Learning activities and teaching methods
Monologic (reading, lecture, briefing)
  • Contact teaching - 39 hours per semester
Learning outcomes
The subject links to the Technology of paint matters. Issues regarding surface pretreatment methods - physical or chemical - are discussed and organic surfaces application and preparation technologies are explained. Attention to design of coating compositions for various real environments is paid too. An excursion to external coatings manufacturing equipment is organized during semester. Student will be acquainted with techniques of material surface coatings, but especially with organic coatings application technologies.
Student will not only be able to design coating compositions, but also apply them on various materials using various technologies.
Prerequisites
Knowledge of organic chemistry and chemical engeneering.

Assessment methods and criteria
Oral examination, Home assignment evaluation

There is an oral examination. Primary form of exam is the debate about selected themes. Level of acquired knowledge, conceptions and application acquirements is examined. Knowledge is examined by test during semester and its result is included into total classification.
