Epoxy-modified silicone resin IOTA E25

Description:

Epoxy modified polysiloxane resin IOTA E25 has excellent high and low temperature resistance, water and moisture resistance, good electrical insulation properties, and arc corona resistance.

Its weather resistance, chemical resistance stability, and corrosion resistance are also excellent. This product is widely used as a high temperature resistant anti-corrosion coating, which can be two-component curing at room temperature and can also be cured by baking at high temperature. It can be used as class H insulating paint.

Technical index:

Appearance: light yellow to colorless transparent liquid, no mechanical impurities

Solid content: 50±1%

Viscosity: 30~70 seconds (coating 4 cups)

Epoxy value: 0.03～0.06

Usage:

Two-component curing at room temperature, used with 650 polyamide or T-31. The added amount of 650 is 10% of the total resin; the added amount of T-31 is about 5% of the total resin. Add 5-10% KH550 of the total resin amount.

It can get better high temp. resistance after cured with silane coupling agent. Be careful not to make the solvent too weak. Butyl ester, PMA, butanol, etc. are recommended.

 Precautions:

 a. The dilution solvent used in this product must not contain water, sulfur-containing compound pyridine and its impurities, otherwise it will affect the adhesion, dryness and other properties of the resin paint film.

b. During the processing of this product, a large amount of flammable and explosive solvents will volatilize. Attention should be paid to strengthening the ventilation on site,

paying attention to fire prevention, and strictly cutting off the fire source. Operators should pay attention to labor protection.

c. The equipment and utensils used in the processing of this product must be clean. Strictly prevent the mixing of dust, foreign matter and water. d. Acids, alkalis, organic acid salts and amine compounds can accelerate the curing of this product and affect the heat resistance and electrical properties.

Therefore, this product should be strictly isolated from these substances during storage. Storage:

The storage period of this product is tentatively set for half a year.

This product should be stored in a ventilated, cool and dry place to prevent direct sunlight; prevent serious pollution by acid and lye, and should isolate the fire source and keep away from the heat source.

Package: This product is packed in 200kg drum.
