AAEM Acetoacetoxyethyl Methacrylate as Adhesive and Sealant

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.

AAEM(Acetoacetoxyethyl Methacrylate) is a methacrylic ester monomer with a reactive methylene group. Provides improved mechanical and solvent resistance against water or organic solvents. Exhibits good weatherability, hydrolytic stability, low water absorption and low viscosity. It crosslinks with primary aliphatic diamines, formaldehyde, isocyanates, metal ions and activated double bonds (Michael-addition), at room temperature. AAEM can be used with acrylates and styrene acrylates in water-borne dispersions for wood, industrial and top coatings.

The enhanced adhesive properties of AAEM make it ideal for use as adhesives and sealants in acrylic systems. Especially in the field of construction applications, and some in high humidity conditions still require high adhesion.

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
