PROOF AGENTBRSS-718
1. Characteristics
Grease
proof agent BRSS-718 is a kind of cationic fluorinated acrylic copolymer
emulsion. It is based on “C6”, shorter molecule, and has better oil &
grease repellents. It can offer good oil and water proof performance for pulp
molding paper and paperboard products of food contact packaging.

3. Usage
The product BRSS-718 can be used in pulp/wet end, or surface
sizing process.
Pulp/wet end application: It can
be diluted in soft or deionized water at any rate. Generally, the addition
range of 0.5%-2.0% (relative to dry plup) can be used in combination with AKD and
other water-proof agent in order to give the product more waterproof. For
uniform dispersion, the process of dilution should be fully stirred.
Surface application:
Starch
and PVA can be applied evenly to the surface of paper or paperboard through
