SUMAN REFRACTORY Vinyl Ester Mortar
SUMAN REFRACTORY Vinyl Ester Mortar is used in the construction of floors, sumps, trenches, tanks, vessels and bleach towers in chemical processing, food and beverage plants, dairies, laboratories, textile, steel and pulp & paper mills.
SUMAN REFRACTORY Vinyl Ester Mortar has excellent resistance to oxidizing bleach solutions, mineral and organic acids, alkaline solutions and some organic solvents. When used with chemical resistant masonry units and the proper membrane Vinyl Ester Mortar will protect concrete and steel sub base from chemical attacks and physical abuse.
Resistant

130° C (Max.)
Preparation of Mortar
Vinyl Ester Mortar is silica filled vinyl ester mortar is in two component – powder & liquid – which must be mixed together in the proper proportions (1:5.5 PBW) prior to usePrepare small batches of Mortar. Stirrer the Solution thoroughly before use. Place the Solution in a suitable mixing pan and add powder in it. Mix thoroughly with a spatula or Trowel. The mixing operation shall be continued until a uniform mixture is obtained.
Make sure that all the Mortar is used from the mixing pan before another batch is prepared.
Surface Preparation
The cement plastered surface shall be slightly rough in line & level, dry & clean, free from dust, dirt, grease, oil etc., maintaining required slope etc. as no slope can be adjusted or altered in Acid proof lining works.
