[KDD AH1788W] Water-soluble Acrylic Resin: A Temporary Protection Solution with Medium-slow Drying Speed and Zero Water-washing Residue

Temporary protective coatings play a vital role in the storage, transportation and construction of glass, metal workpieces and high-end plastic parts. However, many traditional protective paints suffer from common drawbacks such as poor leveling caused by excessively fast drying, sticky dry films leading to stacking adhesion, as well as difficult cleaning and residual glue after construction.

Guangdong KDD launches AH1788W water-soluble acrylic resin, a functional base material specially developed to solve the above process problems. Featuring the core properties of medium-slow drying speed and excellent water washability, it provides a flexible film-forming solution for industrial temporary protection and consumer-grade easy-to-clean products.

I. Core Process Characteristics: Slow Drying, Anti-sticking and Zero Water-washing Residue

AH1788W adopts a well-targeted molecular structure and solvent system design with definite performance advantages:

• Medium-slow Drying Speed & Low Odor: The resin adopts diethylene glycol butyl ether and dipropylene glycol methyl ether as main solvents. This design delivers an eco-friendly construction experience with low odor, and endows the system with medium-slow drying performance. The moderate drying speed allows sufficient operation time for large-area coating and improves film leveling effect.

• Smooth Dry Film & Anti-stacking Adhesion: Coating anti-blocking performance is essential for workpieces requiring stacking, storage and transportation. This resin forms high-gloss and smooth paint films with excellent anti-adhesion properties to effectively avoid stacking sticking issues.

• Excellent Water Washability & Zero Residue: The core requirement for temporary protective coatings is "removable after use". AH1788W possesses outstanding water washability with no residue left on the substrate after cleaning. It is completely soluble in water and also compatible with alcohol ether solvents.
