Product description:

IOTA 18403 epoxy resin defoamer was 99.9% active special broken bubble poly organic siloxane, this product is a modified organic silicone compound developed according to the epoxy resin in the process of production and use of bubbles difficult to eliminate, has a good defoaming and anti-foaming property.

The typical property:

Appearance:  pale gray cloud of viscous liquid

viscosity CST,     3000-5000

effective content%   99.9

closed cup flash point ℃ > 100

Product features:                          

For oily resin system, has the greatly strengthened the defoaming and inhibit sexual.

rarely add quantity (1-200 PPM).

it is suitable for all solvent and non solvent resin system.

special effects with  the high solid content, high viscosity of epoxy resin, silk screen printing ink.

fast defoaming speed, long soaking time, less dosage of suppression.

low surface tension, to break the bubble dispersion in the system.

Have a wetting effect on base material, not easy the creation fisheye.

Product application:

epoxy resin, silk screen printing ink, UV ink is high viscosity of epoxy resin system (epoxy potting glue, epoxy products, epoxy floor paint, electric resistance welding ink) and high viscosity of silk screen printing ink typical defoaming agent;
Brush type, wood coatings, wood coatings, thick coating, polyurethane coating in the hand brush thick wood coatings, polyurethane paint system with little amount can achieve good defoaming effect, suggest to add 0.01 to 0.03% (the formula ratio).

General printing ink, plastic, paint, PU, light oil is suitable for all other oily paint/ink system defoaming, it can add can rarely achieve fast defoaming effect, only general 0.03% amount can be.

Usage:

If using the solvent to be diluted before use, dispersivity of the defoaming agent  will be improved, the defoaming efficiency will be improved, very convenient. In order to improve the dispersibility, generally choose aromatic and aliphatic department carbohydrates as dilution solvent, and antifoaming agent will be diluted to about 10% of the solution and then added.

Dosage:

organic silicon defoamer for foam fluid is very tiny amount, about 1-200 PPM, in order to determine the appropriate adding amount, please add 50 PPM (about 0.005%) of defoaming agent, observation of foam fluid bubble elimination performance, and then make a decision antifoaming agent is the most suitable addition amount.
