Rosin X

Rosin is isolated from pine wood or pine stumps, Rosin is a frequent contact allergen which induces allergic contact dermatitis[1].

1. Flux: It has good effect on electronic circuit boards, has stable performance and good electrical performance. For example, hydrogenated rosin and polymerized rosin are film-forming resins that can be used to prepare fragrant solder paste. When the mass fraction of rosin in the flux is within In the range of 20% to 60%, increasing the rosin content can improve the spreading performance of the solder paste, improve the solder joint morphology, and significantly enhance the anti-collapse ability; when the total mass fraction of rosin in the flux is 40%, different rosin complexes The spreading test of the solder paste with the proportions all showed the characteristics of full solder joints, bright surface, and regular surroundings. The spreading rate was basically the same, about 82%. The anti-slump performance of the solder paste increased with the increase of the proportion of polymerized rosin. 2. Printed circuit board pre-coating agent: When rosin resin is used as a printed circuit board pre-coating agent, it has the characteristics of fast drying, good oxidation resistance and non-corrosion, and has good compatibility with alcohol-soluble rosin-based flux. 3. Water-soluble ink: a water-soluble fumaric acid-modified rosin resin that meets the requirements of domestic ink manufacturers. The water-soluble fumaric acid-modified rosin resin can be used as a binder for water-based inks or can be copolymerized with acrylic acid. Resin is compatible as a binder for use, and the price is low, adapting to the current development needs of the ink market, and has a good application prospect. 4. Tackifier: As a tackifying resin, rosin is widely used in the production of pressure-sensitive adhesives (SPA) due to its low price and excellent fast adhesion. The pressure-sensitive adhesive can be coated on the film substrate to make various Products such as instant stickers and self-adhesive tapes are widely used in production and people's daily lives.
