PRODUCT INTRODUCTION

PM-21 is a hich-perormance two-component reinforcement penetrating primer composed of high guality epoxy resin ancCardanol-modified phenolic amine curing agent. it's low VOc, water resistance, excellent permeallity, fast drying speed, goodworkabilitly, corrosion resistance, good chemical resistance, high hardness, strong adhesion to the treated substrate

APPLICATION SCOPE

It can be used as the first primer on the surface of interior and exterior cement, concrete, metals and other surfacesIt can also be used as alkali-resistant primer for floors, sealing primer for exterior walls, and sealing primer for concretebridges, as well as other building material substrates except for plastic.

COVERAGE It covers 0.3-0.5kg/ m' per coat, depending on surface conditions. Highly porous surfaces require a second coat

POT LIFE Approx.30 minutes depends on temperature.

CURING TIME 1 hour (Touch dry),7 days (Full cure)

APPLICATION INSTRUCTION

• PM-21 must be thoroughly mixed A:B=1:2 (weight ratio) using a slow speedmixer or hand taking care to avoid introducing too much air into the mix duringmixing. Mixing should continue for about 2 minutes or until a homogeneous mixis achieved.

• Apply by roller or brush. increase the coverage rate or apply a second coat if necessary.

• Before construction, ensure that the substrates surface must be clean, dry, nooil stain, no impurities. Cracks need to be sealed.

HOW TO CLEAN Cleaned with a damp cloth with a minimum of Xylene, Acetone or Methylatedspirits.

STORAGE Stored properly in undamaged and original sealed package in dry and cooltemperature range +5℃ to +35℃, protect from direct sunlight and frost.

SHELF LIFE 12 months from the date of production
