Ressi EPO Primer
An epoxy-based Primer to be used prior to the application of epoxy flooring and coatings over concrete and cementitious surfaces. This material comprises of bisphenol A based Resins and a modified polyamide-based hardener designed to maximum strength and abrasion resistance. Typical areas of application include car parks, factory floors, food industry, kitchens, aircraft hangers, hospitals, pharmaceutical plants, warehouses etc. it can be used as a clear to golden coat to maintain original color and appearance of substrates which are not exposed to UV rays.
Ressi EPO Primer is an epoxy-based Primer to be used prior to the application of epoxy flooring and coatings over concrete and cementitious surfaces. This material comprises of bisphenol A based Resins of maximum solids and a modified polyamide-based hardener designed to maximum strength and abrasion resistance. Ressi EPO Primer is an ideal material to be used in conjunction with various epoxy flooring materials. It is used as a priming coat on concrete and cementitious surfaces prior to the application of various epoxy floorings and coatings. Typical areas of application include car parks, factory floors, food industry, kitchens, aircraft hangers, hospitals, pharmaceutical plants, warehouses etc. It can be used as a clear to golden coat to maintain original color and appearance of substrates which are not exposed to UV rays. Ressi EPO Primer is also suitable for a variety of materials such as metal, wood, ceramic, concrete, textile, glass, leather etc.
ADVANTAGES
- Provides an excellent key for the topcoat of epoxy floorings and coatings.
- Early development of initial hardness minimizes maintenance disruption.
- Excellent resistance to absorption and impact.
- Unaffected by a wide range of acids, alkalis, and industrial chemicals.
SURFACE PREPARATION AND MIXING
Surface should be free from grease, oil chemical contamination, dust, laitance and loose concrete. This can be achieved by scabbing or light brush hammering to provide a soundsubstrate. Ressi EPO Primer is supplied in premeasured two-part containers. Mix the premeasured quantities as per the ratio with a high-speed drill mixer fitted with a paddle. The material is to be mixed thoroughly until homogeneous.
APPLICATION
Apply the material with a suitable squeegee, stiff nylon brush or roller working the Ressi EPO Primer into the substrate to ensure total absorption into the pinholes and voids. Spray application is also possible. Airless spray will provide faster rate of application.
