Ⅱ)Molecular Structure
DMP60 resin is made from vinyl chloride and vinyl isobutyl eth-er through copolymerization, the resin possesses good adhesive property because of the vinyl isobutyl eth-er component. It possesses acid resistance, alkali resistance, salt resistance and chemical corrosion resistance because there are no saponifiable ester bonds in the molecular structure. The flexibility of coating film and the solubility of resin are very good because of the isobutyl eth-er in the structure. Meanwhile, there are no reactive double bonds in the structure, so the resin isn’t easily oxidized or degraded. The film of coating added DMP60 has atmospheric ageing resistance, good light fastness, and the film won’t easily occur yellowing and pulverization.
Ⅳ) Solubility
DMP series of vinyl chloride-eth-er resins are easily soluble in the following solvents, such as aromatic hydrocarbons, chlorohydrocarbons, esters, ketones, glycol eth-er acetate and some alcohol eth-ers etc. DMP resins have specially excellent solubility in aromatic hydrocarbons, they can dissolve in 20% toluene (xylene) solvent at normal temperature.
Ⅴ)Compatibility & Miscibility
DMP resins are miscible or partly miscible with the following copolymers, such as vinyl chloride copolymers, polyacrylates, unsaturated polyester resins, aldehyde resins, petroleum resins, natural resins, alkyd resins modified through oil and aliphatic acid, dry oil, tar oil and asphalt etc.
Ⅵ)Application
DMP60 can be applied in the base resin of coatings in the following fields, such as steel structure, containers, marines and those equipment working in the water, machinery and automobile engineering, transportation facilities, construction protection etc.With the rising codes of different DMP resins, their solid contents are accordingly decreasing.
Ⅶ)Packaging & Storage
1. Packed in multi-ply paper bag lined with plastic film, 20Kgs/bag
2. The package should avoid being crushed, and keep it away from the heat or wet environment.
