Oil Soluble Blue - Frequently Asked Questions
Q: What is the recommended dosage of Oil Soluble Blue in plastic applications?
A: The typical usage level ranges from 0.01% to 0.5% by weight, depending on the desired color intensity and base material. For PVC applications, we recommend starting with 0.05% concentration and adjusting based on specific requirements. Always conduct small-scale trials to determine the optimal dosage for your formulation.
Q: How does Oil Soluble Blue perform in outdoor applications?
A: Oil Soluble Blue exhibits excellent weatherability with a lightfastness rating of 7-8 on the Blue Wool Scale. Under standard testing conditions (ISO 105-B02), it shows minimal color fading after 500 hours of xenon arc exposure. For best results in outdoor applications, we recommend combining with appropriate UV stabilizers in the formulation.
Q: Can Oil Soluble Blue be used in food contact applications?
A: Our standard Oil Soluble Blue is not food-grade approved. For food contact applications, we recommend using our specially formulated food-grade colorants that comply with FDA 21 CFR regulations. Always verify regulatory compliance for your specific application and jurisdiction before use.
