Aspartech Long-Term Performance
By combining exceptional adhesion, high surface hardness, excellent abrasion resistance, outstanding UV stability and a Zero VOC formulation, Aspartech CLEANZONE delivers the performance expected of a premium industrial and commercial floor coating. Whether used in warehouses, healthcare facilities, food production areas, laboratories or commercial premises, it provides a durable, attractive and long-lasting finish designed to perform in the most demanding environments.
Chemical Resistance
Industrial and commercial floors are often exposed to a wide variety of chemicals during normal use, from routine cleaning products through to fuels, oils and aggressive industrial substances. A floor coating must be capable of withstanding these exposures without softening, staining or degrading if it is to provide long-term protection.
Aspartech CLEANZONE has been formulated to provide excellent resistance to many of the chemicals commonly encountered in warehouses, workshops, manufacturing facilities, laboratories, healthcare environments and food production areas. This helps maintain both the appearance and integrity of the floor while reducing maintenance costs and extending the service life of the coating.
The table below summarises the performance of Aspartech CLEANZONE following 1 hour and 24 hour exposure to a range of commonly encountered chemicals.
Aggressive Chemicals
While Aspartech CLEANZONE offers outstanding resistance to a broad range of chemicals, prolonged contact with highly aggressive substances should always be avoided where possible.
Testing showed that:
-
DOT 4 synthetic brake fluid caused surface etching after 24 hours of continuous exposure.
-
Hydrochloric acid also caused surface etching after 24 hours of continuous exposure.
Importantly, neither chemical caused visible damage after a 1-hour exposure period, demonstrating that accidental spills can generally be cleaned before any permanent effect occurs.
Good Housekeeping Practice
Although Aspartech CLEANZONE provides excellent chemical resistance, good housekeeping remains essential. Chemical spills should always be cleaned as soon as practical, particularly aggressive acids, brake fluids and other reactive substances. Prompt removal not only protects the coating but also helps maintain a safe working environment and reduces slip hazards.
Under normal operating conditions, Aspartech CLEANZONE provides a durable, hygienic and highly chemical-resistant finish that is well suited to demanding commercial and industrial environments where regular cleaning and occasional chemical exposure are expected.
Application Instructions
Proper mixing is critical in the successful application of Aspartech CleanZone. The system is supplied in two, pre-weighed components which contain the correct ratio of material for the kit. Part ‘A’ is commonly referred to as the ‘Resin’ and part ‘B’ as the ‘Hardner’.
The mix ratio for Aspartech CleanZone is 83.75% part ‘A’ with 16.25% part ‘B’. Part ‘A’ is supplied in a plastic bucket and part ‘B’ is supplied in a plastic bottle. A chalk line can be used to create application sections and ensure a consistent application depth.
❶ Ensure you have the correct number of part ‘As’ and Bs’ and the containers are sealed and undamaged. Create a defined mixing area using a tarpaulin to protect the surface of the mixing area from spills and splashes.
❷ Remove the lid from part ‘A’ and mix for 60 seconds using a drill mixer at a low-speed setting and a helix mixing paddle. This ensures that any settled colours and additives are evenly distributed back into the mix.
❸ Remove the lid from part ‘B’ and carefully pour the contents into the bucket containing the premixed part ‘A’. Squeeze the bottle to ensure as much of the part ‘B’ is added to the bucket as possible and do not replace the lid.
❹ Submerge the mixer head into the resin and start to mix on a medium speed for 60 seconds. In colder temperatures (<10°C) the viscosity of the product can increase, and it may be necessary to mix for 90 seconds. Whilst mixing, move the mixer head around the bucket, scraping the sides and bottom. Avoid mixing at an excessive speed as this can result in splashing and whipping air into the mixture.
❺ After mixing is complete, let the product stand for 60 seconds to allow any trapped air to escape. Pour the mixed resin onto the application substrate.
The mixed components have a pot-life of between 20 and 30 minutes.
Warmer temperatures (>30°C) can reduce the pot life.
Mixed resin should not be allowed to stand in the bucket for a prolonged period as the volume of the material allows for heat build-up (exothermic reaction) which can significantly speed up the rate of cure and result in roller/squeegee indentations on the cured surface.
❻ As soon as the mixed resin is poured onto the application area, use a trowel, squeegee, or roller to spread the resin over the application area. Work in predefined sections to ensure the correct application depth and avoid uneven curing. Always keep a wet edge which will prevent trowel, squeegee, or roller marks. Use a spiked roller to remove any trapped air bubbles and ensure a uniform finish.
❼ Equipment such as the mixer blade, trowels, brushes, squeegees, and rollers should be cleaned at regular intervals using Aspartech SOL-ZERO and then dried using a clean rag or fabric cloth.
Cure Time
One of the key advantages of Aspartech CLEANZONE is its exceptionally rapid cure profile. Developed using advanced resin technology, the coating has been engineered to minimise downtime while delivering outstanding mechanical performance and long-term durability. Unlike conventional epoxy floor coatings that can require several days before returning an area to service, Aspartech CLEANZONE progresses quickly from application to full cure, allowing projects to be completed faster and reducing disruption to normal operations.
Following correct mixing and application, the coating develops in a series of predictable stages:
Fast Return to Service
Under normal application temperatures of 15°C to 25°C, Aspartech CLEANZONE can typically be:
-
Tack free in just 2½ hours
-
Recoated after approximately 3 hours
-
Walked on after around 4 hours
-
Returned to heavy service after 24 hours
-
Fully chemically resistant within 7 days
This rapid cure profile makes Aspartech CLEANZONE particularly well suited to warehouses, manufacturing facilities, food production areas, healthcare environments, retail premises and commercial buildings where downtime must be kept to an absolute minimum.
Important Guidance
The cure times shown are intended as a guide only. Actual curing performance will vary depending on substrate temperature, ambient temperature, relative humidity, coating thickness and site ventilation.
Cold concrete substrates can significantly extend cure times, even where the air temperature appears suitable, while warmer conditions will generally accelerate the curing process.
For the best balance of application time, finish quality and curing performance, Aspartech CLEANZONE should ideally be applied at 17°C onto a clean, dry and suitably prepared substrate.
Coverage Rate
The recommended application thickness of Aspartech CLEANZONE depends on the intended service conditions and the condition of the substrate.
● Light foot traffic: Minimum dry film thickness of 0.7 mm
● General commercial and industrial use: Minimum dry film thickness of 1.0 mm
● Heavy traffic or demanding environments: Minimum dry film thickness of 1.2 mm
Coverage rates are dependent upon the specified application thickness together with the texture and porosity of the substrate. Smooth, well-prepared concrete will provide the highest coverage, whereas textured or porous substrates will naturally require more material to achieve the same film build.
Typical coverage rates at >0.7mm depth are:
Aspartech CleanZone 20kg: Smooth surface=21m² Textured surface=19m² Porous surface=17m²
Aspartech CleanZone 5kg: Smooth surface=5.25m² Textured surface=4.5m² Porous surface=4.25m²
Theoretical Coverage on Smooth Surfaces
For suitably prepared, smooth substrates, the theoretical coverage is determined primarily by the application thickness.:
Aspartech CleanZone 20kg: 0.7mm=21.9m² 1.0mm=14.76m² 1.2mm=12.3m²
Aspartech CleanZone 5kg: 0.7mm=5.27m² 1.0mm=3.69m² 1.2mm=3.08m²
The figures above are theoretical values based on the mixed density of the product and assume application to a smooth, non-porous substrate. Actual coverage will vary depending on substrate profile, surface porosity, wastage and application method.
