characteristic:
Like all vinyl-chloride vinyl-acetate copolymer, BLM has strong resistance to abrasion, strong water resistance, not affected by acid, base, salt, oil and etc under room temperature, chemically stable.
Ketone and ester are common solvents for BLM, chlorhydrocarbons are rarely used. Ketone is the best solvent for BL-25, ester can only dissolve part of BL-25.
Chlorhydrocarbon such as Methylene dichloride and 1,2 dichloroethane can completely dissolve BLM, while trichloroethane and tetrachloroethane will only cause BLM to expand. Alcohol and fat cannot dissolve or expand BLM. Some Benzene solvents can partly dissolve or expand BLM.
BLM is a great adhesive for metal, especially aluminum, and also for PVC products, paper, fiber, glass, china, rock, and wood.
Typical uses:
1. Adhesive for medical packaging aluminum foil 2. Metal coating
3. Coating for electronics and toys 4. Anti-corrosion coating, especially for ships We will provide detailed specifications upon request.
Mixture:
BLM mix well with PVC resins, epoxide resins, alkyd resins, phenolic resins,acrylic resins, polyester resins, and etc. It is also not affected by acid, base,salt, oil and etc. under room temperature.
BLM does not mix well with nitrocellulose, polyvinylacetate and polyvinyl butyral
Color and filling:
Please note that while BLM will mix well with most standard coloring solutions,those solutions containing Zinc, Cadmium, and oxidized iron will cause BLM to decompose under high temperature. BLM by itself is heat resistant and anti-UV, but under special circumstances, it is best to improve the stability of the BLM during processing. Epoxy stabilizers are best heat stabilizers for BLM. If higher heat stability is needed, we suggest the use of organo-tin stabilizers together with epoxy stabilizers; organo-tin stabilizers synergize with epoxy stabilizers to provide better stability. Also, it is best to add anti-UV stabilizers.
Processing:
To avoid discoloring, both the solution and the final product should avoid iron during processing and storage. The solution should be stored in covered instruments.
Storage:
If stored in dry places under 25°C, the product can be stored for up to 12 month.
If the product is stored for longer than it’s recommended storage life, the product may still be usable, but the customer should use with care according to the conditions of the product and the requirements of the final product.
Packaging:
Each PP bag is 25kg with inside plastic poly bags.
