Packaging and Storage


Packing	Storage
· 25Kg Paper bag · 600Kg Big Bag	· HS-788H storage should protect from moisture. · At storage temperatures above 30℃ or under pressure during storage may cause HS-788H caking occurs. · If HS-788H is not used up after opening, it should be sealed in time and used as soon as possible. · The optimal service life of HS-788H is 6 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-788H, it is recommended to test the product’s performances before use.

Features & Benefits

· HS-788H has undergone special hydrophobic modification, resulting in hardened mortars with strong hydrophobic properties. It is particularly suitable for applications where high hydrophobicity is required.

· HS-788H with the characteristics of high glass transition temperature and low film forming temperature, which fits for application scenarios that require high bonding strength and good adhesion.

· HS-788H with good acid and alkaline resistance, is good for the workability and weatherability of the construction material products which used it.

· HS-788H 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-788H is produced without adding plasticizer, film forming additives or solvent, so it has excellent environmental protection, low odor, low VOC.

Scope of Application

HS-788H is recommended to use in dry mixing mortar, such as waterproof mortars, decorative mortars,

repair mortars, skimcoat, etc.

· In waterproofing mortar, is recommended to add 3~10% dosage of HS-788H, which can effectively improve hydrophobicity and decrease water absorption.

· In skim coat formulation, is recommended to add 1.5~5% dosage of HS-788H, which can improve the flexibility, water absorption and bonding strength with the substrate.
