Oil glue is introduced to glue
Oil glue is filled with oil, dry glue is not filled with oil! In theory, all SBS can be used to make TPE, but it depends on the performance you want in the end! Glue is divided into: water glue and oil glue. The water content of water glue is large, and the price is relatively cheap. Oil glue is a semi-solid glue, of course, the price is much more expensive. Oil glue costs three times more than water glue. Oil-based coating adhesive is made by dissolving acrylic or polyurethane with oil-based solvent (toluene, DMF, butanone, etc.) as solvent. Its advantages are good film formation, good fastness, PU can stick hot air glue, is currently widely used coating glue. The disadvantage is due to the use of oily solvents, so the lack of environmental protection, especially now the price of oil, resulting in the price of oily solvents all the way up, most of the coating glue due to the cost is too high, so the use of relatively poor oily solvents, resulting in environmental protection is not up to standard, in addition with the further improvement of environmental protection standards in various countries, so the environmental protection requirements of coating glue are getting higher and higher.
Water-based glue introduction
Water-based glue is made by emulsifying acrylic or polyurethane resin through special emulsifying equipment with water as a solvent. Its biggest advantages are: variety, environmental protection, low price, now there are many coatings are water-soluble glue, such as: general water-soluble PA, water-soluble PU and skin film glue, oil wax, scraping paste and other functional paste. Water solubility, with its functionality, environmental protection, and low price, will be the direction of future coatings. Disadvantages are poor film formation, poor washing fastness, PU can not stick hot air glue. Oil-based glue is based on an oil-based solvent (toluene, DMF, butanone, etc.) as a solvent to dissolve acrylic or polyurethane. Its advantages are good film formation, good fastness, PU can stick hot air glue, is currently widely used coating glue. The disadvantage is due to the use of oily solvents, so the lack of environmental protection, especially now the price of oil, resulting in the price of oily solvents all the way up, most of the coating glue due to the cost is too high, so the use of relatively poor oily solvents, resulting in environmental protection is not up to standard, in addition with the further improvement of environmental protection standards in various countries, so the environmental protection requirements of coating glue are getting higher and higher.
