RO-177 Coating Wetting Agent

RO-177 Coating Wetting Agent

Description:

Coating super wetting agent RO-177 is an incredibly potent and unique surface tension reducing agent for aqueous applications.It (@0.1wt%) gives an aqueous surface tension of 21.5mN/m. It provides superior sheeting,superwetting and penetrating properties to your formulations. It Prevents crater formation in aqueous coatings when the substrate has a low surface tension.

Coating super wetting agent RO-177 is a polyether-modified trisiloxane.

The chemical structure of silicone surfactant make it have super wetting property compared with regular adjuvant. It is a superspreading surfactant.

Applications:

●Water-borne coatings:

Substrate Wetting Additives.

Strong penetration power to millipore substrate

To enhance the leveling and flow.

Gloss enhancing.

Control foam and enhance air release.

● Solvent based coatings：

Substrate Wetting Additives.

To enhance the leveling and flow.

Control foam and enhance air release.

Gloss enhancing.

● Painting ink (water based ink,oil based ink):

Substrate Wetting Additives.

To enhance the leveling and flow.

Control foam and enhance air release.

Gloss enhancing.

Special recommend: It can be used as the wetting additives in the leather finishing agent or leather coatings,also can be used as the wetting of synthetic leather release paper.

Advantage：

No effect on overcoat ability, can be used in primer paint.  Anti-pipe.

In general,it is added in the process of paint mixing.

The recommended dosage:

0.5% (wt%) in solvent based system.

0.1-0.2% (wt%) in water based system.

You should determine the most proper concentration for your application through test.

Coating super wetting agent RO-177 is surely stable and it can keep surface activities for long time in PH=6-8 liquid. If the liquid mixtures is PH=3-6 or PH=8-10,you have to test to confirm the usage.
