WATER REPELLENT COATING

BIO DEGRADABLE ,

REPULPABLE AND RECYCLABLE

Product Details

This is a Innovative Water Borne Coating , based on Pre

Vulcanised Natural Rubber Latex / Synthetic Rubber

latex , and Naturally occurring waxes ,with high

performance, contains no plastic .

It provides superior Water repellency, with very good

barrier properties to moisture, oil , grease and fatty acids.

This coating is useful on both virgin and recycled paper /

fibre board. The coated paper is 100 % recyclable and

Bio degradable.

, Water Repellent coating ,is a eco-friendly alternative to

LDPE

Overview

This Water repellent coating ,is compounded using Pre

Vulcanized Natural Rubber latex / Synthetic Rubber

Latex ( SBR ) , Bee’s wax emulsion , and Soybean Wax

Emulsion . It offer’s good Water repellency replacing

the , usage of , plastics.

This is 100% eco friendly.

This is a Indian Patent Product

Application

Water Repellent Paper for the Manufacture of

1. Corrugated Boxes

2. Paper bags

3. Soap Wrappers

4. Paper Cores

5. Paper Drums

6. Paper Pallets

7. Pulp molded products

8. Other Packaging Applications.

More Application

Water Repellent Coating

Is useful as a Additive

for the Manufacture of

1. Molded Tray’s

2. Molded Pallets

3. Molded Boxes

for Industrial, food , Electronics and other packaging

applications.

Application Methods

Water Repellent , can be easily coated ,

1. By Gravure , Gravure &Myer bar , Kiss Coating

Method. Very low coat weights like 2-3 gm/

sq.mtr , provide excellent Water repellency

2. By Brush

3. By Spray Gun

Or

Can be Blended with The paper Pulp itself , to

manufacture Molded Pulp products for Packaging

Paper Recycling Process

The process of paper recycling involves mixing used

paper with water and chemicals to break it down. It is

then chopped up and heated, which breaks it down

further into strands of cellulose, a type of organic plant

material; this resulting mixture 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.

At this stage the Water Repellent Coating additive

can be blended. Then it can be made into new paper . The same fibres

can be recycled about seven times, but they get shorter

every time and eventually are strained out.

Paper Recycling Saves

1.Energy

It takes approximately 64% less energy to make paper

from recycled materials ( used paper )

than from virgin fibre ( trees0. 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 1005

recycled materials

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 save

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.

The mechanism of Water Repellency

Our 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 penetrate into the pores ,

and hence it is breathable.

Trapped Water vapour’s can easily slip through ,

however the water molecules are too large to

penetrate.

However our 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

Advantages

1. This is ideal Replacement for Plastic coated

paper

2. The Coated paper is Bio degradable ,

Recyclable

3. Excellent Coat ability on paper ,

4. Good Gloss

5. Very Good Water Resistance

6. High Coating speeds

7. Lower Coating weight ( approx. 4-5 gm dry per

sq. Mtr. )

8. Cost effective by at least 15-20%

Paper Water Repellency & Water Beading with our

additive

Our Water Repellent additive imparts greater water

repellency and water beading

We recommend a dosage of 5-7 % of Pulp for Consumer

grade and 7-12% for Premium grade

Our Water Repellent additive

provides greater water repellency.

it is available as an additive to recycled pulp or

virgin pulp.

it produces great results as a alone coating on

ready paper.

Technical Information

Our Water Repellent Additive is a low VOC,

hydrophobic , non silicone water borne emulsion

specifically designed to impart water repellency and

beading on paper. It is miscible with paper pulp or can be

applied on ready paper.

Our water repellent produces a clear finish.

it imparts pronounced and long lasting water beading.
