LEVL Coat 551 — polyurethane binder for rubber crumb coatings
LEVL (INGRI)

LEVL Coat 551 — polyurethane binder for rubber crumb coatings

Sports grounds, playgrounds, running tracks and courts are covered with a resilient layer of rubber crumb or EPDM granules bound with LEVL Coat 551. The one-component solvent-free polyurethane gives a monolithic, water-permeable, non-slip and injury-safe coating resistant to abrasion and impact. The mix is laid by hand with a trowel and compacted with a roller over LEVL Coat 151 primer; the binder is also suitable for making crumb rugs, mats and tiles, and as an adhesive. Packaging: 15 kg pail and 225 kg drum.
