Solubility / thinability

Starlite 5000 BA/SN can be thinned with esters,

ketones and aromatic hydrocarbons such as ethyl acetate,

butyl acetate, methoxypropylacetate, acetone, methyl ethyl ketone,

methyl isobutyl ketone, cyclohexanone, toluene,

 

Xylene, solvent naphtha 100 and mixtures thereof.

 

Generally speaking , it has good compatibility with the solvents listed. However, the solutions formed must be tested for their storage stability. Only PU grade solvents should be used (max. 0.05% water, absence of reactive groups such as hydroxyl or amino groups). Aliphatic hydrocarbons are unsuitable as solvents.

 

Starlite 3390 BA/SN should not be thinned to below a solids content of 40 %. Prolonged storage of a solution with a lower binder content may result in turbidity and sedimentation.

Compatibility

Generally speaking, Starlite 3390 BA/SN can be mixed with the following products: aliphatic polyisocyanates such as Starlite 100, 75, 3200, 3400, 3600 and Starlite® 4470; aromatic polyisocyanates such as Starlite HL and IL; polyester polyols such as Company 670; polyacrylates such as the Company A products. However, the compatibility of the combinations used should always be tested. Starlite 3390 BA/SN is not compatible with branched polyester polyols such as Company651 or polyether polyols such as Company BT.

   
Properties / Applications

Starlite 3390 BA/SN is used primarily as the hardner component for lightfast two-component polyurethane coatings with high resistance to chemicals and weathering, very good gloss retention and outstanding mechanical properties. Preferred co-reactants are polyacrylate or polyester polyols.

The main applications for systems based on Starlite 3390 BA/SN are air- and force-drying coatings for automotive OEM, automotive refinishing, transportation, industrial finishing and plastics.

 

Storage 

Storage in original sealed Starlite Painrs container.

Recommended storage temperature: 0 – 30 °C.

Protect from moisture, heat and foreign material.

General information: the product is sensitive to moisture. Storage at higher temperatures will result in increase of color and viscosity.

 
Storage time

Starlite Paints represents that, for a period of six months following the day of shipment as stated in the respective transport documents, the product will meet the specifications or values set forth in section “specifications or characteristic data” above, whatever is applicable, provided that the product is stoed in full compliance with the storage conditions set forth in and referenced under section “storage” above and is the otherwise handled appropriately.

Safety 

Hazards identification

Flammable. may cause sensitization by skin contact. Harmful to aquatic organism, may cause long-term adverse effects in the aquatic environment. Contains isocyanates. See information supplied by the manufacturer.

The product is used mainly as a hardner in coating materials or adhesives. The handling of coating materials or adhesives containing reactive polyisocyanates and residual monomeric HDI requires appropriate protective measures referred to in the safety data sheet. These products may therefore be used only in industrial or trade applications. They are not suitable for use in homeworker (DIY) applications.

The safety data sheet should be observed. This contains information on labeling, transport and storage as well as on handling, product safety and ecology.
