ABOUT:

Blocked aliphatic polyisocyanate based on HDI.In combination with polyol components for the formulation of lightfast one-component polyurethane stoving coatings.

Product Types:

  • HDI

  • PIC

  • Aliphatic polyisocyanate

  • Crosslinkers

  • Polyisocyanate

  • Hardeners

  • Polyisocyanurate

  • Isocyanate

  • Reactive system

Material:

Coatings, paints & inks

Weather resistant, Solventborne, Flexible, Thermally resistant, Elastic

General Characterization:

Desmodur PL 350 MPA/SN is a blocked aliphatic polyisocyanate based on HDI.

It is suitable for use in combination with polyol components for the formulation of lightfast one-component polyurethane stoving coatings.

 

Storage Conditions:

Desmodur PL 350 MPA/SN should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. Storage at higher temperatures will result in increase of color and viscosity. Storage at significant lower temperatures will result in solidification. This solidification is reversible by briefly heating the product without adversely affecting the quality of the product. Recommended storage temperature is 0º-30ºC.

These values provide general information and are not part of the product specifications.

Stability / thinnability:

DURANATETM 22A-75PX can be thinned with esters, ketones and aromatic.hydrocarbons such as ethyl acetate, butyl acetate, methoxypropylacetate (PMA),methyl ethyl ketone, methyl-butyl ketone, cyclohexanone, toluene, xylene, Solvesso#100 and mixture thereof. Generally speaking, it has good compatibility with thesolvents mentioned. However, the solutions formed must be tested for their storagestability.

Only PU grade solvents can be used (max. 0.05% water, absence of reactive groupssuch as hydroxyl or amines groups). Aliphatic hydrocarbons such as hexane,cyclohexane, methylcyclohexanes and mineral spirits, are unsuitable as solventsbecause of their poor solubility.

DURANATETM 22A-75PX should not be thinned to below a solid content of 40%.Prolonged storage of solution with lower solid content may result in turbidity andsedimentation.

Compatibility:

 

 

Mixing ratio of DURANATETM 22A-75PX with polyols is based on NCO/OH equivalentratio of 1/1 .

Storage:

DURANATETM 22A-75PX is sensitive to moisture and should therefore always bestored in sealed containers.
