Obstacles with low VOC gloss/semi-gloss Systems
In architectural paint applications, there is a challenge for suppliers and paint producers to meet environmental regulations while offering acceptable quality products to customers.
Finding a balance between lower VOC products and maintaining important film properties can be challenging.
Primary VOC sources are coalescents and freeze thaw agents. To combat these VOC levels, many companies started formulating using polymers with Tg (glass transition temperature) of 0 to 5°C to form a paint films with zero or minimum levels of coalescents.
However these soft polymers have some shortcomings for freeze thaw and block resistance.
ANGUS products AMP™ Co-dispersant and Neutralizing Amine and AEPD™ VOX 1000 Multifunctional Amine can help reduce full VOC freeze-thaw/open time agents and dispersants while meeting formula performance criteria for block & freeze thaw resistance. To learn more, refer to the charts above for additional information.

Odor Concerns
Several factors, in terms of odor, can play a role in a formulator’s choice when choosing raw materials to incorporate into a paint system.
Some of these include:
- Personal Perception
- Industry Driving Factors- Volatile Organic Compounds (VOC) Regulations
- Raw material Consolidation-Database
- Complaints- Manufacturing &/or Customer
To reduce odor in paint formulations, paint manufacturers are demanding non/low VOC raw and materials. AMP can help to reduce full VOC freeze thaw/open time agents and dispersants to lower odor in paint formulations. In addition AMP has lower odor than the benchmark Ammonia.
The newest product from ANGUS, AEPD VOX 1000 (XZ 12322.00 in North America), however is considered a VOC-free in Asia Pacific and Europe and a low-VOC product in other areas of the world. This product has similar functionality to AMP, but with the added benefit of having less odor and lower VOC. It is currently being used commercially in leading odorless paint.
