Epoxy Reactive Diluents are often used in epoxy resin coatings and are an important auxiliary material. It can reduce the viscosity of epoxy resin coatings, improve their fluidity, and can increase their curing speed and hardness. However, when using Epoxy Reactive Diluents, you also need to pay attention to some matters, otherwise it will affect the performance and service life of the coating. The following is a detailed introduction to the precautions for using Epoxy Reactive Diluents.
1. Choose the right diluent
When selecting Epoxy Reactive Diluents, it is necessary to consider whether its parameters such as volatility, polarity and reactivity are suitable for the desired coating. If an unsuitable thinner is selected, it may cause problems with the curing process of the coating and even affect its performance. Therefore, when using Epoxy Reactive Diluents, you must choose according to the specific situation. If you are not sure whether it is suitable, you can do a small sample test first.
2. The correct mixing ratio
When using Epoxy Reactive Diluents, it needs to be mixed according to the prescribed mixing ratio. If the mixing ratio is improper, it will lead to problems in the performance of the coating, such as poor leveling, insufficient hardness, etc. In order to avoid this situation, the mixing scheme can be formulated in advance, and the optimal ratio can be determined through testing and experimentation.
3. Pay attention to the volatility of Epoxy Reactive Diluents
Epoxy Reactive Diluents is a volatile organic compound, and its volatilization will lead to changes in the content of other components in epoxy resin coatings, thus affecting the performance of the coating. In order to avoid this situation, the volatilization of Epoxy Reactive Diluents should be reduced as much as possible, and low-volatility diluents should be selected, or anti-volatile agents should be added appropriately. At the same time, keep well ventilated during use so that the diluent can evaporate quickly and reduce the impact on other materials.
4. Store Epoxy Reactive Diluents
When not in use, Epoxy Reactive Diluents should be stored properly away from direct sunlight and high temperatures. Generally speaking, it is recommended to place the diluent in a dry, light-proof, airtight container, and try to avoid storing it in a humid place. In addition, storage containers need to be inspected before use to ensure their airtightness and cleanliness. If damage or impurities are found in the container, the container should be cleaned before use.
In short, the use of Epoxy Reactive Diluents in epoxy resin coatings is very common, but you need to pay attention to the above points when using them to ensure the quality and performance of the coating. Choosing the correct thinner, observing the mixing ratio, paying attention to volatility, storing thinner, etc. are all important measures to ensure the effect of paint.
