Properties of polyurethane

coating

The properties of

polyurethane coating

vary from soft rubbery

Elastomers to hard

ceramic like systems.

The chemical bonds in

the systems are highly

cross-linked to each

other to create dense

system that consist

good chemical and

moisture resistance.

Elastomers are better

suited to protecting

substrates that tend to

move and flex like

concrete, but it also

works well on metallic

substrates.

Advantages

To the applicators, polyurethane coating provides an

assurance of achieving the desired result. Aside from

that, it has several advantages such as:

Good performance despite any weather

Performs good on heavy duty purpose

Low maintenance cost with long-term durability

Resistance to gouging and abrasion

Resistance to chemical attack

Flexibility and resilience

Require no post curing

Excellent in appearance

Non-flammable

has come a long way since World War II and

with the many advantages it provides, it is no

wonder it has become a majority choice in

surface protection. The coating itself is not only

durable, it helps to preserve the surface

underneath, allowing the item coated to last

longer
