| Properties |
| KRISHNOL -NXZ is a defoamer for emulsion based on styrene-butadiene, acrylic, polyvinyl chloride, and its copolymers, ethylene vinyl acetate, vinylldene chloride and water soluble alkyds. |
|
| Dosage |
| In paint formulation 0.2 - 0.5 %, KRISHNOL -NXZ calculated on total formulation is recommended. For adhesives 0.5 -1 % KRISHNOL -NXZ based on the weight of the latex solid, is generally adequate. KRISHNOL -NXZ may be incorporated as supplied or dispersed in water prior to use. In paint manufacturing, it is usually advantageous to split the addition of the defoamer. Add half the normal amount to the pigment mix prior to grinding to suppress formation of foam. Add the remainder to the let down portion of the paint. |
|
| Miscellaneous |
| After prolonged storage, a slight sedimentation may occur. This does not change the characteristics of the product. It is recommended to homogenize KRISHNOL -NXZ prior to use. KRISHNOL -NXZ properties are not affected by freezing. If subjected to low temperatures, allow to warm to room temperature and mix well before using. |
