DELTA-SC®2236 

DELTA-SC®2236 is a silicone surface additive with defoaming properties to improve the surface properties of coatings, with particular emphasis upon leveling, it increases surface slip and thus improves scratch and mar- resistance. DELTA-SC®2236 is a heat resistant due to the alkyl-modification, which shows no thermal decomposition at high temperatures in baking systems such as coil coatings (up to 280°C for 15 minutes). 


Specifications: 

Composition :Solvent-free modified polysiloxane 

Specific gravity @ 20°C :ca. 0.95 g/cm3 

Flashpoint :51°C 

Appearance :Transparent liquid 

Active ingredients :>98% 


Applications and usage: 

Coatings 

DELTA-SC®2236 is an alkyl-modified polysiloxane, soluble in aliphatic and aromatic hydrocarbons, esters and ketones, insoluble in water. 

DELTA-SC® 2236 improves the general surface characteristics and in particular the following advantages are gained: 

●    Improved levelling and surface smoothness 

●    Increased slip and mar-resistance 

●    Orange-peel effect and cratering are prevented 

●    The formation of Benard cells (anti-floating effect) is avoided 

●    Improved overspray acceptance 

●    Acts as a defoamer and de-aeration aid 

DELTA-SC®2236 is especially recommended for non-aqueous coatings. The alkyl-modification makes it act as a defoamer and slip agent. 

It is highly recommended in the following applications: 

●    Stoving enamels based on alkyd-, acrylic- or polyester resins 

●    Acid cured- or polyurethane- wood finishes particularly when applied by curtain coating 

●    Self-levelling epoxy flooring compounds 

●    UV-curable paper lacquers 

●    Air-dried alkyd systems 

It should be added during the final thinning. For ease of handling, dilute to 10% in aromatics or mineral spirits. 

0.05-0.5% on total formulation weight 


Safety and Handling: 

DELTA-SC®2236 should be handled in accordance with good industrial practice. Detailed information can be found in the Safety Data Sheet. 


Storage: 

DELTA-SC®2236 should be stored in a cool dry place. When kept in an original unopened container, it will keep up to 5 years from the date of manufacture. The production date is indicated on the container. 


Packaging: 

50 kg and 180 kg non-returnable metallic containers.
