Versatile Functional Additives
The Versatile Functional Additives we've worked on
VeryPaint® Versatile Functional Additives include waterborne crosslinkers, hand-feel agents, leveling agents, defoamers, polyethyleneimine (PEI), and anti-stain additives, designed to improve both performance and formulation efficiency.
They are widely used in coatings, inks, adhesives, textiles, and industrial applications, helping enhance adhesion, surface smoothness, and film quality while reducing defects such as bubbles and poor leveling. These additives also provide functional benefits like improved durability, anti-fouling properties, and better surface feel, enabling more stable production and consistent results.
Aziridine Crosslinker
- Product ID: FA-1211
- Appearance: Clear transparent liquid
- Solid Content: >99%
- Viscosity: 100–500 mpas
- pH: 9-11
FA-1211 is a high-efficiency aziridine crosslinker with 100% active content and excellent water solubility, specifically designed for waterborne coating systems. It reacts readily with functional groups such as carboxyl (-COOH) in acrylic, polyurethane, and other resin dispersions, forming a dense three-dimensional crosslinked network. This significantly enhances the overall performance of the coating while maintaining the advantages of low-VOC, environmentally friendly formulations.
Polyethylenimine PEI
- Product ID: PEI-25000
- Appearance: Colorless to light yellow liquid
- Solid Content: ≥99%%
- Viscosity: 200,000 – 350,000 mPa·s
- pH: 10-12
Polyethylenimine (PEI), sometimes called polyaziridine, is a special type of water-soluble polymer known for its very strong positive charge. Its structure is built from simple repeating units made of carbon and nitrogen, forming a flexible and highly reactive chain. PEI-25000 is a medium molecular weight grade (around 25,000), appearing as a colorless to light yellow viscous liquid with a slight ammonia-like odor.
