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
