manufacturers comply with increasingly strict environmental regulations in target markets.
