Ir-133 Polyether Modified Polydimethylsiloxane
Organic Silicon Surface Additive for Reducing the Surface Tension Composition IR-133Polyether modified polydimethylsiloxane (equivalent to BYK-333)Typical Properties Density at 20℃, g/mlNon-volatile mater, %Flash point, ℃IR-1331.04>97>100These properties are provided as typical properties, NOT THE PRODUCTS TECHNICAL INDEX.Proposed Dosages Dosage based upon total formulation, %IR-1330.05-0.3; in aqueous and UV systems can up to 1The 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, 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-133RecommendedRecommendedRecommended Special Features IR-133 is common to all paint systems. It can strongly increases surface slip and considerably improve substrate wetting. In aqueous systems, it could improve blocking resistance. Additionally, IR-133 displays excellent compatibility and can be used as an anti-cratering additive.Package and Storage Packed in iron drums of 25 or 200kg net each. Validity period is 12 months in sealed containers.Special Notes Heat up to 20℃ and mix well before use.
