High Build Solvent Free Epoxy
High Build Solvent Free Chemical Resistant Coating
301CRSG is a high performance solvent free coating designed for aggressive environments.
301CRSG is based on a special liquid epoxy polymer reacted with a blend of amine and polyamino resins reinforced with inert pigments and silicas which produces a system with exceptional mechanical, chemical and corrosion resistance.
301CRSG offers excellent adhesion to steel and concrete and has outstanding abrasion and erosion resistance making it ideal for tanks, containment areas, steelwork and floors.
Before proceeding, please read the following information carefully to ensure that the correct application procedure is fully understood.
Steel Surfaces – Surfaces should then be abrasive blast cleaned to a minimum Sa21⁄2 – Sa3 BS7079 Part A1 : 1989 or equivalent with a blast profile of 75 – 125 microns corresponding to ‘Rough’ in ISO 8503/1. All loose abrasive dust and debris must be blown clear or vacuum cleaned away.
Steel surfaces do not require priming but should be coated within 4 hours of blast cleaning to prevent rash rusting.
Concrete Surfaces – All concrete to be coated should either be lightly abrasive blast cleaned using wet or dry abrasive techniques or alternatively high pressure water jetting. Care must be taken not to expose the aggregate in the concrete. All dust and abrasive material shall be removed from the surface prior to coating.
312CRX is a two component material comprising base and activator components which must be mixed together prior to use.
Stir the contents of the base component, continue stirring and gradually add the total contents of the activator container, stir the combined mix until completely homogenous.
The mixed materials should be used within 25-30 minutes of mixing at 20°C (68°F). This time will be reduced at higher temperatures and extended at lower temperatures.
Application should not be carried out at temperatures below 5°C nor when relative humidity exceeds 85% or when the surface to be coated is less than 3°C above the dew point.
301CRSG is suitable for application by brush or roller, using good quality brushes or short to medium pile rollers.
On concrete surfaces it is important to stipple the 301 into the primed surface to ensure good wetting of the surface. Technology at work for you
