Sodium Silimor Mortar
Sodium Silicate Mortar is widely used for Acid Resistant Bricks & Tiles lining works as Bedding & Jointing Mortar for Tanks, Floor, Drain, Foundation etc.
Resistant to:
- Sodium Silicate mortar are useful in PH range of 0-6 except where sulphuric acid exporser existing in the vaper phase wet-dry exposures or in concentration above 93% It is also resistant to Oxidizing & Non-oxidizing Acids, & except Hydrofluoric Acid & Water.
Resistant to temperature :
- 1000° C (Max.)
Preparation of Mortars:
- Preparation of Mortar generally consists of Solution & Powder. In order to obtain good working consistency, the average mixing ratio is 1 Pbw of Solution & 3 pbw of Powder. This ratio will slightly vary depending upon the temperature and working conditions.
- Prepare 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.
Setting / Curing :
- Silimor Resin Mortar is a Self-hardening due to its chemical reaction which occurs when the Powder & Resin are mixed together.
- An initial setting occurs in 6 to 8 hrs. at 30°C
- Final Setting occurs in 24 to 48 hrs. at 30°C
- Curing time: 7 days at °C
- Please ensure that no water shall be spilled over the bricks lining works before it completely cured.

Acid Curing:
When the bedding & jointing mortar is different, after the bedding mortar is properly set, cure the joints for a minimum period of 72 hours with 20 to 25% HCL acid before applying the resin type mortar. After acid curing, wash the free acid in the joints with clean water & allow sufficient time for thorough drying. Resin mortar shall then be filled into the joints.
