Titanate and aluminate Coupling agent PLENACTTM
What is PLENACTTM?
PLENACTTM is a general term for Ajinomoto Fine-Techno's coupling agents, which are classified into titanate and aluminate types.
Modifying the inorganic filler surface with PLENACT improves the affinity with the organic matrix.
It is used in a variety of fields, such as improving viscosity when adding filler and improving mechanical properties of resin materials.

Titanate and aluminate coupling agents PLENACTTM
Application
Improvement of filler dispersion and adhesion to various engineering plastics
Improvement of mechanical properties of composite materials
Benefits of introduction
It bonds chemically to the surface of inorganic materials at room temperature to form an organic film.
Unlike silane coupling agents, hydrolysis is not necessary for processing.
It is very useful for improving dispersibility, adhesiveness, and flexibility in composite materials, and in improving flowability. It is used in various applications.
