Introduction

PECORA A-103 Mastic is an asphaltic, fibrous, chemically resistant trowel-consistency material.  It is recommended as an acid-resistant coating applied between the brick work and metal shell of towers and pump tanks.

PECORA A-103 Mastic sets up to a firm but elastic film.  It is sometimes used on its own but more often with an acid resistant membrane such as PTFE film or Rephanol ORG.
