Product Details
DB-11M High temperature paint series
Ⅰ、Introduction
DB-11M is made of organosilicon resin, special heat-resistant and corrosion-resistant pigments, fillers, additives and other components. It has excellent heat resistance, rust prevention and corrosion resistance. It can withstand high temperature (200 ℃, 300 ℃, 600 ℃, 800 ℃) above 800 ℃. It is crosslinked and solidified at 180 ℃ - 220 ℃ / 30 minutes, which is convenient for construction.
Ⅱ、Scope of application
It is applicable to all kinds of high temperature resistant equipment, pipes, chimneys, exhaust pipes, high temperature hot gas furnaces, boilers, heating plates, etc., and all kinds of equipment with high temperature corrosion resistance required on metal surfaces.

Ⅳ、Construction reference
1.Before construction, the metal surface shall be degreased, derusted and treated with dirt to improve the adhesion of the film (it is better to conduct sand blasting treatment again);
2.Construction proportion [5kg paint: 1kg curing agent: 3kg diluent]
3.Xylene can be used as diluent, air spraying or brush coating is preferred, but it is not easy to dry;
4.If precipitate is found during storage, it should be stirred before use;
5.Due to poor steam oil resistance, attention shall be paid during construction.
Ⅴ、Transportation and storage
1. The product shall be waterproof and sunscreen during transportation to avoid collision, and shall comply with the relevant regulations of the transportation department;
2.The product shall be stored in a cool and ventilated place to prevent direct sunlight, isolate the fire source and keep away from the heat source;
Ⅵ、 Safety protection
The construction site shall be equipped with good ventilation equipment. Operators shall wear glasses, gloves and other protective equipment to avoid skin contact and inhalation of paint.
