Production Description
The coating system consists of amine-terminated polyether resin, amine chain extender and MDI prepolymer, functional filler is added, and the product belongs to spraying, self-cured and thick coated polyurea. It is used together with ground coat paint and facing coating to form a firm, tough and decorative ground protection system.
Recommended Applications
Applied toanti-corrosion Pipeline,Tank,Saline tanks,Oil tanks,Platforms,Sewerage pools

Notes:
1.Polyurea product is intended for industrial use by properly trained professional applicators only.
2.Thoroughly mix container of B component with an air-driven power mixer for a minimum of 15 minutes prior to application.
3.Adding a nitrogen blanket is strongly recommended for use on the “A” component for storage after opening.
4.It is a100% solid production is strictly prohibit add any diluents.
5.The quality and fitness of the product is depending upon the proper mixture and application of the component by the applicator.
6.This specification is an accumulation of long term testing and experience. Published technical data and instructions are subject to change without notice.
Packaging:
Part A: 220kilogram per drums.
Part B: 210 kilogram per drums. (Custom package available at additional charge)
One set:430 kilogram totally
Storage:
(1).The A component is affected by moisture and must be protected from moisture contamination. Containers are factory sealed with an inert gas to prevent contamination. Keep all containers tightly closed during storage. For further storage after opening, containers must be purged with nitrogen gas or dry air and tightly sealed to protect from moisture contamination.
(2).Store drums and pails in a cold, dry and ventilated location between 15 ℃ and 40 ℃.
(3).Twelve months in sealed unopened containers.
(4).Keep away from fire and heat source.
(5).Keep away from rain and sun.
Shipping:
10 days upon receipt of payment by shipment on Shanghai/ Qingdao Port.
