Tetrahydrofuran 500
Methyl cellosolve 500
Carboxy polymethylene resin 20
Preparation and curing polyurethane solid particles were added to the tree methyl cellosolve and mixed solvent tetrahydrofuran, slow stirring for several hours, to dissolve. Carboxy polymethylene resin, slowly add in stirring and avoid caking, stirring 3h. Glue 2 times, Tu after solvent evaporation, were stuck between 60 ~ 80 ℃ activation for several minutes,, can also be cold bonding. Room temperature curing.
Use this glue stickiness high resistance, plasticizer and grease, can be used for bonding leather, PVC, blending with plastics, rubber, chloroprene adhesive performance than good.
