Silver Silicone High-temperature Coating (air-drying) 14-1

Browse Similar Models by CategoryThis model belongs to: Heat-resistant, Silicone

Composition

Composed of modified silicone resin, aluminum powder, heat-resistant extender pigments, additives, organic solvents and other components

Dry-type silicone heat-resistant coating.

Key characteristics

Good heat resistance, usable in the range 300–500 °C

Features self-drying at ambient temperature, but the film properties are better after baking

Good properties including strong adhesion, moisture resistance, impact resistance and atmospheric corrosion resistance

Use

Suitable for boilers, blast furnaces, ovens, exhaust pipes, external walls of high-temperature pipelines, metallurgy, chemical industry, power plants,

Used for high-temperature protection of steel surfaces of large high-temperature equipment that cannot be baked, such as in the glass manufacturing industry.

Application parameters

Drying Time (200±2°C) ≤ 3 h

Note: Hard dry here refers to the method specified in GB/T1728 "Determination of Drying Time of Paint and Putty Films"

has reached the requirement of hard dry by the standard method, and the coated item can be handled and installed, but its paint film

Not crosslinked or cured; the film must achieve true cure through the elevated temperature of the coated object during service.

At the same time, it must be noted that when the coated item is used for the first time, the temperature must be raised gradually and held, until the work

operating temperature, so that residual solvents and low-molecular-weight compounds from crosslinking escape slowly, to avoid

Prevent blistering and detachment of the paint film caused by sudden high temperatures forcing solvents and the like to rapidly break through the film.

Recommended number of coats

1–2 coats, DFT 20–40 µm, as required. One coat (20 µm) heat resistance

Good adhesion; applying two coats (40 µm) can improve anti-corrosion performance. The film of heat-resistant paint should not be too thick,

Otherwise, blistering and peeling are likely to occur at high temperatures.

Preceding coat

May be applied directly over steel prepared to Sa 2.5

E06-1 Inorganic Zinc Silicate Anticorrosive may also be used as the primer to improve anticorrosive performance. Generally

E06-1 Inorganic Zinc Silicate Anti-corrosive Primer one coat (40 µm), 14-1 Silicone Heat-resistant Topcoat 1–2 coats (20–40 µm) is recommended

Surface Preparation

• Mill-scaled steel: abrasive blast clean to Sa 2.5

Mill-scale-free steel: grind with abrasive discs to St 3

Steel with existing coating: abrasive blast clean to Sa 2.5; or remove all old coating and grind with abrasive discs to St 3

For best results, after applying the first high-temperature coat, heat to the service temperature, and apply the second coat after cooling

Application conditions

The substrate temperature must be at least 3 °C above the dew point, but not more than 60 °C

• Relative humidity not more than 85%

Application method

Note

Control of thinner quantity and thorough mixing during application are important. If viscosity is too high, after coating the film

poor leveling, prone to orange peel or brush marks; relatively low viscosity, prone to sagging, loss of gloss, and hiding

disadvantages such as poor leveling. Typically, the viscosity is adjusted to (flow cup No. 4, 25 °C) 15–25 s during spraying, and for brushing

Adjust viscosity to (Ford Cup No. 4, 25 °C) 25–35 s.
