Description
Staroxy NPE100 clear is a novolac epoxy system for concrete and other hard substrates where aggressive chemical spillages occur and where high wear resistance is required. Supplied as a clear binder, Staroxy NPE100 clear used neat as a clear coating system or added to a variety of fillers to produce various application systems, su trowel floor.

A non-slip finish can be obtained to a desired result by the use of any of the Parchem non-slip aggregates applied between two coats of the clear coating system.

When sealing joints in floors coated with Staroxy NPE100 clear, a purpose formulated chemically resistant joint sealant should be included as part of the overall protection system.

Parchem offers a technical support package to specifiers, end-users and contractors, as well as on site technical assistance.

Application Instructions Preparation Concrete substrates All concrete should be sound, clean, dry and free from contaminants. Hydro-blasting, captive shot blasting or grit blasting equipment is necessary to ensure that adequate substrate preparation is achieved. Concrete substrates should be blasted with either high pressure water (<3000psi) or steel shot to remove the weak surface layer from the concrete and vacuum cleaned prior to the application of Staroxy NPE100 clear. In bund areas or where uneven substrates are being experienced, wet sand blasting and

Priming All substrates on completion of the preparation are to be primed with Staroxy NPE 100clear binder or to provide a minimum wet film thickness of 150 microns. More than 1 coat may be required depending on the porosity of the substrate. When using the clear coating system, the first coat acts as a primer coat. When high build applications are required on vertical upturns or overhead, seeding the wet primer with a suitable clean grit will prevent the screed coat from sliding and provide an additional mechanical key.

Mixing and Placing:

Clear Binder Using accurate measuring jugs, add 1.5 litres of base resin to every 1.0 litre of hardener into a suitable mixing vessel. Accuracy is essential to ensure the product is mixed in ratio to achieve the required cured properties. Mix thoroughly for a min of 3 minutes using a slow speed mechanical stirrer and a suitable spiral epoxy mixing paddle.

Clear coating:

Mix the required quantity as per Clear Binder instructions without the addition of fillers. IMPORTANT: Once mixed the product should be poured into flat, open paint trays to maximise pot life working time. Holding the product in the original mixing can will lead to an exothermic reaction which will significantly reduce the pot life.

Apply first coat by brush or roller at 4- heavier if a slip-resistant grit is to be used. When using a slip resistant aggregate broadcast chosen aggregate onto the still tacky first coat at required rate. When the first coat is hard (typically next morning – refer Properties section) sweep off excess grit (if applicable) and re manner. It is recommended to apply the second coat at r angles to the first.

Storage & Self Life:
It has a shelf life of 36 months if kept in a dry store i n the original, unopened pack. Refer to the Use by Date indicated on the packaging.Store in dry conditions between 5°C and 30°C away from sources of heat and naked flames, in the original, unopened packs. If stored at high temperatures the shelf l reduced.

Handling & Safety
Keep the containers tightly sealed when not in use. Avoid skin contact and inhalation of fumes (if any). While spraying it is advised to wear a mask. If it comes in contact with the body, wash affected parts of plenty of water. In case of persistent irritation, contact a physician.
