Tofogood-833 Super Matte Oil Resin Environmentally Friendly High-temperature Chemical Additive for Polyurethane Systems
Composition: 833 is a universal and environmentally friendly polyurethane ink connector modified with
polycarbonate, which has a special dendritic chemical structure.
Physical parameters:
Appearance:
Colorless to light yellow liquid
Nonvolatile content:
30-32%
Viscosity(mPa.s, 25℃):
800-1300
Solvent:
Ethyl acetate/Isopropanol
Function and Characteristics:
1. Widely applicable substrate, with good high temperature resistance, can be used for the preparation of thin film
varnish;
2. Excellent wetting and dispersing properties, no crystallinity, and good gloss of the prepared varnish,
3. The introduction of polycarbonate makes the product have excellent weather resistance, medium resistance,
and without yellowing;
4. It has good compatibility with various resins such as chloroacetic acid resin, NC, CAB cellulose, aldehyde
ketone resin, etc.
Application/Usage areas:
833 meets the legal and regulatory requirements for ink coatings used in food packaging, and can be completely
dissolved in mixed solvents of esters and alcohols. Therefore, it is suitable for preparing environmentally friendly
polyurethane light oil products without benzene and ketone. Due to its unique chemical structure, when used in
conjunction with curing agents, it can achieve excellent scratch resistance and temperature resistance. Therefore, it
is particularly suitable for preparing high-performance extinction oil and hand photosensitive oil.
Packaging: 190kg/drum
Features of 833 used in gravure matte ink:
① Print and replicate immediately, no sticking to guide rollers.
② High-temperature and scratch-resistant. Particularly suitable for eight-side sealing.
③ After curing, it has strong adhesion to over 70% of untreated BOPP films on the market.
④ Long shelf life after mixing with a curing agent.
Recommendations for using 833 resin in gravure matte inks
1 Adding 3-5% isopropyl alcohol to the matte ink formula can help open up the 833 resin, improve powder
wettability, and reduce viscosity.
2 The curing agent dosage should be 1-1.3% of the total matte ink volume (e.g., for 100 kg of matte ink, only 1-
1.3 kg of Covestro N75 curing agent stock solution is needed). Adding more than 1.3% is not recommended, as
this can cause the product to stick to the guide roller immediately after printing.
③ For customers with specific requirements for scratch resistance, if a 3-5% curing agent stock solution dosage is
required, we recommend adding a higher Tg resin and increasing the wax powder dosage to the formulation.
Otherwise, this can cause the product to stick to the guide roller immediately after printing.
