Coating Super Wetting Agent RH-209
1. Coating super wetting agent RH-209 is a polyether-modified trisiloxane.
Main content:
Polyalkyleneoxide modified Heptamethyltrisiloxane Cas no: 27306-78-1
2. Mechanism of Silicone Surfactant:
The chemical structure of silicone surfactant make it have super wetting property compared with regular adjuvant. It is a superspreading surfactant.
3. Product description:
Coating super wetting agent RH-209 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.
4. Key features and typical benefits:
Superspreader;
Penetrating
Sheeting
Emulsifier
Dispersant

● 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 RH-209 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.
