They are therefore used in combination with other binder systems such as cellulose nitrate or chlorinated binders, for which they serve as plasticizers. With a sufficiently high dosage rate they can substitute the plasticizer normally required. Coatings based on acrylic resins adhere well even on difficult substrates and are resistant to aging. acrylic resins are not volatile, so the flexibility of films practically does not change with time.
EVP 002005 e, August 2005 Seite 4 von 5 acrylic resins and are hard to saponify and tenacious. The degree of polymerization of is lower than that of approx. 50 % in ethyl acetate. The lower of approx. 50 % in ethyl acetate allows the formulation of coatings with higher solids content or to incorporate binders of higher, e. g., cellulose nitrate 21 E instead of cellulose nitrate 24 E (DIN 53179). Coatings based on 700 L are well resistant to boiling water. LR 8820 a tacky and non-volatile acrylic resin with excellent fastness to light and resistance to saponification is preferably used to plasticize coatings raw materials and compounding plastics. Application acrylic resins are used, particularly in combination with cellulose nitrate, for formulating paper and film coatings, sealing wax, coatings for light metals and plastics and cellulose lacquers. Combined with chlorinated binders such as Laroflex MP grades, they yield coatings that are very resistant to hydrolysis for various substrates such as metals, concrete or fiber cement. When combined with suitable film-forming agents, they improve the adhesion of primers. Safety When handling these products, advice and information given in the safety data sheet must be complied with. Further, protective and workplace hygiene measures adequate for handling chemicals must be observed.
