EPOXY ACRYLATE ADHESIVE FOR NATURAL AND ARTIFICIAL STONE
Iridum is a styrene monomer epoxy acrylate-based adhesive. It is recommended for bonding artificial and
porcelain marbles. Its consistency also makes it ideal for plastering and shaping.
Its characteristics are:
• EXCELLENT ADHESION ON NATURAL AND SYNTHETIC STONE, PORCELAIN STONEWARE,
TECHNICAL CERAMICS (DEKTON, LAPITEC, LAMINAM, ETC.)
• QUICK HARDENING
• EXCELLENT SURFACE DRYING

• Catalyst percentages greater than 3% may cause adhesive to yellow.
• Catalyst percentages less than 1% and at very low temperatures may extend hardening times.
• Thickened or partially gelled adhesive must not be used.
• Adhesive should be applied as thinly as possible to limit shrinkage and exothermic heating during polymerisation.
• Excessive exposure to sunlight may cause adhesive to yellow.
• After hardening, the adhesive cannot be removed with solvents. It must be removed mechanically.
