POLYWAX™
The combination of controlled branching and low MW distribution and low melt point distribution inherent to the POLYWAX™ copolymers provides many attractive benefits for formulators.

Coatings
NuCera waxes are the key to coatings that go on smooth and last longer. You can count on the high purity and on-purpose production quality to enable the following in industrial, waterproofing, inks & can coatings:
- Linearity & high crystallinity for improved slip, high chemical resistance, and excellent heat stability.
- Higher Rub resistance for better appearance and easy cleanability in ink systems.
- Improved scratch resistance & reduced mar, along with a matting effect
- Products which are FDA indirect food contact approved
- More control for formulators due to well defined melt points
