Performance evaluation
1.1 Foam break experiment
(1) Take 100ml 0.5% foaming solution into 1000ml measuring cylinder, then open air pump to bubble to 1000ml and turn off air pump.
(2) Take 100 ul defoamer into measuring cylinder and record time of foam elimination.
1.2 Antifoaming experiment
(1) Operate as foam break experiment.
(2) After foam disappearing, bubble once more, record the time the foam increases up to 1000ml.
(3) Operate (2) repeatedly and take the average time.

Foaming agent preparation
Take 1g foaming agent into 1000ml breaker, then add water to dilute and prepare foaming agent solution with 1% active content; Stir10 min and then add water to dilute as 0.5% solution for reservation.
Operation proposal
1. Add in each stage in production of water-based products.
2. Do not dilute defoamers to avoid influencing defoaming property.
3. If defoamer appears freezing or layering, it should be melted or mix even at first.
4. After adding defoamer, it should be stirred completely to make sure good dispersion of defoamer.
5. Suggested dosage is 0.2-1%.
6. Advise gradient test.
Storage
As liquid material, this product should be sealed and placed in a dry, cool, well-ventilated place at room temperature away from fire source. For any other information, please refer to MSDS.
