polyaspartic direct to metal coating machinery coatings

PolyasparticDTM (PolyDTM) is on the leading edge of easy to use, rapid curing, direct to metal (DTM) polyaspartic coatings. It meets both current, and potential future, VOC requirements while retaining the desired fast return to service attributes that end users have come to expect from polyaspartic coatings.

PolyDTM can be applied directly to properly prepared steel, aluminium, galvanized steel or concrete as well as to existing coatings such as epoxies and urethanes as recommended.
Even though PolyDTM is designed to be DTM it’s even better over our Blast Saver Primer (BSP) which removes many prep question marks and is indefinitely recoatable. Removing any fear of corrosion taking hold before PolyDTM can be applied.

Ten years ago, polyaspartic DTM coatings were considered a light to medium-duty solution for a particularly niche portion of protective coating applications. Now however, after over a decade of in-field use and advancements in formulations polyaspartics are a proven technology with demonstrated long-term performance. 

PolyasparticDTM Key Features:

  • 4x higher abrasion resistance than epoxy products
  • Non-yellowing, complete UV stability
  • High gloss, glass like shine
  • Chemical, and highly corrosion resistant
  • Suitable for water immersion
  • Low viscosity
  • Solvents: 0
  • VOC (g/l): 0
  • Cures at temperatures just above Freezing
  • Dual-curing technology: Moisture + Chemical
  • Further enhanced corrosion resistance when paired with Blast Saver Primer
  • Easy mixing ratio (1:1)

Preparation 

Steel

Ensure all rough welds, sharp edges and weld spatter are smoothed or removed. Remove any grease, oil and other contaminants in accordance with AS1627.1. Abrasive blast clean to a minimum of AS1627.4 Class 2.5. Remove all dust and loose contaminants post blasting by brushing or compressed air, and vacuum cleaning.
Where abrasive blast cleaning is not viable: Rust, mill scale, oxide deposits and delaminating paint films must be removed by power tool cleaning according to AS1627.2. If this is also not viable use Blast Saver Primer.
Blasted surfaces should be coated within 8 hours after blasting or before rusting or other contamination of the surface occurs. If this is not possible use Blast Saver Primer, PolyasparticPS can then be applied in any amount of time required once the primer is dry.
For best results and enhanced corrosion resistance always apply Blast Saver Primer followed by PolyasparticPS 2 coats at 150 micron WFT per coat. 

Concrete

Concrete should be at least 28 days old before coating. Remove all laitance, release agents, curing compounds, oil, grease, failing coatings, dust, dirt and other surface contaminants. Fill any large cracks or voids using Epoxy2U Polyurea Crack Repair or other suitable approved filler. The surface should be profiled via diamond grinding or shot blasting to ensure maximum adhesion. Moisture content of the slab should be below 5%, otherwise a moisture vapor barrier, such as Epoxy2U MVB15 should be applied prior to the Polyaspartic PS coating. 

Existing Coatings

For best results use Blast Saver Primer. Test adhesion of existing coating by standard cross hatch adhesion test. If the coating fails, it must be removed. Clean the surface to remove any chalking and dust. If the coating is not weatherd and outside its recoat window you may need to mechanically abrade the surface to provide a key for the new coating. For best results use Blast Saver Primer on painted surfaces prior to PolyasparticPS.  

Coating performance is directly proportional to the comprehensiveness of surface preparation. 

Application

Recommended application is by 1:1 plural component sprayer such as Surface Engineering Equipment PSM11, Graco XP70, or similar capable of 80 - 140 psi at the spray tip. Use the lowest pressure possible to achieve the desired finish. Work methodically and allow adequate overlap of each pass. Do not spray an area that will take over an hour to complete before you are able to return to the starting point and begin the next coat. This ensures the first layer is within its recoat window to achieve maximum intercoat adhesion.
The reason plural component application equipment is recommended is to eliminate pot life issues from the rapid curing nature of the product and to minimise waste. Contact an appropriate equipment manufacturer for a recommendation.
This product is designed to be applied by professional trained coating applicators familiar with the application of airless, plural spray, and multi-component products.
Thinning is not required. Heating is usually not required but can be utilised at the applicators discretion.

Note: where one coat is normally required; certain colors may require additional coats to achieve full depth of colour. 

Safety

Read the PolyasparticDTM MATERIAL SAFETY DATA SHEET and any precautions on container labels before applying. MSDS are available from www.epoxy2u.com, www.epoxy2uaustralia.com, or by contacting info@epoxy2uaustralia.com
Keep containers closed at all times when not in use.
As with any coating; ingestion, inhalation and prolonged or repeated skin contact should be avoided by utilising good work safety practices.
Eye protection approved to AS1337 should be worn where there is a risk of splashes entering the eyes.
Always wash your hands before smoking, eating, preparing food for others, drinking or using the toilet.
Use in an area with good ventilation and avoid inhalation of atomised coatings. If risk of inhalation of coating particles exists, wear a cartridge type combined organic vapour/particulate respirator or supplied air system. When spraying, users must comply with the spray painting regulations in their country/state. In confined spaces workers must wear fresh airline respirators and comply with relevant safety regulations for working in confined spaces in your country/state.

This product is not flammable.

If welding coated surfaces, first grind off coating before welding. 
CAUTION: Read and follow all caution statements on this product data sheet and on the Material Safety Data Sheet for this product.  

Shelf Life

Shelf Life: 2 years unopened for both the Part A and B when stored inside out of direct sunlight at between 5C - 45C (40°F to 110°F). Use opened containers as soon as possible. Never leave containers open longer than is necessary.
