Introductions of sagging resistance chemical additive agent
Starch ether is mainly used in buildings, which can affect the consistency of mortar based on gypsum, cement and lime and change the flow resistance of mortar construction. Starch ethers are usually used in conjunction with modified cellulose ethers. It is suitable for both neutral and alkaline systems and is compatible with most additives in gypsum and cement products, such as surfactants, MC, starch, polyvinyl acetate and other water-soluble polymers.
When used in conjunction with HPMC, it can thicken, promote the internal structure, and has better crack resistance, hanging resistance, improvement and workability. The higher the proportion of methyl cellulose ether is, the greater the viscosity of composites such as mortar, binder, plastering and interfacial agent is. The addition of starch ether can obviously reduce the addition of cellulose ether. Very good rapid thickening ability, medium viscosity, weak water retention
Modified starch ether is a kind of chemical modified starch without plasticizer and organic solvent. Its appearance is white powder. Compared with other materials, it has good compatibility.
Modified starch ether is compatible with other buildings admixtures, especially suitable for construction dry mix such as mortar, adhesive, and plaster. Combined together with methyl cellulose in the building dry mix, they can realize higher thickening, stronger structure, sag resistance and workability. The viscosity of mortars, binders, and plasters containing higher methyl cellulose ethers can be reduced by the addition of starch ethers.
Features of sagging resistance chemical additive agent
1. Very good fast thickening ability, medium viscosity, certain water retention;
2. Small dosage, the extremely low addition amount can achieve high effect;
3. Improve the material's own ability to resist sag;
4. It has good lubricating property, can improve the workability of the material and make the operation smoother.
Shipping and packing method of sagging resistance chemical additive agent
Standard Packing: In 25kg bags out paper bags inner with LDPE bags
Store it in a cool, dry place below 30°C and protected against humidity and pressing, since the goods is thermoplastic, storage time should not exceed six months.
Attentions during applicate sagging resistance chemical additive agent
The above date is in accordance with our knowledge, but don’t absolve the clients carefully checking it all immediately on receipt. To avoid the different formulation and different raw materials, please do more testing before using it. We reserve the right to alter our product and without informing in advance.
