OSI HM270 Construction Silicone Sealant is a professional-grade, one-part RTV silicone designed for high-performance glazing and sealing applications. This medium-modulus sealant cures at room temperature upon exposure to atmospheric moisture, forming a durable, watertight bond that remains permanently flexible with up to 25% joint movement. Engineered specifically for non-porous surfaces, it provides excellent adhesion to glass, ceramics, aluminum, and primed steel, typically without the need for a primer. The formula is highly resistant to ultraviolet light and extreme temperatures ranging from -76°F to 350°F, making it ideal for exterior curtain walls, skylights, and solar panel installations. It features easy extrusion in various weather conditions and is virtually unaffected by harsh environmental elements.

General Ledger Coding

General Ledger Coding is a value added service provided for you at no additional cost.

General Ledger Coding makes accounting easier by providing you with a calculated total of purchases based on your General Ledger Codes.

In addition to traditional General Ledger Summary provided at time of invoice, we can also provide quotes and order acknowledgements with General Ledger Coding as well. We also give you the ability to change a GL Code for one or all items for renovation projects that may utilize a single GL Code. We can also code any of our "extended inventory" items with your General Ledger Code at the time of quote, order confirmation and invoicing as well. We can code our item numbers directly to your GL Codes should our item categories not align directly with your GL Code Categories.

Please contact us if you wish to implement our General Ledger Coding feature.
