MMA Seamless Bridge Deck Waterproofing Coating
MMA Description: 
Waterproofing coatings for concrete bridge deck have embraced an unprecedented opportunity with the rapid development of high-speed rail. Nearly all high-speed rails adopt concrete bridge structure, and the purpose of bridge deck waterproofing layer is to ensure and improve the durability of bridges. Water infiltration is inclined to lead to freeze-thaw damage, corrosion of reinforcing steel, concrete alkali-aggregate reaction... So, bridge deck waterproofing is urgent.
 
ELASUREA-MMA is developed specially for the protection of bridges in inter-city railway and high-speed railway. With its high strength, strong adhesion, super weatherability, easy applied, high elongation..ELASUREA-MMA has earned enviable market and reputation.
 
MMA Advantages :
 Ultra fast cures fully in no more than 2 hours at -40ºC. Minimum downtime, high application speed, people can walk after 1 hour
 
 Creates a totally seamless surface without pinholes or air bubbles which could affect its waterproofing performance. Protect substrates perfectly
 
 Highly resistant to UV, weathering and temperatures up to 80ºC. Capable of withstanding most industrial environments
 
 Excellent resistance to physical and chemical attack. Durability, long service life
 
 Elastic and won't shrink. Resistant to cracking, wear, impact, puncture.
 
 100% reaction and no organic solvent 
 
 Cost effective
 
Where to use:
 Concrete bridge deck
 Stell-structure bridge deck
 Bridge pier
 Pipe
 Industrial flooring
 Roofing
