Working and Safety Equipment



- Aromatic systems (Desmodur / Desmophen):- NCO/OH (2 pack PU, aromatic)- NCO/H2O (1 pack PU, moisture curing)- NCO/Amine (2 pack PU, amine-aromatic)- NCO/Polyolemulsion (3 pack PU, Desmolith)

- Desmocap

- 2 pack PU, water borne (Bayhydrol / Bayhydur )

- Aliphatic systems (Desmodur / Desmophen):- NCO/OH (2 pack PU, aliphatic)- NCO/H2O (1 pack PU, moisture curing)- NCO/latent Hardener (1 pack PU, moisture curing) - NCO/Amine (2 pack PU, Aspartates)

- Products: - Desmodur VL / VL 50 / VL R20 - Desmophen 1150 / 1145 / VP LS 2284 / 550 U etc.

- Application: - industrial flooring- Advantage: - solvent free, self levelling coatings

- higher reactivity than EP at lower temperatures - soft to hard - adjustable properties- Disadvantage: - sensitive regarding application conditions

- hydrophilic / hydrophobic properties of polyols

TECHNOLOGY OPTIONS -TECHNOLOGY OPTIONS -2 pack PU 2 pack PU with aromatic isocyanateswith aromatic isocyanates


TECHNOLOGY OPTIONS -TECHNOLOGY OPTIONS -1 pack PU, 1 pack PU, moisture curing moisture curing -- with aromatic isocyanates with aromatic isocyanates

- Products: - Desmodur E 21 / E 23 / E 29- Application: - industrial flooring and parking decks

as primer/sealer on concrete- Advantage: - less sensitive regarding application conditions

- easy handling at the construction site - higher reactivity than EP at lower temperatures

- Disadvantage: - low tolerance regarding film thickness - high viscosity of Desmodur E 21 / E 23 - formulations mostly solvent containing


TECHNOLOGY OPTIONS -TECHNOLOGY OPTIONS -2 pack PU, 2 pack PU, with aromaticwith aromatic//aliphatic isocyanatesaliphatic isocyanates and and aromatic aminesaromatic amines

- Products: - Desmodur E 15 / VP LS 2371- Application: - parking decks, balconies etc.

waterproofing membranes in general- Advantage: - not sensitive regarding application conditions

- highly flexible but relative hard coating material also at low temperatures, used for water-proofing

- Disadvantage: - higher raw material price - relatively high viscosity - use of aromatic (non carcinogenic) amines as hardener


TECHNOLOGY OPTIONS -TECHNOLOGY OPTIONS -DesmocapDesmocap

- Products: - Desmocap 11 / 1180 / 12- Application: - parking decks, balconies etc.

- Epoxyd- Elastification- Advantage: - less sensitive regarding application conditions

- flexible to hard coatings depending EP/Desmocap ratio broad glass transition temperature range, used for crack bridging systems

- Disadvantage: - high viscosity (~ 100.000 mPas for D‘cap 11)

Recommended ProductionRecommended Production Equipment Equipment


- higher productivity:- higher productivity:

- lower raw material prices- lower prices of formulations (more filler, lower viscosity)- easier to apply- shorter through curing times / longer pot life

- increased environmental protection and health care:- increased environmental protection and health care:

- solvent free systems- no aromatic (non - carcinogenic) amines
