Description

Product information Coatingã��Ink and Painting Defoamer Silok®***2 Solvent-base silicone strong defoamer **0% activity special modified silicone Typical Physical Properties: The numerical data based on Silok internal testing purposes only Parameter Value Appearance light grey turbid viscous liquid Viscosity *5â��/cst *********0 Effective content % **0 Closed flash pointâ�� ï&frac*4;�**0 Refractive index *5â�� 1.***5 Product Features: ï�¬ Strong defoaming and foam suppression for oil base resin system. ï�¬ Add a little amount (****0ppm) ï�¬ Applicable to all solvent-based and solvent-free resin system for defoaming ï�¬ Special effects in the high solid content, high viscosity epoxy, silk screen printing ink. Product Application: 1. Epoxy resin, screen printing ink Silok®***2 is a normal defoamer for high-viscosity epoxy resin system (epoxy encapsulants, epoxy products, epoxy floor paint, ) and screen printing ink with high viscosity. 2. General ink, wood paint, plastic paint Silok®***2 is applied to all other paint / ink system for defoaming, only rarely amount can achieve rapid defoaming effect, only about 0.*3% dosage in general. Application Method: Dispersion of the defoamer will be improved if we utilize some solvent to dilute it before using, and its defoaming efficiency will be improved too, it become very convenient when use; usually choose the aromatic series and aliphatic series of carbohydrates as a dilution solvent, and diluted the defoamer solution to about *0% and then add it to enhance the dispersion. Dosage: It is a very little dosage for the foam fluid of organosilicon defoamers, about *****0ppm, in order to determine the appropriate dosage, please add the defoamer about *0ppm (0.**5%)and observe the elimination of the defoaming liquid foam, and then decide the most appropriate dosage of defoamer. Adding Methods as follow: â� ) Added in the foam solution in advance : With this method, the defoamer can suppress the bubble when it is added in advance. The defoamers can effectively eliminate the bubble in closed containers and devices. â�¡) Continuous trickle-down: When the foam solution is a case of cycling, flowing, the defoamer consumes away accompany by the foaming movement. In this case, using a method of continuous trickle-down the defoamer can effectively eliminate the bubbles. â�¢) Spray sprinkling: The use of spray spraying method is effective when a large number of bubbles produced in a short time, or want to eliminate temporary bubbles generated by the case. Using air guns target directly at the foam and spray the defoamer which has been diluted, as the effect of breaking foam arising from the foam of defoamer and the effect of foam suppression of the defoamer have been dispersed in the liquid, so it can eliminate a large number of bubbles in a short time. Diameter larger sprayer is ideal, if the sprayer aperture is too small, the defoamer come into being fog that can not be achieved effectively to eliminate the bubbles. â�£)Smear on the container: This method is quite effective that expect to control the bubbles has been generated in a certain circumstances. In the foam container intine paint the defoamer as shape of ribbon. The foam will be eliminated if the bubbles reach the surface of the defoamer. â�¤) Prepared the containers have been filled with defoamer in the foam tank: Prepare the containers have been filled with defoamer in the foam tank. The bubbles will be eliminated in the case of the bubbles rise up to the container and contact with the defoamer. However, this method is not for the device produces rapid bubbles, but this method is very effective to control a small amount of foam in a certain. case. Note: 1. Recommend to dilute the defoamer to about*0% of the solution by solvent before using. Add under the condition of a higher dispersion rate and ensure that the defoaming system can be dispersed evenly. 2. It may occur sediments in the defoamer during the storage, this will not affect the defoaming effect of the defoamer. Stir it until the defoamer become uniformly and then use. 3. Among the organosilicon defoamer, there are products restricted to the Labor Safety and Health Act, the Fire Services Act and other laws. Please pay particular attention to the following points: â� )Please do not let the defoamer adhere to the skin / mucus when using. On the case of the defoamer adhesion to the skin / mucus, please wash it immediately with soap, then rinse by adequate water. â�¡) Product contains solvent, please take notice of using it under the condition of ventilation, avoid smoking the solvent vapor.
