Temperature: Store VAE emulsion in a cool and stable temperature environment. Avoid exposure to extreme temperatures, both high and low, as this can affect the stability of the emulsion. Generally, a temperature range of 5°C to 30°C (41°F to 86°F) is recommended. 2.Avoid Freezing: Protect VAE emulsion from freezing temperatures. Freezing can lead to irreversible changes in the emulsion's structure, resulting in a loss of performance. If the emulsion has been exposed to freezing conditions, it is advisable to thoroughly mix and test it before use. 3.Containers: Store VAE emulsion in tightly sealed containers to prevent air exposure. This helps to avoid evaporation of water and maintains the stability of the emulsion. Ensure that containers are kept in an upright position to prevent leakage and contamination. 4.Ventilation: Store VAE emulsion in a well-ventilated area to prevent the buildup of heat and humidity. Adequate ventilation helps maintain the quality of the emulsion over time. 5.Protection from Sunlight: Shield VAE emulsion from direct sunlight or ultraviolet (UV) radiation. Prolonged exposure to sunlight can potentially degrade the polymer and impact the emulsion's performance. 6.Avoid Contamination: Prevent contamination by using clean equipment and tools when handling or transferring the emulsion. Contaminants can affect the properties of the emulsion. 7.Regular Inspection: Periodically inspect stored VAE emulsion for any signs of separation, coagulation, or other abnormalities. If any issues are identified, investigate the cause and take corrective action as needed. 8.First In, First Out (FIFO): Use a first-in, first-out system to ensure that older batches of VAE emulsion are used before newer ones. This helps prevent extended storage periods and maintains product freshness. 9.ElephChem's Recommendations: Always refer to the specific recommendations provided by the ElephChem for the storage and handling of the particular VAE copolymer emulsion you are using. Different formulations may have specific requirements.    

General properties The coating film of polyvinyl butyral (PVB) resin has good water resistance, alkali resistance and oil resistance (resistant to aliphatic, mineral, animal and vegetable oils, but not grate oil). Because PVB contains high hydroxyl. It is a base and has good dispersion of pigments, so it is widely used in printing inks and coatings. In addition, its chemical structure. It also contains hydrophobic acetal groups and acetate groups as well as hydrophilic hydroxyl groups, so PVB is compatible with glass, metal, plastic, leather and wood all have good adhesion.   Product name: Polyvinyl butyral resin CAS:63148-65-2 The appearance of polyvinyl butyral (PVB) resin is white spherical porosity particles or powder, and its specific gravity is 1:1; but the filling density is only 0.20~0.35g/ml. Applications PVB is widely used in adhesive safety glass interlayers, rust primers, baking paints, wood paints, printing inks, electronic ceramics and printed circuit board adhesives, metal-to-metal, metal-to-plastic adhesives, hot-melt adhesive modifiers, textile iron-dimensional waterproof processing, etc. New applications in various industries are constantly being developed. Storage PVB should be stored in a dry and cool place and avoid direct sunlight, and PVB should be stored to avoid heavy pressure. As long as PVB is not in direct contact with water, it can be stored for two years without affecting its quality.

General properties PVOH 725 is a polyvinyl alcohol with a hydrolysis rate of 72.5 mole %, specially developed as the main suspension agent for the polymerization of vinyl chloride suspensions. PVOH 725 has a lower molecular weight and lower viscosity. This results in a well-formed PVC that is uniform across the entire range of K values. Its high level of conjugated carbonyl groups in the polymer chain gives it superior grain size efficiency. Package Packages:In 25 kg/bag. Storage Modified PVA for PVC can be stored for an unlimited period of time under appropriate conditions that is in its original packs in closed, dry rooms, at room temperature.   As supplied, the product should remain fit for use for 12 months from the date of delivery. Beyond that date, the material may still be fit for use, but we would advise that material stored for 12 months or more after delivery should be tested before use.
