It all started about two and half years ago.

The Govt. of India and Govt. of Maharashtra ,

imposed a Ban on Gutka packaging Pouches ,
made out of Plastics Film and aluminum foil.

The Govt. , notified that , the pouches as

mentioned above should be plastic polymer free.

22-08-2013 www.psadhesive.com 16
Promise to attend your Technical needs

I was applying my mind to develop a alternative

packaging material .
This prompted me to try paper with a suitable coating
on it which might be an alternative.

Suddenly , I realized that , I had a lot of information

stored in my PC , on water repellent / proof coatings.

22-08-2013 www.psadhesive.com 17
 I got in touch with some of these Manufacturers
based in USA , and Germany. There response was
Promise to attend your Technical needs

very quick to my sample requests and I eventually

received couple of samples from well renowned
companies like Michel man, Nu Coat , Aqua Base
Technologies and BASF

22-08-2013 www.psadhesive.com 18
 In order to carry out the coating trials , I then thought
of setting up a small Laboratory , in my home itself.
Promise to attend your Technical needs

The trials were very successful and , I could see a

great promise in the emerging Alternative
Technology .

22-08-2013 www.psadhesive.com 19
Promise to attend your Technical needs

This was the stage to consider the cost of the product.

I realized that the cost was very much on higher side ,
and although the product quality and performance was
good enough , the buyer would be really concerned
about the cost.

This prompted me to re think on the whole issue.

22-08-2013 www.psadhesive.com 20
 One day , I was on my morning walk as usual . It had
Promise to attend your Technical needs

just rained . While crossing through a lavish green

Garden , I could see Water droplets on some of the
leaves , shining like Pearl.
I suddenly realized , it was very much similar to the
water droplet formed on the coated paper in my Lab.

 That morning , was like a catalyst in my R&D

activity.

The nature , prompted me to think on

the alternative Natural Resources ,

available in abundance.

22-08-2013 www.psadhesive.com 23
 And
Promise to attend your Technical needs

The result of this was ,

That I could concentrate myself on the possible
usage of naturally occurring Waxes , such as
Bee’s Wax, Carnauba wax, soya wax etc.

The next challenge was , how to emulsify these

waxes in Water and how to bind them together .
Subsequently , I could develop methods to
emulsify them , in my Laboratory , and use of
Natural Rubber Latex , and or Styrene Butadiene
Latex , as a binder.
22-08-2013 www.psadhesive.com 24
 The results were very promising. I worked on

these formulations for nearly six months , and

then I could freeze the formulations.

The next stage was to protect my R&D work .

Hence , I approached a leading consultant for
Patent right Protection.

That is how , the Manufacturing / compounding

Process was Patented on 09/09/2011

22-08-2013 www.psadhesive.com 25
 Here , I must mention a fact .
Promise to attend your Technical needs

I consider myself just as a compounder.

The Doctor / or specialist Doctor is nobody else but
the great Nature . Nature has a solution for possibly
any task and the same are always available in
abundance. The job of a human being is just to
Identify the same and make use of it , in the most
practical manner.
This is what , I have done precisely.
The nature has graced us with lot many resources and
in return , we have to give it back.
I hope this is the real definition of Bio Degradability.

Coating Methods

22-08-2013 www.psadhesive.com 33
Pulp Blending
The process of paper recycling involves mixing Scrap paper with
water and chemicals to break it down. It is then chopped and
heated, to break it down into strands of cellulose, which is called
pulp, or slurry. It is strained through screens, which remove any
glue or plastic that may still be in the mixture then cleaned, de-
inked, bleached, and mixed with water.

22-08-2013 www.psadhesive.com 34
Pulp Blending

It is at this stage , mix

our Water Repellent
coating ,
approximately 5-10%
of the pulp quantity .

Then it can be made

into new paper.
This paper will exhibit
excellent Water
Repellent Properties.
22-08-2013 www.psadhesive.com 35
22-08-2013 www.psadhesive.com 36
 Recycling of paper
There are three categories of paper that can be
used as feed stocks for making recycled
paper.

Mill broke
Pre-consumer waste
and
Post-consumer waste

22-08-2013 www.psadhesive.com 37
Paper Recycling Saves
1. Energy

It takes approximately 64% less energy to make paper from

recycled materials ( used paper )
than from virgin fibre ( trees). Recycling one ton of paper saves
the equivalent of 70 gallons of gasoline or 3 barrels of oil.

2. Water

It takes 61 % less water to make paper from 100% recycled

materials

22-08-2013 www.psadhesive.com 38
Paper Recycling Saves
3. Land

Every ton of paper recycled saves 100 cubic feet of landfill space

4. Air

Making recycled paper results in 70% fewer air pollution than

making paper from virgin wood.

5. Natural Resources ( Trees )

for every ton of paper recycled , approximately 17 trees are saved

22-08-2013 www.psadhesive.com 39
Water Repellent
Chemistry
Water repellent or water proofing agents are generally of two
forms
Elastomeric coatings that adhere to the substrate and cure
to form a flexible and protective layer

Water repellent chemicals that penetrate deeply into the

substrate and they bond with it.

22-08-2013 www.psadhesive.com 40
The mechanism
of Water Repellency
The water Repellent coating
is formulated in such a way that the
surface tension of the same is
suitably adjusted
for easy wet out on the surface
( paper ) to be coated.
This is why the paper exhibits
superior water repellency.
at the same time it does not Repelle
penetrate into the pores , and nt
hence it is breathable. Permea
Trapped Water vapour’s can easily ble
slip through , however the water
molecules are too large to penetrate.
22-08-2013 www.psadhesive.com 41
 The mechanism of Water
Repellency

The water repellent additive

can be blended with the paper
pulp
and it wet out paper molecules
more effectively and bonds
them together
hence the moulded pulp is
100% water proof ,
with very negligible water
vapour transfer

22-08-2013 www.psadhesive.com 42
Advantages

1. This is ideal Replacement for Plastic coated paper

2. The Coated paper is Recyclable
3. Excellent Coat ability on paper ,
4. Good Gloss
5. Very Good Water Resistance
6. High Coating speeds
7. Lower Coating weight ( approx. 5-6 gm dry per sq. Mtr. )

FAQ
Shelf life of the product and life in the coating tray ?

It is a water Borne coating and Shelf life is not a issue at all. The
coatings needs to be circulated , if stored for some time in try ( Just
like Printing Inks, to avoid Skin formation ) . It is a , single
component system and cures on application of heat upto 70-75 deg
C. up the same from our Place.

22-08-2013 www.psadhesive.com 85
 FAQ
Dilution Procedure , to what extent and with what diluent
( water/ solvent ) ?

Diluent is Water. The ready to use coating is approx. 30 % solids

and you can dilute it up to 18-20 % solids

Curing Temperature , Tunnel temperature /subsequent

temperature ?

75-80 Deg C , can coat at around 40-50 mtrs/ min , for a Drying
tunnel length of 40 feet , equipped with a Hot air generator as heat
energy source of , 2 lakh Kilo cal Capacity.

22-08-2013 www.psadhesive.com 86
Curing time to achieve full water repellency ?

This is explained above.

How much time coating can with stand if water / Tea is poured
in a cup made with coated paper ?

This depends on the paper quality as well. But considering that

you are using Cup stock

Can this Coating Impart water repellency to metalized paper ?

We have to check the wettability on metallised side. This is new

requirement we have received. i will check it in my Laboratory
and inform You , as soon as possible.
