7. Film forming mechanism
Alberdingk Boley
Film forming mechanism
Aqueous polymer dispersion (Solid Content: 30-60%)
Arrangement of particles, close contact
Deformation of the polymer particles
Surfaces of polymer particles are disappearing: polymer chains intermix
Polymer interdiffusion, leading to a mechanical stable polymer film
Stage I Evaporation of water
Stage II Particle deformation, T > MFFT
Stage III Coalescence
Stage IV Interdiffusion of polymer chains

31. Adhesion on difficult substrates
Alberdingk Boley
Adhesion on difficult substrates
Possibilities to work with adhesion promoters:
Use adhesion promoters as a separat primer
Add adhesion promoters directly to the primer as a paint component – more convenient-
e.g. in formulations based on AS we can add: 10-20% CPO 347W(Eastmann)

32. Targets for the future Low solvent containing and solvent free binders
Alberdingk Boley
Targets for the future
Low solvent containing and solvent free binders
Generally lowering of VOC
Chemical resistance improvement
Increasing of adhesion and scratch resistance
Easy to formulate binders
