 Introduction :
|
|
Tuff Coats PU-101 Enamel is the two component system, designed to cross
link at room temperature. Base component is an acrylic polyurethane i.e.
Hydroxyl Functional Acrylic copolymer (pigmented) which reacts with
blocked polyisocynate adduct (Second component) to form tough film with
outstanding durability, chemical & weather resistance. The system
also gives excellent gloss and color retention properties.
|
|
The range of Application : |
|
An effective Top Coat for petrochemical refinery and fertilizer industries. The
system is useful for maintenance coating, structural coating as well as
for floor coating. Because of rapid curing at room temperature and
excellent toughness and abrasion resistance, resistance to heat, oil, Alcohols
Acid & salty weather, the system gives wide range of application in
Aircraft finishes, transport finishes and chemical industries.

Application :
|
|
Before application of Top-coat PU-101 Enamel do
all necessary pretreatment of the job. For M.S.surface remove grease oil
& other contamination by using proper de-rusting & Phosphating
chemicals to clean surface.
Apply properly TUFF COAT PU-102 primer coat or
Hi-Build wash primer. After proper drying of primer coat apply PU-101
Enamel.
For old concrete remove salt deposition /
fungal growth , loosely bound coatings, dust particles and make the
surface rough. Also for new concrete do the needful pretreatment /
priming and then apply Top-Coat PU-101 Enamel.
Stir the base component thoroughly & mix
four parts of base & one part of hardener by volume to uniform
consistency. Keep it for 15-30 min for stabilization & stir again
before use. Make required viscosity as per application method with TC /
PU 101 Thinner. Mix the above material as per requirement because of 4-5
hrs.
Pot life ; close the containers
immediately to avoid the chances of the moisture absorption in material.
Do not apply in humid condition during the raining, fog or mist or at
very low temperature i.e. bellow 7o c

STABILITY OF HARDENER
-
|
|
Once the hardener container is opened ; try to consume it
immediately because it
reacts with Hydroxyl groups present in atmosphere & it results in to
gellation.
