DEGADUR® 151 AND DEGADUR® 165 FOR HIGH MECHANICAL LOAD-BEARING INDUSTRIAL AND COMMERCIAL FLOORS General Description Under the DEGADUR® trademark, Röhm produces rapidly curing methacrylic resins that are used to formulate floor coatings, with the addition of fillers and pigments. Their rapid curing (even at temperatures as low as minus 30˚C) ensures very short interruptions in routine operations. The coatings can be used to provide smooth or textured surfaces. Seamless DEGADUR® industrial floor coatings are robust and resistant to many conventional chemicals such as acids and alkalis. The degree of mechanical strength and slip resistance can be precisely adjusted according to the specific requirements or relevant industrial regulations. Individual wishes can be met in terms of color or design. DEGADUR® coating systems can generally be applied on concrete and metal substrates, asphalt, indoor and outdoor areas as well as in wet and dry rooms. Decorative systems for dry areas Coatings based on DEGADUR® 151, sealed with DEGADUR® 165, are especially suitable for easy-to-clean, decorative indoor surfaces on high-quality substrates. The DEGADUR® 165 seal coat shows particularly good resistance to chemicals and tire abrasion. Summary of benefits • Rapid curing - floor can be used and exposed to normal loads after two hours, which means minimal downtimes • Coating possible at ambient temperatures of -30˚C to +35 ˚C • Good wear resistance • Seamless and water-tight • Good chemical resistance to acids, alkalis and many cleaning agents • New DEGADUR® coatings can be applied to old DEGADUR® substrates DEGADUR® 151/165 – for custom-tailored system solutions • Extremely hard-wearing with high compressive strength • High resistance to gasoline and oil • Good resistance to tire marks • For application on substrates with high mechanical strength Fields of application • Storage rooms • Salesrooms and exhibition rooms • Bakeries, cafés, beverage stores • Laboratories, pharmaceutical industry • Printing shops, distributing centers, workshops • Discothèques, gyms • Changing

Substrate Composition The substrate must be correctly prepared for coating as described below. The primer must be allowed to cure properly on the substrate in order to guarantee a durable bond. This applies equally to concrete, asphalt and metal substrates. The surfaces must be solid, dry, offer good grip and be capable of bearing loads. They must be free from laitance, loose particles, flakiness and substances like grease, oil, rubber fines, paint residues or other contaminants that would prevent bonding. The best floor preparation is usually achieved by means of shot blasting or mechanical...

In practice, external influences may lead to deviations from these values. Coating Coatings with DEGADUR® 151 can be easily smoothed using a trowel. DEGADUR® 151 is the preferred choice for trowel-smoothed coatings of 4–6 mm...

The mixture for practical purposes is applied using a pin rake in the desired layer thickness and then smoothed with a suitable smoothing trowel. Seal Coat With trowel-smoothed colored sand coatings and smooth coatings based on DEGADUR® 151, it is essential to apply an intermediate primer layer of DEGADUR® 112 before applying the DEGADUR® 165 seal coat. The entire quantity of DEGADUR® 165 mixed with BPO powder is poured onto the coating, distributed roughly using a serrated rubber blade and then evenly applied with a mohair roller (pile 4 mm).
