Fluorosilicone UV resin with clean odor, stain resistance and hand feeling-FSP8818

With the development of coating technology, the coating of many terminal applications must have a beautiful appearance, but also have excellent wear resistance, scratch resistance, fingerprint resistance, stain resistance, hand feel and other properties

For the anti-fouling system, Runao Chemical also launched two systems of anti-fouling resin, solvent-containing system and solvent-free system, both of which have received a good response from coatingol.

Runao Chemical Application Laboratory conducted a detailed test on the resin.

Anti-graffiti

The methods for characterizing the stain resistance of the coating film surface mainly include contact angle and oil resistance pen tests

In the oil-resistant pen test, the graffiti marks of the oil-based pen have obvious oil shrinkage, and the pen marks can be easily erased, and there are no traces left on the coating surface

We put the graffiti substrate into a 60°C oven, and after baking for 30 minutes, the pen marks can still be erased

Persistence

The durability of stain resistance is also an important performance index.

The FSP8818 branch chain contains a fluorine silicon structure.

Good toughness

Nowadays, the coatings on many 3C electronic consumer products have requirements for toughness, and basically have bending resistance tests.

And FSP8818 is a trifunctional resin, its main chain is polyurethane, and the side chain is modified by fluorosilicone, which has excellent toughness

At the same time, FSP8818 has high reactivity, and the measured energy of 300mJ/cm² can dry on the surface, which can meet the construction requirements of different applications

Water resistance

After the anti-fouling coating is tested in high temperature, high humidity or boiled in water, the surface of the coating is easy to be damaged, and the water contact angle is reduced, especially the system using fluorosilicone additives
.
FSP8818 has excellent hydrophobicity, and the fluorosilicon segment can also participate in cross-linking and is not easy to migrate
.
After boiling in boiling water for one hour, the paint film has no change, the adhesion has not decreased, the oil-based pen still has the phenomenon of shrinking when tested, and the pen marks can be erased
.

Leveling

FSP8818 has excellent wettability and can achieve a mirror leveling effect.
It can also achieve excellent leveling when it is coated on some low surface energy substrates
.
At the same time, the resin has good compatibility.
When matched with other resins, it will not cause shrinkage, pitting and other problems due to compatibility problems.
At the same time, the paint film can maintain high light transmittance, and there will be no appearance such as whitening and fogging.
Problem
.

Low odor

In some applications, the odor of raw materials has high requirements.
FSP8818 adopts a special synthesis process to strictly control the residue of small molecules and reduce the odor.
The resin itself has no special odor, and the paint film is completely odorless after curing, which satisfies the clean odor.
The requirements of different applications such as coatings and inks meet the requirements of environmental protection
