COMPATIBILITY :
"Shreecryl SS-545 is compatible with solvents like
ethyl acetate, isopropyl acetate, butyl acetate, toluene,
Xylene, to some extent with ketones like acetone, MEK, MIBK.
"SS-545 can be plasticised (low%) with DBP for the
manufacture of mosquito, cockroach masks. Oil / Solvent
soluble colours can be blended for coloured tapes / stickers.
Noncompatible with alcohols, water, pigments.
"SS-545 is compatible with Polyterpene or Hydrocarbon
tackifiers (Softening point 110 - 115ºC) at 1 - 2%
by weight dissolved in toluene (50:50 by weight)
APPLICATION TECHNIQUES
For continuous applications like roll / roll sticker manufacture,
Rigid PVC precoating for later application to plywood for
CTV cabinets, the Product is applied by roller. For small
jobs, the thinned resin can be applied by brush too. But
the brushes must be cleaned immediately after use.Spray
application is also adopted at lower consternation.
For
high peel applications like Rigid PVC/ GI sheets for housing
& Industrial applications.
IN
NO CASE SCREEN APPLICATION IS ADVISED. AS IT BLOCKS THE
SCREEN DUE TO VERY FAST DRYING.
USE
OF SHREECRYL SS-545
1)
For the manufacture of tapes like BOPP/PVC/PET/CELLOPHANE/PAPER/FOAM
where permanent tack and high peel strength are essential.
2) The latest fashion of manufacture of colour cabinet is
Rigid PVC precoated by silicone release paper; here the
PVC is coated on roller assembly with 30-35 gsm of resin
on dry basis.
3)
SS-545 is non-toxic after the film is dry. Hence it is being
used for making PVC based Band Aids. Similarly due to non-toxicity
and very negligible free monomer content. SS-545 is safe
for use in sanitary napkins/personal products.
4)
SS-545 when mixed with primary /secondary/cyclic amines
in the ratio 100pbw of SS-545, 0.005-0.05pbw of these amines
gives a thermo setting composition for permanent bonding
of plastic to plastic, plastic to any hard surface.
5)
Industrial applications where peel strength requirements
is 3-3.5kg/inch. Rigid PVC/GI or steel.
6)
Precoated foam (All Types) for insulation (Air conditing,
fridge, cars, SUV, Jeep -Top Insulation).
Advantages of SHREECRYL-SS-545
1.
Being manufactured under the personal supervision of highly
qualified and experienced persons, the product has excellent
consistency regarding viscosity, strength, clarity, molecular
weight distribution and flow properties.
2. Due to uniform copolymerisation, the shelf life is longer
compared to a product-polymerized hapzardly just to get
viscosity.
3.The product has better shelf life.
STORAGE OF SHREECRYL SS-545 (affected by high temperatures during storage)
As the product contains 50% or more Ethyl Acetate (Volatile Solvent with B.P. 77.1ºC),the following precautions during storage are very necessary :
1) Keep the drums / carboys in air circulating rooms / storage facility with good ventilation & not under sun.
2) Away from heat & fire.
3) Store below 30ºC. It is advisable to store 25ºC or below to enhance shelf life.
4) If unused for 10-15 days, open top lids & allow solvent vapour to escape. Add 2-3 kgs of Ethyl Acetate & roll the barrels and then store them.
5) At temperatures above 30-35ºC solvent evaporates & the product may thicken. To avoid gelling follow steps 1-4 above.
DO'S
& DO NOT'S
1.
Do not mix any other inferior product available in the market
under disguise of any acrylic copolymer in solution form.
As the copolymerisation reaction is very sensitive, narrow
range of molecular weight distribution is obtainable only
under stringent controls by highly skilled technologists.
2. Check the peel strength for every lot/batch before and
after exposure on high temperature (70 - 80ºC). Check
the supply for any micro-gells, which can cause non-uniform
application and later non-uniform tack.
3. When mixed with amines, the pot life of mixture is 8
- 12 hours only. So mix only requisite quantities.
4. Do not keep the drum/carboys filled with SS-545 open
near heat or flame. SS-545 is highly flammable due to ethyl
acetate.
5. As it is a solvent based system, shelf life is not warranted
above 6 months. Hence, no complaints what so ever will be
entertained after 6 months from the date of delivery.
