Applications
Coating agent for paper containersAdhesive agent for paper packagings
The coating layer is excellent in water resistance,therefore, penetration of water
is suppressed on the paper.
Adhesion
The coating layer has excellent adhesion tovarious substrates including paper.

In recent years, 'Plastic-free' is a trend word. Among them, 'Paper' is attracting attention as alternative materials to plastics for disposable. We propose the water based coating agents for the paper substrares that can be used well by making use of dispersion formulation technology that Unitika has cultivated over many years. Utilizing the unique properties such as adhesion, water and chemical resistance etc., Unitika coating agents improve the paper performance. We will contribute to spread and expansion of paper substrates by our coating agents.
