Packaging and Storage


Packing	Storage
· 25Kg Paper bag · 600Kg Big Bag	· HS 770 storage should protect from moisture. · At storage temperatures above 30 or under pressure during storage may cause HS 770 caking occurs. · If HS 770 is not used up after ope ning, it should be sealed in time and used as soon as possible. · The optimal service life of HS 770 is 12 months, and the possibility of the product performances beyond the best use period will be reduced. · In order to ensure the best use effect of HS 770 , it is recommended to test the products performances before use.

Features & Benefits

· HS-770 as a VAE polymer powder can be redispersed well into polymer emulsion again after mixing with water.

· HS-770 with the characteristics of middle glass transition temperature, therefore, has a good balance between adhesion and flexibility, and wide universality of application.

· HS-770 can form film with suitable hardness inside and surface of the finished construction material product, which can significantly improve the cohesion, wear resistance, impact resistance and waterproofing ability.

· HS-770 with good acid and alkaline resistance, is good for the workability and weatherability of the construction material products which used it.

· HS-770 with good and wide compatibility, can use with almost all other chemical additives in diverse formulations.

· HS-770 not only retains the superior performances of the original VAE emulsion, such as good film formation, excellent adhesion and durable flexibility, but also improves the convenience and stability for transportation, storage and operation.

· HS-770is produced without adding plasticizer, film forming additives or solvent, so it has excellent environmental protection, low odor, low VOC.

Scope of Application

HS 770 is recommended to use in dry mixing mortar or powder construction material products, such as ceramic tile adhesive, tile grout, external wall insulation system (EIFS/ETICS), extrusion mortar for EPS component, waterproofing mortar, self leveling mortar, r epair mortar, decorative mortar, skim coat, fire resistant mortar, sound insulation mortar, Joint compound, AAC adhesive, gypsum products, etc.

Normally recommended dosage is 0.5~5% in total formulation.

· In EIFS/ETICS formulation, is recommended to add 2 ~4% dosage of HS 770 , which can

effectively improve the bonding strength, impact resistance and reduce water absorption.

· In skim coat formulation, is recommended to add 1~5% dosage of HS 770 , which can significantly reduce water absorption, improve the flexibility and bonding strength with the substrate.
