Shellac resin

1,SOURSE shellac resin By the Lac is living in the host plants of the secretion of Lac insect, pure natural resin, the insulation with ABS, moisture, coating characteristics such as smooth and transparent, and non-toxic, tasteless, it is important that industrial raw materials. 2,Composition The main ingredients of Lac is resin.In addition, also contains waxy, pigment and other dissolving in water.Contents with host trees, The place of production, seasonal changes. 3,features 1 Unique thermal Sclerosing natural resins, at room temperature is easy to alcohol, with 125 ° c for three hours heating is not soluble in alcohol. 2 Soluble in water and acid, dissolved in alcohol and other organic solvents, be quick-drying arising out of the luster, decoration, durable films, on a variety of surface display height of adhesive, firm and full of elasticity.Therefore, waterproof, moisture, rust, decay, protective object. 3 Against ultraviolet light. 4 In alkaline solution can become a good film with high adhesion. 5 Can resist hydrocarbon solvents such as gasoline and so on, with oil-resistant. 6 Is a live in low-heat non-expansion, is a good insulator. 7 Take advantage of this unique technology company, select the production of raw material processing of Lac powder products already possesses comparable with Indian products.Products have a transparent, crocking, soluble in alcohol, coating drying fast and oil resistant strong acid and plasticity, fixing properties good. 4,Application 1 Heating with plasticity and castability, plus it has a large number of infiltration of absorption capacity, has fused cast industry. 2 Shellac resins with non-toxic.Excellent characteristics based on the above, shellac resins are applied at the alcohol coating, electrical insulating materials, printing ink, rubber padding and take advantage of its oil, acid is used for. 3 Other industries: in medicine, food, cosmetics, chemicals, metallurgy, mechanical, wood, paper, electronic and military and other fields were widely used. 5, product quality standards and specifications for Index nameProduction Code and quality standardCC0901 Category shellacCC0902 Of Lac des Grands Crus powderThe color index no. , ≤ 1822Hot alcohol insoluble,% ≤ 1.001.2Thermosetting time, ( Of 170 + 0.5 ° c),' ≥ 3.06.0Softening point, °C ≥ 7270Moisture,% ≤ 2.02.0, water-soluble contents of% ≤ 0.50.5Ash content,% ≤ 0.41.0waxiness,% ≤ 5.53-5acid value,KOHmg/g = 7365-80Rosin --Acetyl Iodide,Gl./100g = 2020grading ≥ -80Form FlakeA powderpacking Of 50 kg/ Paper drums orA/CARTONOf 50 kg/ Paper drums orA/CARTON
