Product Description
Alkyd paint is a type of coating whose main film-forming material is alkyd resin. Its core functions include anti-corrosion and fire resistance, but not all products possess both properties. Its basic characteristics include excellent weather resistance, hardness and adhesion. The main components are polyester resin and diluent, and it is widely used in industrial fields such as metals, steel structures, and ships.
Function Overview
Alkyd paint is a type of polyester-based coating. Its main components include polyester resin and alkyd ester thinner. It possesses both anti-corrosion and fireproof properties. It achieves rust prevention by forming a protective film on the metal surface, and after curing, it forms a hard film layer. It delays combustion by generating water, acid gas, carbon dioxide, and absorbing oxygen.
Fire Resistance Performance Analysis
- The basis for having fire resistance function
Chemical reaction mechanism: After curing, the film layer releases flame-retardant gases (such as carbon dioxide) during combustion and absorbs heat, thereby inhibiting the spread of flames.
Application scenarios: In some industrial and construction projects, alkyd paint is used to enhance fire resistance, such as steel structures, bridges, etc.
- The differences from professional fireproof paint
Alkyd resin is one type of fireproof coating. However, it should be noted that the fire resistance performance of ordinary alkyd paint is weaker than that of specialized fireproof paint.
Applicable scenarios
How to distinguish fire-resistant alkyd paint?
- Check the product label:
Alkyd paints clearly labeled as "fireproof paint" or "flame-retardant type" possess fire-resistant properties. Ordinary alkyd paints only emphasize anti-corrosion.
- Reference application scenarios:
Alkyd paints used on building walls and wooden components may focus on fire resistance, while those used on ships and machinery are more focused on anti-corrosion.
If you need to meet both anti-corrosion and basic fire protection requirements (such as rust prevention for ordinary steel structures), alkyd paint is an economical choice; if it is a high-risk fire protection area (such as shopping malls, tunnels), it is recommended to use professional fireproof coatings.
