Product description:
IOTA 21403 type defoamer is an efficient siloxane modified defoaming agent developed according to the characteristics of siloxane combining with the high temperature properties of polyether.  It issuitable for oily resin system, and has a great strengthened the defoaming and inhibit function. Little amount (10-100 PPM), It applies to all solvent and non solvent resin system; The high solid content, high viscosity of epoxy resin, silk screen printing ink effects. Organic silicon strong defoaming agent system, the defoaming and inhibit sex is strong, and for a small influence on recoatability.
Typical physical properties:
Appearance:  pale yellow emulsion fluid

viscosity(25 ℃ / CST). 500-1500
Non-volatile portion of (%): 99.0 or higher
The refractive index of 25 ℃: 1.4110
Closed cup flash point ℃:  > 100
Product application:
Epoxy resin, silk screen printing ink, UV ink
Applicable to epoxy resin system with high viscosity and high viscosity screen printing ink and UV curing ink system.
Epoxy floor paint
Is epoxy self-leveling floor paint with standard organic silicon defoamer, add a little, strong defoaming and persistent foam suppression, and does not affect and burnish flowing property.
Wood coatings: brush heavy wood paint, polyurethane paint
In hand brush thick wood coatings, polyurethane paint system with little amount can achieve good defoaming effect, suggest adding 0.01 0.05% (total amount of formula).
General printing ink, plastic, paint, PU light oil
Applies defoaming of light oil, paint system, it can add can rarely achieve fast defoaming effect, only general 0.05% amount can be.
Application methods:
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.Generally choose aromatic and aliphatic as dilution solvent, and its dilution into add around 10% of the solution.
