Packaging and Storage


Property	Storage
ISO Tank	The suitable storage temperature for HS-450 is 5~37℃
Flexible Tank	If HS-450 is not used up after opening, the opening must be sealed as soon as possible to avoid emulsion crusting due to drying.
IBC tank	HS-450 has a shelf life of 6 months when unopened and stored under appropriate conditions.
220Kg Drum	After long-term storage of HS-450, recommend stirring it before use.
50Kg PE Drum	Since the pH of this product is acidic, it is not suitable to store HS-450 with iron container equipment directly. It is recommended to use stainless steel, ceramic, plastic and other material containers for storage.

Features & Benefits

· HS-450 with the characteristics of high solid content and low viscosity, it is very beneficial to the preparation of redispersible polymer powder, can reduce production energy consumption and improve product quality.

· HS-450 balances the bonding performance and flexibility very well, is applicable to be used for cement products, can remarkably enhance the bonding strength of mortars while also improve its flexibility.

· HS-450 is produced without adding plasticizer, film forming agent or solvent, so it has excellent

environmental protection, low odor and low VOC.

Scope of Application

HS-450 is recommended for making normal type VAE polymer powder, or use with cement and other fillers to get good balance performances products, or use as primer on substrates.
