Matters needing attention of Epoxy Vinyl Ester Resin
- The transportation shall comply with the regulations on the transportation and handling of hazardous chemicals in Chapter V of the State Council's "Regulations on the Safety Management of Chemical Hazardous Substances".
- The product should be stored in a cool place below 25ºC, avoid fire and isolate the heat source.
- The shelf life is 3 months under the specified storage conditions.
- Choose the appropriate epoxy resin material. There are various types of epoxy resin materials on the market, and it is important to choose the right type according to your needs. Generally speaking, there are different types of epoxy resins such as transparent, translucent, and colored, and each type has different properties and uses. When choosing, you should choose according to your own needs and construction objects.
- Preparation work and construction environment. Epoxy resin construction requires a dry and clean environment. Before construction, the construction area needs to be cleaned and ensured that there is no dust, oil and other impurities. For floors, they need to be sanded first to improve the adhesion of the epoxy resin. At the same time, keep the temperature and humidity of the epoxy resin within the appropriate range.
- Proportion and stirring. Epoxy resin is usually mixed in two parts. During construction, follow the instructions on the packaging, accurately mix the two parts of materials, and mix the two parts of materials thoroughly evenly. The mixing time should not be too long or too short to avoid affecting the performance of the epoxy resin. Generally speaking, the mixing time should be controlled at 3-5 minutes.
- Apply epoxy resin. Apply the mixed epoxy resin to the prepared surface using a scraper or roller. During the coating process, pay attention to the thickness of the coating. A coating that is too thick will cause the epoxy resin to flow unevenly, and a coating that is too thin will not achieve the desired effect. At the same time, pay attention to avoid the generation of bubbles. You can increase the stirring time or use special equipment to eliminate bubbles.
- Drying and curing. After applying the epoxy resin, you need to wait for a certain drying time to ensure that the epoxy resin can fully cure. The drying time is generally 24-48 hours, and the specific time can be adjusted according to the ambient temperature and humidity. During the drying process, care should be taken to avoid impact and excessive contact to avoid affecting the quality of the epoxy resin.
