VI. Application Method:
Dissolution: Based on the required solution concentration and usage volume, slowly add an appropriate amount of colorless transparent dammar resin to a suitable organic solvent (e.g., toluene, ethyl acetate). Stirring is generally recommended to accelerate dissolution, but avoid excessive speed to minimize bubble formation. Moderate heating (40–60°C) may be applied during dissolution, ensuring temperatures do not cause resin decomposition or degradation. Once fully dissolved, the uniform transparent solution is ready for use.
Formulation: Depending on specific application requirements, pigments, fillers, and additives (such as plasticizers, drying agents, leveling agents, etc.) can be added to the dammar resin solution for formulation. Additions should follow a specific sequence, with thorough mixing to ensure proper dispersion of all components and meet diverse performance requirements.
Application: Multiple application methods can be used, including spraying, brushing, and rolling. Before application, ensure the substrate surface is clean, dry, and free of oil and impurities. During application, control the coating thickness, typically between 0.1–0.3 mm, based on product specifications and application techniques. After application, allow the solvent to evaporate naturally. Drying time varies depending on solvent type, ambient temperature, and humidity, typically ranging from 1–24 hours at room temperature.
VII. Storage and Transportation:
Storage Conditions: Store in a cool, dry, well-ventilated warehouse, avoiding direct sunlight and high temperatures. Maintain storage temperatures between 5–30°C to prevent resin softening or degradation from excessive heat, and avoid low temperatures that may cause resin brittleness. During storage, maintain sealed packaging to prevent resin absorption of atmospheric moisture or oxidation reactions with oxygen, which may compromise product quality.
Shelf Life: Under compliant storage conditions, the product generally has a shelf life of 24 months (refer to product label for specific details). Products exceeding the shelf life must undergo re-testing to confirm compliance with all performance indicators before use.
Transportation Requirements: During transit, prevent collisions, crushing, and severe vibrations to avoid packaging damage. Ship as general cargo, avoiding co-transportation with flammable, explosive, or corrosive hazardous chemicals. Maintain packaging integrity throughout transport to prevent moisture ingress, contamination, or reactions with other substances.
