Organic Silicon Surface Additive for Reducing the Surface Tension Composition IR-108Polyether modified polydimethylsiloxane solution (equivalent to BYK-306)Typical Properties Density at 20℃, g/mlNon-volatile mater, %Flash point, ℃IR-1080.9312.525Solvents: xylene /ethylene glycol monophenyl ether 7/2These properties are provided as typical properties, NOT THE PRODUCTS TECHNICAL INDEX.Proposed Dosages Dosage based upon total formulation, %IR-1080.1-0.5The above recommended dosages strongly depend on pigment particle size. Optimal dosages should be calculated in the laboratory according to different formula.Addition Methods&Process Technology Instructions These additives can be added during any production stage, including post-addition. To add convenient (especially with IR-133), auxiliaries can be diluted by suitable solvent at first.Functions These additives provide strong reduction in surface tension of paint systems, especially to improve substrate wetting and avoid cratering. Additionally, surface slip and gloss are increased.Compared to silicone oils, these additives are used friendly. However, please test the foam stability through a series of experiments before use. In addition, it is also necessary to assess its recoatability and shinkage cavity tendency.Applications Solvent-borne systemsSolvent-free systemsAqueous systemsIR-108RecommendedSuitableSuitable Special Features IR-108 is a highly effective silicone additive for wetting critical substrates. It can improve the acceptance of dust and spray dust, and form thicker film in the vertical plane. IR-108 can reduce the air sensitivity of wood and furniture coatings. It also improves flatting agent orientation.Package and Storage Packed in iron drums of 25 or 200kg net each. Validity period is 12 months in sealed containers.Special Notes Separation or turbidity may occur if the temperatures below 5°C.
