What is unsaturated polyester putty

    In recent years, due to the development of construction application technology, unsaturated polyester paint is applied to metal surfaces and used as an anticorrosive coating for the inner wall of metal storage tanks. Because it is non-polluting and non-toxic to food, it has been widely used in breweries.

Secondly, it is used as a surface for filling holes, filling seams, etc. on metal castings. When used, the polyester putty can be made by not adding the filler and the filler in the polyester resin.

Unsaturated polyester putty, also known as putty, gradually replaces traditional alkyd, perchloroethylene putty in car repair and machinery with its advantages of thick coating, fast drying, strong adhesion, easy grinding and no cracking. Industries such as manufacturing have been widely used and become one of the fastest growing embedded materials in the world in the past 20 years. In the past, ordinary waxy unsaturated polyester resins were used to make putty. This type of polyester putty is cured after being cured. In recent years, the trend has been to use air-drying unsaturated polyester resins to make putty, which has improved the sanding and adhesion of putty.

The requirements for unsaturated polyester putty are as follows: (1) low cost; (2) quick fingering after drying; (3) but not too fast drying to final hardness for polishing, and finally drying out, Putty should be strong; (4) excellent adhesion to the bottom material; (5) storage stability is better.

Simply put, it is the atomic ash, which gradually replaces the traditional alkyd and perchloroethylene putty in the industries of automobile repair and machinery manufacturing with its advantages of thick coating, quick drying, strong adhesion, easy grinding and no cracking. It has been widely used and has become one of the fastest growing embedded materials in the world in the past 20 years. Mainly used in automobile manufacturing, repair; furniture production; machine tool production; mechanical production; filled before painting.
