Sumikaflex RP-100S

Type:

Ethylene-Vinyl acetate Copolymer Powder

Properties:

Sumikaflex RP-100S is easy emulsified in water. It gives

excellent performance of adhesiveness, durability and alkali
liquid resistance as well as an Ethylene Vinyl acetate
Copolymer emulsion. Due to powder, it can be pre-mixed withhydraulic powder like cement and plaster. It can also produce
for one package type material that has good construction and canbe easily treated at a field-work management.
Mainapplication:

Construction (foundation adjuster, joint materials, finishing
dressed lumber)
Civil engineering materials (vegetation)
Agrichemical spreading agent
Polymer-improved agent, high-concentrated agent for polymer
emulsion

3. Test method
SumikaflexRP-100S is easy dispersed in water at room temperature, andbecomes emulsion. In general method, it is stirred slowly with a little water first.
Next, stirred strongly and added water gradually and finally can be controlledprescribed concentration by containing water gradually.
In case of adding cement, plaster or pigment, to be sure to mix the powder
well first then add the water.
