wet-mixed mortar admixture (JF-S1S2)
Category
Naphthalene series
Detail
Applications
1. JF-S1/JF-S2 is used for masonry, plastering, floor screeding mortar etc.
2. JF-S1/JF-S2 is made by many kinds of polymer material.
3. JF-S1/JF-S2 mixed with mortar can raise strength, durability, cracking resistance and binding power, and also can improve workability and moisture retention.
4. Using JF-S1/JF-S2 should be based on the situation with material test, strictly measure according to the mixing proportion in order to gain technical effect and economic benefit.
5. Mechanical raking time should be more than 3 minutes.
6. Mixing mortar with JF-S1/JF-S2 is prohibited for using directly on dry brick, dry wall and dry floor.
7. JF-S1/JF-S2 is valid for one year under normal conditions. If storage has surpassed the time, test must be done to confirm the validity.

Remark:
The tabular numerical value selected arenaceous modulus of fineness with 2.1—2.4 and put to use. JF-S1 and JF-S2 Should be increased appropriately, if arenaceous modulus of fineness more or less than this range.
The tabular content refers to the weight ratio of cementing agent amount of mortar.
Packaging, Transport and Storage
Powder is available in 25kg film-lined bags. Liquid is available in 100kg metal pail or iron tank. Other special package can also be available according to prior consultation.
It must be stored at the temperature above 0℃. Special measures should be taken to ensure entire package.
Dry and well ventilated warehouse is needed for storage. Quality guarantee of it is one year under normal conditions. If storage has surpassed the time, test must be done to confirm the validity.
