1. Basic Information and Parameters

Our Factory Supply Gum Rosin with CAS number 8050 - 09 - 7 is a high - quality product. Gum rosin is a natural resin obtained from pine trees. It is a semi - transparent solid at room temperature, typically yellow to brown in color.

Key parameters of our gum rosin include:

• Acid Value: Generally, it has an acid value in the range of 165 - 175 mg KOH/g, which indicates its chemical reactivity and purity to some extent. A higher acid value often implies better quality in many applications.
• Softening Point: Usually around 70 - 85°C. This parameter is crucial as it determines the temperature at which the rosin starts to soften and flow, which is important for processing and using the product.
• Color: Our gum rosin has a relatively light color, which is preferred in many industries where color purity matters, such as in the production of some adhesives and coatings.

2. Product Uses

Factory Supply Gum Rosin has a wide range of applications across different industries:

• Adhesive Industry: It is a key raw material for formulating adhesives. Due to its good tackiness and bonding strength, it can be used in pressure - sensitive adhesives, hot - melt adhesives, and rubber - based adhesives. For example, in the production of packaging adhesives, gum rosin helps to ensure strong and long - lasting bonds between different packaging materials.
• Coating Industry: Gum rosin can be used in the production of coatings, such as alkyd resin coatings. It improves the hardness, gloss, and water - resistance of the coatings, making them more suitable for various surfaces, including wood, metal, and plastics.
• Printing Ink Industry: It is used as a binder in printing inks. Gum rosin provides good adhesion to the printing substrate, helps to control the drying speed of the ink, and gives the ink good gloss and color fastness.
• Rubber Industry: In the rubber industry, gum rosin acts as a tackifier. It enhances the tackiness of rubber compounds, which is essential for the processing and bonding of rubber parts during manufacturing.

3. Product Usage

When using our Factory Supply Gum Rosin, the following steps and precautions should be noted:

• Melting: Since gum rosin is a solid at room temperature, it needs to be melted before use. It should be heated gradually in a suitable container using a controlled heat source. The heating temperature should be carefully monitored to avoid over - heating, which may cause degradation of the rosin and affect its performance.
• Mixing: Once melted, it can be mixed with other ingredients according to the specific formulation requirements. For example, in adhesive production, it can be mixed with polymers, solvents, and additives. The mixing process should be carried out thoroughly to ensure uniform distribution of the rosin in the mixture.
• Application: After mixing, the mixture can be applied to the target surface using appropriate methods, such as brushing, spraying, or extrusion. The application process should be carried out under suitable environmental conditions, such as temperature and humidity, to ensure optimal performance of the final product.

4. Product Usage Case Studies

Case 1: Adhesive for Woodworking
A woodworking company was looking for a high - quality adhesive with good bonding strength and tackiness. They used our Factory Supply Gum Rosin in their adhesive formulation. By carefully adjusting the proportion of gum rosin in the adhesive, they were able to achieve excellent bonding results on different types of wood. The adhesive had good initial tack, which allowed for quick assembly of wood parts, and strong final bonding strength, ensuring the long - term stability of the wood products. The light color of the gum rosin also did not affect the appearance of the wood products, which was an added advantage.

Case 2: Printing Ink for Packaging
A printing ink manufacturer used our gum rosin in their packaging printing ink. The gum rosin improved the adhesion of the ink to the packaging materials, such as paper and cardboard. The
