METOLAT 288

MET METOLAT 288

METOLAT 288 is a surface active product formulated for low viscous, finely dispersed pigmented coatings. Upon addition of this special defoamer the surface tension of the medium is changed. Existing foam will be destroyed. Recreation of foam will be avoided. OLAT 288 is a surface active product formulated for low viscous, finely dispersed pigmented coatings.

性能/应用

?     METOLAT 288 is a highly effective defoamer, which is preferably used for preparations of coating colours.

?     For most coatings 0,01 to 0,2 % METOLAT 288 is required, calculated on the dry weight of the coating.

?     A dosage quantity of 1 % should not be exceeded.

?     A homogeneous distribution of the defoamer in the system is important to ensure optimal use of the outstanding effectiveness of METOLAT 288.

?     Therefore METOLAT 288 should be added in steps with sufficient turbulence in foaming system.

?     Because of its anionic characteristic METOLAT 288 has to be checked concerning its compatibility with the used binder.

?     The product will easily emulsify in water.

?     That is why post-addition will be possible to the coating colour loop.

?     The anionic nature of the product requires the product to be added to water, when used in the manufacture of emulsions.

?     METOLAT 288 should be used where good levelling is needed.
