Show You How To Make Phenolic Resin Water Based Emulsion

Make a preparation of phenolic condensation compound, mix alkylphenol, sodium hydroxide and water together and melt it with heat, keep the it's temperature between 50-60°C for chemical reaction for 4 hours, and then cool it down to 40-50°C and add diluted hydrochloric acid to neutralize it.

Grind the Gum Rosin into powder, heat it up to be melted and then stir it, when the temperature up to 150-160°C, mix the melted rosin with maleic anhydride, and then heat it up to 190-200°C for chemical reaction for 1 hour.

Drop the phenolic condensation compound it to the melted gum rosin and heat them up to 230-240°C, add pentaerythritol and magnesium oxide into it for further reaction for 1 hour, and then raise it's temperature up to 270-280°C. Make it vacuumized when the acid number low down to 25mgKOH/g, keep the reaction going under the decompression until the acid number come to the desired value, the final process PhenolicResin Water Based Emulsion complete.

The Features Of Tackifier Resin

Tackifier Resin is made of rosin with a series of special modified process. It is soluble in aromatic, aliphatic, ester and ketone solvents. When being heated, it can be dissolved in EVA, SIS, SBS, NR, SR, SBR wax and other petroleum miscible polymer to get transparent solid. Such type of resin comes with light color, low odor, thermal stability, & excellent anti-oxidation, can improve adhesivity of hot melt adhesive, acrylic adhesive and other adhesives.

The Difference Between Gum Rosin And Ester Of Rosin

Gum rosin is made from natural rosin that collected from pine tree, and come through refining process, it can not only be direct used in various industries,  but also can be the basic material for other further processed pine rosin products.

Ester of rosin has gum rosin as basic material and processed with polyol ester, polyol ester usually include glycerol ester and pentaerythritol ester. Compare with gum rosin, ester of rosin has higher softening point (90-110°C) and acid number between 10-20, so it can has more application. Glycerol ester of rosin and pentaerythritol ester of rosin can be applied to coating and ink, but pentaerythritol has better fast-dry, hardness & glossiness, not only that, it has better water-resistance, alkali-resistance and faster solvent release. If you want to enhance the color stability and other performances of ester of rosin, you can use polymerized rosin or hydrogenated rosin to instead of gum rosin, the softening point of ester of polymerized rosin is higher than ester of rosin, but hydrogenated rosin is lower.

 

In addition to coating and ink, ester of rosin also can be used widely used in hot-melt adhesive, pressure-sensitive adhesive, rubber, tackifier and binder of road marking paint and so on.

Highlighted Features Of Tackifier Resin

As the key ingredient of adhesives and coatings, Tackifier Resin comes with lots of highlighted features, such as light color, low odor, thermal stability & excellent anti-oxidation, it can improve adhesivity of hot melt adhesive, acrylic adhesive and other adhesives. It can be dissolved in EVA, SIS, SBS, NR, SR, SBR wax and other petroleum miscible polymer to get transparent solid.

What’s Rosin Modified Maleic Resin?

Rosin Modified Maleic Resin also called Maleic Resin, it’s made of Gum Rosin and other chemical materials processed with unique formula and technique, the application of maleic resin is mainly on coatings and inks industries.

There a several types of maleic resins to meet different purposes. For carpentry paint oil varnish nd sealing paint, we can use #422 & #424, for C type gravure ink, we can use the resin with toluene. 103, 105, 107 & 115 are usually applied as adhesive material for ink & paper making industries.
