Product Description

General description:

Chemical Formula: C16H30O4Sr

Strontium Octoate is replacement of Lead Octoate, where Lead free Paint/Ink is required. It improves through drying in adverse effect like high humidity & low temperatures.

Application & Usage:

Driers such as calcium octoate can be used to minimise or prevent loss of dry by becoming preferentially adsorbed onto the surface of the pigments instead of the active metal drier.
In making a paint, it is good practice to add the calcium drier first, before the other driers in order to maximize its effectiveness.

Efficient Drier for Coatings

Strontium Octoate serves as a superior drier in alkyd-based paints, varnishes, and coatings, optimizing the drying process and improving the overall finish. Its ability to enhance both gloss and hardness makes it a valuable additive in many industrial applications. It is often used in synergy with Cobalt driers for improved results.

Safe and Stable Storage

This liquid drier is stable under normal storage conditions and is not classified as hazardous in typical industrial settings. Proper storage involves keeping the product in tightly sealed containers, away from direct sunlight, within cool and dry environments. When stored correctly, Strontium Octoate has a reliable shelf life of 12 months.

FAQs of Strontium Octoate:

Q: How is Strontium Octoate used in the coatings industry?

A: Strontium Octoate is primarily employed as a drier in alkyd-based paints, varnishes, and coatings. It accelerates the oxidative curing of these products, improving both gloss and surface hardness. It is typically incorporated in concentrations of 0.050.5%, based on strontium metal content, and often used alongside cobalt driers.

Q: What benefits does Strontium Octoate offer compared to other metal driers?

A: This product provides a balanced drying action without excessive yellowing, enhances gloss and hardness in coatings, and is compatible with most alkyd resins. Its mild odor and non-hazardous classification further facilitate handling and application.

Q: When should Strontium Octoate be added during the paint formulation process?

A: Strontium Octoate is generally added during the final blending stage of paint production, after mixing the main binder and pigments, to ensure optimal performance and uniform distribution in the finished product.

Q: Where should Strontium Octoate be stored to maintain its stability?

A: It should be kept in tightly closed HDPE barrels in a cool, dry, and well-ventilated area, away from direct sunlight and sources of moisture. Proper storage preserves its quality and ensures a shelf life of up to 12 months.

Q: What is the process for determining the correct dosage of Strontium Octoate in coatings?

A: The recommended dosage varies according to the formulation and requirements of the end product, typically within 0.050.5% based on metal content. Laboratory testing or manufacturers guidelines should be followed to optimize drying time and coating performance.

Q: Is Strontium Octoate hazardous to use or store?

A: Strontium Octoate is not classified as hazardous under normal storage and usage conditions. It is non-poisonous, has a mild odor, and does not require special handling beyond standard industrial practices for chemical storage.
