In the design of aqueous polymer formulations, many customers encounter a typical contradiction: the system needs certain acidic functional groups to enhance stability and adhesion, but traditional acidic monomers can easily harden the final polymer film, affecting flexibility, adhesion balance and film formation performance.

SIPOMER^® BCEA is designed to address these kinds of problems.

It is an APE-free specialty functional monomer suitable for adhesives, glues, and coating systems. It introduces carboxylic acid functional groups into copolymers, while helping to improve latex stability, enhance adhesion, and reduce the risk of "overly hard films" associated with traditional acidic monomers. For customers developing modern waterborne systems, this is a raw material choice that balances functionality and formulation.

Why choose SIPOMER^® BCEA?

The true significance of SIPOMER^® BCEA in formulation

Many water-based formulations require acidic functional groups because they affect emulsion stability, interfacial adhesion, and system tuning capabilities. The problem is that while some common acidic monomers can provide functionality, they can also make the resin system too stiff, thereby affecting flexibility, wettability, or film balance.

The value of SIPOMER^® BCEA lies in:

It not only provides acid functionality, but also strives to maintain a more balanced film-forming performance.

This means that it is not simply "adding a monomer", but rather helping formulation engineers to more easily balance and stabilize the system and create products that better meet end-user requirements.

Suitable Applications

SIPOMER^® BCEA is particularly suitable for the development of waterborne polymers and resins, especially in the following scenarios:

Solution

1. Solutions for PSA pressure-sensitive adhesives

The most common pain point for pressure-sensitive adhesive customers is:

They want to improve adhesion, but they don't want the adhesive film to become too hard. Many traditional acidic monomers, while increasing functionality, can cause the system to lose flexibility and balance, affecting initial tack, peel strength, and wetting performance.

The advantages of SIPOMER^® BCEA are that it combines acid function, improved adhesion and emulsion stability, while also being more conducive to maintaining a softer film characteristic.

Therefore, it is particularly suitable for:

• Water-based pressure-sensitive adhesives

• Label adhesives

• Tape adhesives

• Flexible adhesive systems

2. Solutions for water-based coating resins

For manufacturers of architectural coatings and protective coating resins, raw materials must not only be functional, but also stable and balanced in application. If a monomer can improve adhesion but makes the paint film too hard and brittle, the subsequent application effect will often be limited.

SIPOMER^® BCEA is more accurately described as a “balanced waterborne resin monomer”.

While introducing carboxylic acid groups, it avoids the hardening tendency common in some traditional acidic monomers, making it more suitable for customers who require adhesion, stability and film-forming properties.

Especially suitable for:

• Architectural and Protective Coatings

•  Waterborne Industrial Coatings

• High-Performance Acrylic Binders

•  Polymer Systems Requiring Emulsion Stability
