Little common sense about water-based resin!
Date:
2021-01-11
Water-based resin is a new type of resin system in which water replaces organic solvent as dispersion medium. It is fused with water to form a solution, and after the water is volatilized, a resin film material is formed. The water-based resin does not use the water-based resin itself, but requires a film material obtained after volatilization of water. Instead of solvent-based products in various fields of application. Waterborne polyurethane as the representative, can be widely used in coatings, adhesives, fabric coating and finishing agent, leather finishing agent, paper surface treatment agent and fiber surface treatment agent.

water-based resinPackaging: Water-based resin packaging is generally opaque plastic containers, while oily resin is generally used in metal packaging barrels, because water will corrode the metal, resulting in packaging leakage or product deterioration.
water-based resinStorage and transportation: sealed storage, and storage and transportation needs to ensure that the temperature is between 5-30 ℃, to prevent the temperature below zero, to prevent freezing, to break the stability of the resin in water. The storage temperature period can reach half a year and above.
water-based resinHardness: After the water in the water-based resin volatilizes, it will form a layer of film. What we need is this film, that is, the hardness of the film. When it comes to soft hardness, the demand for progress is a noun, glass transition temperature Tg, water-based resin belongs to high molecular polymer, and high polymer generally has three kinds of conditions. The temperature rise has a glass state with high hardness, a high elastic state with elasticity and a viscous flow state with fluidity, while Tg is the transition temperature between hard and elastic.
The viscosity of the water-based resin: the viscosity of the water-based resin testing instrument has a rotational viscometer (mPa.s), coated -4 cups (s), due to the different use of the scene with different viscosity, and the viscosity of the water-based resin can be adjusted by thickening agent.
