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 provides excellent adhesion to non-porous substrates such as glass, aluminum, and ceramics without the need for a primer. Engineered to withstand extreme temperatures ranging from -60°F to 400°F, it remains permanently flexible with a ±25% joint movement capability. Its UV-resistant and weatherproof formula ensures a long-lasting, watertight seal for both interior and exterior projects, including skylights, solar panels, and HVAC ductwork.

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.

Any and all prices are subject to change without notice. We will always bill you at current prices prevailing at the time of shipment (excluding backorders). Availability of product can change at any time. We receive products daily and the availability may not always reflect what is in stock.
