EPOTAL ECO 3702
EPOTAL ECO 3702
EPOTAL® ECO 3702 is a waterborne adhesive raw material that is compostable according to EN 13432. The adhesive is particularly suited for the production of multi-layer films based on a broad variety of compostable films and paper. The laminate has a high initial bond strength enabling direct further converting.
Applications for EPOTAL ECO 3702
It is recommended to apply EPOTAL ECO 3702 by gravure coating. For direct gravure coating, a smoothing bar helps to achieve a good coating quality. The smoothing bar should be operated against the web directions. A defoamer and a wetting agent are recommended when EPOTAL ECO 3702 is applied by gravure coating.
It is strongly advised to add a water-emulsifiable, polyfunctional isocyanate crosslinker to improve the overall performance of the adhesive.
If thickeners are added or if EPOTAL ECO 3702 is mixed with other products, it is important to make sure that none of the components has a pH of lower than 7 in order to prevent coagulation. It can only be mixed with anionic dispersions or with dispersions that contain a protective colloid.
EPOTAL CF 430
EPOTAL® CF 430 is a waterborne coater-ready flexible packaging compostable adhesive, which incorporates the base polymer EPOTAL ECO 3702. The adhesive is particularly suited for the production of multi-layer films based on a broad variety of compostable films and paper.
