Methyl fibrino 500 carboxy polymethylene resin 20
Preparation and curing   The polyurethane tree solid particles were added to a mixed solvent of methyl cellosolve and tetrahydrofuran, and stirred slowly for several hours to dissolve them. Slowly add carboxypolymethylene resin while stirring to avoid caking and stir for 3h . Secondary coating, the coating solvent allowed to evaporate, at 60 ~ 80 ℃ activated a few minutes, bonding, may be cold bonding. Curing at room temperature.
use  The adhesive has high initial viscosity, plasticizer and grease resistance, and can be used for bonding of leather, polyvinyl chloride, rubber-plastic blend materials, and rubber, and has better performance than neoprene adhesive for shoes.
