 Double Units Polyurethane Liquid Membrane

DYC-932,two-component  environmentalfriendly polyurethane waterproof coating, as a result of  reaction of two components, A and B, is a  reacting waterproof coating. By composition of component A and B,component A is  the polyurethane prepolymer which is composed by esserbetol and diisocyanate.  The B component is viscous liquid which contains perssad OH, such as  surfactant, filler,curing agent, catalyst. When using, mix component A and B,  according to a certain weight ratio.Hours later, elastic,tenacious,durable waterproof  coating layer comes into being.
 alant  to roll material close up and divider seam around pipeline.

 Features
 High  strength, good elongation rate, high solid content, strong adhesive.
 Good  machanical property, stable weather resistant ability.No coal tar, safe and  environmental friendly.
 Good  adaptability to substrate deformation, easy install for complex surface  transition.

Construction Method
 1. It’s necessary to clean the  dust, sand material, mortar, lumps and other debris before the construction.
 2. The base surface should be dry,  smooth, non- porous, sand or cracks. Cracks need to be filled by cement mortar.
 3. When use,we mix component A and  B at certain proportion, and being stirred well. One time stirred coating  should be used within 2 hours. After fully dry, it can be painted again. The  direction of second time painting needs to be perpendicular to the first time  painting. Make the film uniform, and the joint and angle should be construction  according to the design requirement.
 4. The brushed waterproofing layer  should be protected by the cement mortar in time.
 

Construction Attentions:
 1. Mix component A and B as the  package’s proportion and stirred it well, it should be used out within 2 hours.
 2. After fully dry, it can be  constructed again.
 3. Construction in cloudy days is  strictly prohibit, it can not contact with the rain before fully dry .
 4. The temperature for application  should be 5~35℃.
 5. The base surface should be dry  in the underground construction, and it should be constructed after 24 hours of  the drain process.
