✓ Premium Strength - 1.79MPa crushing resistance
Product Introduction
The North of China Metro Challenge
When engineers needed to clad -30°C subway stations with 1200x600mm porcelain, standard adhesives cracked under thermal stress. Zrete C2 delivered:
1.41MPa heat-aged strength (+41% vs spec)
0.3mm max movement under thermal cycling
Zero tile replacements after 3 winters
Engineer-Centric Formula
Micro-silica enhanced polymers create:
Flexible crystalline networks accommodating tile expansion
Rapid moisture regulation preventing frost damage
Vertical grip matrix eliminating slip on large formats

Product Usage
The Arctic Test
When North China engineers faced -28°C coastal winds while cladding a glacier museum, standard adhesives failed. Zrete C2 delivered:
1.14MPa bond strength after 100 freeze-thaw cycles
Zero tile displacement in 80km/h winds
40% faster installation vs polymer-modified adhesives
Science of Superiority
Patented micro-silica technology:
Creates flexible crystal matrices accommodating tile expansion
Self-regulates moisture to prevent ice damage
Vertical grip network eliminates slip on jumbo slabs
