Review: A MOST EXCELLENT PRODUCT - This is what you want for anchoring glass security film. Apply the film you want, let dry (at least we did) about 2 weeks, then apply this around the edge where the film meets the edge of the panel and anchor the security film in place. Nice. Really enhances glass security film performance. Review: Probably the best Structural Sealant you can get. - Used this for the wall expansion joints on the exterior of my home. Also used this to cosmetically address the corner cracks of my foundation slab. Pros: Name you can trust, highly recommended by tradespeople I spoke to. Cons: It requires manual labor to apply, it is not free. ## Features - Dow Corning 995 Silicone Structural Sealant is a one-component, self-priming, shelf stable, neutral cure, elastomeric adhesive specifically formulated for silicone structural glazing. - Dow Corning 995 Silicone Structural Sealant exhibits the following unique features: excellent unprimed adhesion to most common building substrates, including glass, reflective glass, anodized aluminum, granite and paints, including most fluoropolymer-based paints; non-corrosive by-products; 20-year performance warranty available; cures to an extremely tough elastomeric rubber. - Color: Gray. - Contents of Cartridge : 10.3 fl oz (305 ml). - Minimum Order: 1 Each. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004M6A2V0 | | Best Sellers Rank | #337,429 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #505 in Silicone Adhesives | | Brand | Corning | | Brand Name | Corning | | Color | Gray | | Compatible Material | Metal | | Customer Reviews | 5.0 out of 5 stars 22 Reviews | | Item Form | Liquid | | Item Weight | 0.01 Ounces | | Manufacturer | Dow Corning | | Material | Silicone | | Material Type | Silicone | | Model | 43237-2 | | Number of Items | 1 | | Part Number | 43237-2 | | Style | Compact | | Style Name | Compact | | Surface Recommendation | Window, Door | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** Corning - **Item Weight:** 0.01 Ounces - **Material:** Silicone - **Style:** Compact - **Water Resistance Level:** Waterproof ## Images ![Dow Corning 995 Silicone Structural Sealant - Gray - Image 1](https://m.media-amazon.com/images/I/31Y30j1RQ7L.jpg) ## Questions & Answers **Q: is it paintable?** A: HelloAccording to the specifications, the Dow Corning 995 product should not be used in applications "where painting of the sealant is required, as the paint film may crack and peel". Thank youTechnologyLK Customer Service Team **Q: Can this be used to mount a small plastic plate to a shingle roof?** A: I would think so, I use this as an attachment system for security / ballistic film that is applied to glass and it’s frame. It is extremely durable and very difficult to remove. Once it is applied to any material it’s produces a very strong bond. Hope this helps.
