Sikafloor-390 N
Tough-elastic crack-bridging coloured epoxy floor coating
Product Overview
Sikafloor-390 N is a two-component, solvent-free, tough-elastic coloured epoxy resin used as a self-smoothing or roller coating on concrete and cementitious screeds in production and processing areas. Mixed at 85:15 by weight at about 100% solids, it applies at roughly 1.6 kg/m2 per millimetre and cures to a seamless surface combining abrasion resistance, chemical and decontamination resistance, and crack-bridging to around 0.2 mm. With about Shore D 60 hardness and adhesion above 1.5 N/mm2, it can be finished gloss or slip-resistant for interior and exterior use. Its toughness suits floors that experience both wear and minor structural cracking. Space Arc Engineering, an authorized Sika distributor in India, supplies Sikafloor-390 N along with matching primers and seal coats.
Features & Benefits
- Tough-elastic formulation bridges cracks up to about 0.2 mm
- Abrasion-resistant surface withstands traffic and mechanical wear
- Chemical and decontamination resistance suits demanding process areas
- Solvent-free, ~100% solids build for an efficient seamless layer
- Gloss or slip-resistant finish options for varied environments
- Suitable for both interior and exterior floors with strong adhesion
Technical Highlights
| Coverage | About 1.6 kg/m2 per millimetre for the wearing layer; 0.75-0.85 kg/m2 for seal or top coat on broadcast systems. |
| Strength | Shore D hardness about 60 (14 days); flexural strength ~10 MPa; adhesion above 1.5 N/mm2 (concrete failure). |
| Performance | Crack-bridging (~0.2 mm), abrasion-resistant, chemical- and decontamination-resistant seamless epoxy floor. |
| Application Conditions | Apply at +10 C to +30 C, maximum 80% relative humidity; pot life about 30 minutes at +20 C. |
| Packaging | Supplied as 25 kg ready-to-mix units (Part A 21.25 kg + Part B 3.75 kg). |
Applications
- Production and processing plants with floors prone to fine cracking
- Warehouses and logistics floors needing abrasion-resistant coatings
- Food, beverage and chemical facilities requiring decontaminable surfaces
- Workshops and engineering bays exposed to mechanical and chemical stress
- Exterior service areas and platforms needing tough, seamless protection
