AAEM Acetoacetoxyethyl Methacrylate Product Description

AAEM(Acetoacetoxyethyl Methacrylate) is one of the most important products in Shenzhen Prechem's portfolio of acrylates, designed to improve the performance of acrylic polymers in coatings and adhesives. Especially for the requirements to improve adhesion, reduce glass transition temperature (can improve the elasticity and toughness of the coating), reduce the viscosity of the system (especially for high solid content system) and improve the cross-linking density has a very good effect. It also improves the adhesion of coatings to metal, ore and wood surfaces.

Compared to the solvent system, the water-based system provides us with a more environmentally friendly and healthy alternative. However, water is more difficult to fully evaporate from the system than other organic solvents. Therefore, water-based systems reduce the drying time of the coating by increasing the solid content as much as possible. Unfortunately, most high solids systems also have very high viscosity, which makes it very difficult to operate. The addition of AAEM reduces the viscosity of the acrylic polymer system, allowing the builder to easily use a water-based system with zero solvent volatilization.

The addition of AAEM helped improve the durability and toughness of water-based polymers, which, when cured at room temperature, tend to have intrinsic performance deficiencies compared to solvent systems, such as durability and toughness, and significantly improved scratch resistance and dust adhesion.

The enhanced adhesive properties make it ideal for use as adhesives and sealants in acrylic systems. Especially for applications in the field of architecture. And where high adhesion is still required under high humidity conditions.

AAEM Acetoacetoxyethyl Methacrylate Product Features

--- It can achieve low viscosity and high solid content system, less volatilization and faster drying speed.

--- Low Tg, can improve the toughness and elasticity of resin.

--- Chelation can improve the bonding properties of different substrates including metals and improve corrosion resistance.

--- Cross-linked paints, adhesives and sealants:

Better water resistance (improved bonding)

Lower dust adhesion

Better chemical resistance (e.g., cement)

Improve the surface hardness of material (high mechanical properties)

Improved scratch resistance
