Bayowet® FT 219 8
Polyether-modified, non-ionic fluorinated surfactant
Description
Additive to improve levelling and wetting properties of water- (Bayowet® FT 219 and FT 719) and solvent-based (Bayowet® FT 719) systems.
Solubility
aliphatic hydrocarbons insoluble
alcohols soluble
esters soluble
ketones soluble
glycol ethers soluble
glycol ether acetates soluble
water soluble
Properties
Bayowet® FT 219 and Bayowet® FT 719 both enrich on the interfaces and thereby decreasing the surface tension, after being solved in the different solvents. In this way even dirty or low energy surfaces can be wetted.
The use of Bayowet® FT 219 and Bayowet® FT 719 leads to:
- decrease of cratering and pin-hole tendency,
- decrease of orange peel,
- decrease of pigment float,
- increase of levelling during drying process,
- increase of pigment wetting and
- increase of adhesion on different substrates
Applications
The paint additives Bayowet® FT 219 and Bayowet® FT 719 show a good binder compatibility and high efficiency in a lot of binder systems.
Addition Rate
On principle it is possible to add the supplied form directly, but for better incorporation we recommend a predilution. Recommended addition rates are 0.03 to 0.1% active substance, relative to total volume.
The exact addition rate have to be found in pre-trials, because a overdose as well as a too low addition can cause unwanted side effects.
Re-coatability
An impairment of intercoat adhesion or re-coatability is not to be expected at low addition rates.
