SEARESIN 147: Universal Acrylic Resin for Genuine Leather Finishing
Anionic CoPolyacrylate Dispersion (30.0% Active, pH 7.0, Soft) — Very Good Covering Power, Natural Appearance & Good Handle, Good Plate Release, Excellent Print Cut Resistance & Print Definition, Very Good Flexing & Milling, Excellent Anti-Yellowing for All Kinds of Articles by Guangdong Seaton Advanced Materials Co., Ltd.
Introduction
Every finishing department needs one binder it can rely on for almost everything—one that hides what should be hidden, keeps what should look natural, releases cleanly from the plate, holds a printed pattern sharply, survives flexing and milling, and does not turn yellow. SEARESIN 147 is Guangdong Seaton Advanced Materials Co., Ltd.'s universal acrylic resin for genuine leather finishing—an anionic co-polyacrylate dispersion at 30.0% active substance and pH 7.0, supplied as an opaque, milky white liquid in a soft grade. SEARESIN 147 offers very good covering power, keeps a natural appearance with a good handle, has good plate release properties, resists print cut with good print definition, gives very good flexing and milling properties, and delivers excellent anti-yellowing performance. Applied as the main binder in all kinds of articles, it is the one resin a finishing line can build its standard recipe around.
Core Benefits
Very Good Covering Power, Natural Appearance & Good Handle
The most distinctive property of SEARESIN 147 is its very good covering power, combined with the ability to keep a natural appearance and good handle. Covering power is the base binder's ability to hide the leather beneath—the uneven dye, the buffed surface, the scars, the shade variation across a hide—and to present a clean, uniform, evenly coloured surface for finishing. Where a low-covering binder leaves the substrate showing through, forcing finishers to build heavy, over-pigmented coats that look artificial and feel stiff, SEARESIN 147 covers economically, so lighter, more efficient coats achieve an even, opaque result. Yet strong covering must not come at the cost of appearance: SEARESIN 147 still keeps the finish natural in look and good in handle, so the covered leather looks rich and leather-like rather than coated. This balance—efficient hiding without artificial heaviness—is exactly what corrected grain, buffed, and lower-grade leathers need to be upgraded into attractive finished goods.
Good Plate Release & Excellent Print Cut Resistance with Good Print Definition
SEARESIN 147 offers good plate release properties and excellent resistance to print cut with good print definition. In embossing, plate release is a production-critical property: if the finish sticks to the heated plate, the leather is torn, the pattern is smeared, and the plate must be cleaned, halting the line. SEARESIN 147 releases cleanly from the plate, allowing continuous embossing with sharp, clean patterns and minimal downtime. Print cut resistance addresses the other great risk in printing: the ink or the print operation cutting through the finish and exposing the substrate beneath, which shows up as patchy, broken, or blotchy print. SEARESIN 147 resists this cut-through while still reproducing fine print detail with good definition, so printed patterns, logos, and textures come out crisp and complete. For embossed and printed leather goods—shoe uppers, bags, and fashion articles—these two properties together decide the yield of the whole operation, and they are where SEARESIN 147 is strongest.
Very Good Flexing & Milling Properties
SEARESIN 147 provides very good flexing and milling properties. Finished leather is flexed constantly in service and milled aggressively in the plant, and both operations punish weak films. In milling, the tumbled leather rubs against itself and the drum wall; fragile finishes crack, craze, whiten, or peel, and the resulting leather must be reworked or downgraded. SEARESIN 147's soft, co-polymer film withstands milling cleanly, emerging soft and evenly broken with the finish intact. In service, the same film flexes with the leather—at the vamp of a shoe, the elbow of a garment, the fold of a bag—without cracking or delamination. This combination means finishers can mill for maximum softness and natural drape without risking finish quality, and the leather they deliver keeps performing for the customer. Very good flexing and milling properties therefore protect both process yield and end-use durability.
Excellent Anti-Yellowing Performance & Universal Versatility
SEARESIN 147 delivers excellent anti-yellowing performance and is genuinely universal, applicable as the main binder in all kinds of articles. Yellowing is the slow death of a light finish: acrylic films exposed to light, heat, and time gradually shift colour, and on white, cream, and pale shades that shift is immediately visible and commercially damaging. SEARESIN 147 resists yellowing, keeping its original clarity and shade through drying, storage, and service—making it suitable for white and light-coloured leathers as well as for dark shades where appearance stability still matters. Its versatility completes the picture: because it covers well, releases cleanly, holds print, flexes, mills, and resists yellowing, SEARESIN 147 can serve as the main binder across garment, shoe upper, bag, upholstery, and leather goods articles, reducing the number of specialty resins a finishing department must stock and simplifying recipe management. One resin, many articles—with dependable performance in each.

Application Guidelines
SEARESIN 147 is a universal acrylic binder applied as the main binder in all kinds of articles. It is widely used in the finishing of soft leathers with a natural handle and can serve as the principal film-forming resin in the base coat and intermediate coats. Because it is a co-polyacrylate dispersion with near-neutral pH and anionic charge, it is broadly compatible with conventional anionic pigments, dyes, and auxiliaries. Actual dosage depends on the specific leather type, finish system, required coverage, and desired appearance.
Typical Application Areas
• Corrected grain and buffed leather — efficient covering of substrate variation
• Embossed shoe upper and leather goods — clean plate release and sharp pattern
• Printed leather — print definition without cut-through
• Garment, bag, upholstery and general soft articles requiring natural handle
• White and light-coloured leather requiring anti-yellowing stability
SEARESIN 147 is designed as the standard main binder for finishing departments that handle a wide mix of articles. Its 30.0% solids, soft hand, strong covering power, clean plate release, and anti-yellowing stability make it efficient and predictable across substrates. Because coverage requirements vary greatly between full grain, corrected grain, and buffed leather, addition should be tuned to the specific article and finish system. SEATON technical support is available to help establish the right SEARESIN 147 loading and co-binder balance for your production.
Economic & Quality Value
SEARESIN 147 delivers practical economic and quality value across a finishing department. Very good covering power allows lower-grade, buffed, and corrected grain leather to be finished into attractive goods with lighter, more efficient coats—upgrading material value without heavy over-pigmentation. At 30.0% active substance, each kilogram delivers more film-forming capacity, reducing consumption and freight cost per hide. Good plate release cuts embossing downtime, plate cleaning, and torn or smeared leather, improving line throughput. Print cut resistance and good print definition reduce defective printed goods and rework. Very good flexing and milling properties lower cracking and peeling rejects, and protect the leather in service. Excellent anti-yellowing protects white and pale shades from colour-drift rejects. As one universal binder covering all these needs, SEARESIN 147 also reduces the number of specialty resins held in stock, simplifying purchasing and formulation. The result is a lower total finishing cost and a more consistent, higher-value finished product.
