What is Long Oil Alkyd Resin?
Long alkyd resin is the type of alkyd resin that contains the most oil among alkyd resins. The oil content in this type of resin is between 60 and 75 percent by weight. This high oil content gives Long alkyd resin unique properties. Short oil alkyd resin contains less than 30% fatty acid, medium oil alkyds contain between 45% and 55%, and long oil alkyds contain more than 55% fatty acid.
Special Features
Compatibility with some aliphatic solvents, very high pigment absorption, rapid drying, suitable chemical and mechanical resistance, resistance to yellowing are the features of this product.
Features and Usage
Very good scrubbing ability, excellent flow, very fast setting and complete drying. Very good weather resistance and filling power, good gloss and color retention. Universal binder for wood and metal surfaces.
Properties of long alkyd resin
Drying speed: This resin has a low drying speed and is therefore not suitable for applications requiring rapid drying. Chemical resistance: This type of resin has good chemical resistance to various chemicals such as acids and bases. High flexibility: Long alkyd resin has very high flexibility. Therefore, it is suitable for applications requiring a lot of flexibility such as matt and semi-gloss oil paints. Moisture resistance: This type of resin has very good resistance to moisture. Therefore, it is suitable for outdoor applications exposed to moisture.
Solubility: Long alkyd resin is soluble in aliphatic solvents.
Long alkyd resin applications
Oil paints:

Adhesives:
It is common for this resin to be used in the production of some adhesives.
Protective coatings:
This type of resin is used in the production of various protective coatings such as anti-rust coatings and waterproof coatings.
Mastics:
This type of resin is used in the production of various mastics such as insulation mastics.
Advantages of using long alkyd resin
- High flexibility
- Good resistance to moisture
- Good adhesion
- Reasonable price
In addition to the advantages mentioned, the low drying speed of Alkyd Long resin has limited its effectiveness in cases where drying speed is a priority. This resin has very little resistance to UV rays. Therefore, it is not a suitable option for outdoor applications (exposed to sunlight).
Safety tips
Long alkyd resin has high VOC that can be harmful to human health and the environment. Therefore, it is necessary to pay attention to the following points when using this material. When working with this resin, gloves, goggles and a suitable mask should be used. This helps protect your skin, eyes and respiratory tract. Work in a well-ventilated environment.

Uzun alkid reçinesi hangi tür uygulamalar için daha uygundur?
admin –
Uzun alkid reçinesi, yüksek yağ içeriği nedeniyle yüksek esneklik ve neme dayanıklılık gerektiren uygulamalar için uygundur. Bu özellikler, özellikle dış mekan uygulamaları, ahşap ve metal yüzeylerde kullanımı ideal kılar. Ayrıca, mat ve yarı parlak yağlı boyalar gibi esneklik gerektiren yüzeylerde de tercih edilir. Ancak, kuruma hızı düşük olduğundan hızlı kuruma gerektiren projelerde uygun değildir.
