Evonik Degalan P28 is a high-quality thermoplastic solid acrylic resin, designed for alkyd resin additives and printing inks. Polymerized with isobutyl methacrylate as the base monomer, it is in the form of a ground bulk polymer, which can naturally physically dry to form a film after solvent volatilization, fully soluble in various solvents such as alcohols and aromatic hydrocarbons, with good adhesion to metals, can promote the rapid drying of alkyd resins,
Natural physical drying: It can dry to form a film after solvent volatilization without baking, improving construction efficiency.
Excellent solubility: It is soluble in various solvents such as alcohols and aromatic hydrocarbons, facilitating formula preparation.
Significant drying acceleration effect: As an additive for alkyd resins, it can accelerate the drying speed of alkyd coatings and shorten the construction period.
Strong adhesion to metals: It has good adhesion to metal substrates, ensuring that the metal protective coating is not easy to fall off.
Alkyd resin additives: Promote the drying of alkyd coatings, improving coating drying efficiency and construction progress.
Printing inks: Used for various printing inks, enhancing ink adhesion and film formation stability.
Metal protective coatings: Used for the protection of metal substrates, providing good weather resistance and anti-corrosion performance.
Plastic coatings: Suitable for coating on plastic substrates, ensuring long-lasting and firm coatings.
Architectural protective coatings: Used for the protection of building surfaces, improving the weather resistance and decorative effect of coatings.
