Silica Based Matt Hardener For Coating System

HT-802 Matt Hardener

HT-802 matt hardener, an additive that is based on silicon dioxide chemical properties, can enhance coating materials properties.

Below are the common applications of HT-802 matt hardener.

1) Epoxy resin coating: in this coating,silica matt hardener can be used as rheology control agents to improve coating's transparency

and it will also disperse evenly on the coating surface.

2) UV curing coating: HT-802 matt hardener is also suitable to use in UV curing coating and ink system when it is used as dispersant

to reduce coating's thixotropy.

STORAGE AND TRANSPORT

Stored in less than 30 °C, ventilated, dry, clean room, not near the fire source, heating, avoid direct sunlight, the product in 

the transport should be to prevent rain, sun, prolonged sun exposure. Storage products in line with the above conditions, since 

the date of production, effective storage period is 6 months. Over the storage period may be re-tested and the results were 

consistent with, can still be used.
 
HEALTH AND SAFETY

Coating powder is a non-toxic products, but should be avoided in the course of inhalation of dust. Proposed operators wear 

appropriate dust mask, glasses. If possible, try to avoid long-term skin contact with powder coating.
