Product Description
What is CEMIMAX A390?
CEMIMAX A390 is a modified polyacrylate-copolymer dispersion adhesive designed for bonding resilient synthetic floor and wall coverings in interior applications. It provides very high initial tack, strong final bond strength, and low VOC emission performance for commercial installations. CEMIMAX A390 forms a reinforced polymer bonding layer that maintains adhesion under mechanical load and foot traffic exposure.
Where is it Used?
- Rubber flooring sheets
- Homogeneous PVC flooring
- Soft PVC floor coverings
- Vinyl tile systems
- Cushioned vinyl coverings
- Textile-backed resilient flooring
Key Performance
- Very high initial tack (10–20 min)
- Strong final bond (5–7 days)
- High coverage (300–400 g/m²)
- Low VOC formulation
- Early handling (2-hour set)
- Cohesive strength & flexibility

How is CEMIMAX A390 Applied?
Apply CEMIMAX A390 evenly using an A2 or A3 toothed trowel after thorough stirring. Follow these application steps:
- Ensure substrate is dry, clean, and smooth.
- Apply adhesive uniformly across the surface.
- Allow 10–20 minutes open time.
- Position flooring material carefully.
- Press firmly using a roller to ensure full adhesive transfer.
Curing and Strength Development
CEMIMAX A390 dries within approximately 30 minutes under normal conditions (20 °C). The adhesive sets to light traffic after 2 hours and achieves structural bonding performance after 5–7 days.
Storage and Handling Conditions
Store CEMIMAX A390 in sealed containers protected from frost and direct sunlight. Maintain storage and application temperatures above +5 °C. Shelf life remains stable for a minimum of 12 months.
