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.

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.

Feature

A simple process enables advanced dispersion and filler stabilization.
