MMA Resin (MR-100)
MMA resin is a soft material such as ascon. It does not peel off with the mother body (ascon and concrete) and serves to strengthen the surface. Since the curing limit temperature is -30°C, it can be constructed during the winter season and is an eco-friendly product that is harmless to the human body
Characteristics
-
Eco-friendly
a solvent free produt that is harmless to the human body
-
quick construction
It completely hardens within 30 minutes.The curability hardly changes even at low temperatures of -30°C.Short-term construction, early opening, and construction under the same conditions regardless of season.
-
Exceptional adhesive property
It adheres to the ascon.It's made of soft material, so it doesn't interfere with the shrinkage and expansion rate of the mother.It doesn't peel off and strengthens the packaging.
-
Outstanding flexibility
There are fewer cracks due to impact.No cracks in the corners
-
Weather proof
It has the best weather resistance among commonly used resins, so there is little discoloration, chocking, or embrittlement.Performance is maintained for a long time.
