Alkyd resin is a resin synthesized from alkyd and polyacid. Due to the side effects such as internal esterification and etherification that occur during the esterification reaction between multivalent alcohols and polyacids, a resin formation reaction with extremely complex structure occurs. The specific gravity of alkyd resin is 2.16-2.24, with a heat resistance temperature of 210. It is opaque and has excellent chemical corrosion resistance. Its main use is as a seasoning and adhesive for coatings.
As a modifier for polymers, tackifying resins are rarely used alone. In most cases, they are used as compounding agents to enhance the adhesion of polymers, improve initial tackiness, and reduce viscosity during operation or processing. Its application fields include hot melt adhesives, pressure-sensitive adhesives, coatings, inks, rubber complexes, and hydrocarbon modifiers, etc. It can be seen that most of the applications of tackifying resins are combined with rubber, so tackifying resins can also be discussed as tackifying agents for rubber. The only slight difference is that in the rubber products or tire industry, the usage of tackifying resins as compounding agents is much lower than that in industries such as adhesives.
Gum rosin or refined gum rosin is a kind of natural resin, mainly composed of various kinds of resin acids; it can be dissolved easily in many organic solvents and has special chemical activity. So, it is an important raw material for the production of paper, coatings, inks, rubber, soaps, electronic industrial products, food grade ester gum, rosin ester resins etc.
--Application--
1. Foodstuff Industry - Gum Rosin is firstly converted into hydrogenated rosin, and then used to produce chewing gum
2. Paints & Coating Industry - Rosin is a basic material for paint industry because rosin is easy to dissolve in alcohol,turpentine and others organic solvent. Rosin always is converted to resinate, and then refine with drying oil such as tung oil and mix with volatility solvent to produce various lacquers. Rosin also take important role in producing road coating, rosin firstly converted to rosin malefic ester or polymerized rosin or disproportionated rosin Polyols ester, and then used to make thermoplastic coating for road sign inunction.
3. Metal Processing Industry - Rosin mainly is used as solding aid and metal polishing agent. Rosin is a kind of weak acidity matter, it can remove oxidation film from metal surface and slightly erode the surface of metal, and therefore, lots of solding aid agents contain rosin.
4. Construction Materials Industry - Rosin mainly is used as concrete frothing agent and floor tiling adhesive.
5. Papermaking Industry - Most rosin was applied to papermaking industry as sizing agent. Rosin paper sizing agent can prevent printing oil soaking and dispersing from paper, improves the strength and smoothness of paper; enhances the anti-abrasion of paper. But crystal rosin is unfit for making paper sizing agent due to difficulty of saponification, subsequently makes spot on the paper; sometimes even makes the pipe jam in paper sizing agent producing.
