The grip strength is serious — once it sets, things aren’t moving. Perfect for press-fit or cylindrical parts. Just make sure alignment is right before it cures, because it’s not forgiving. Definitely worth it for long-term reliability Review: Strong stuff - Looks like the real deal. Although when you peel the sticker back it reads "For India Only". My 242 bottle had the same and it is working like it should. This 638 is strong stuff. ## Features - Approvals: Canadian Food Inspection Agency (CFIA) - Item Package Length: 5.99999999388" - Item Package Width: 1.99999999796" - Item Package Height: 1.099999998878" ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000O01EV0 | | Best Sellers Rank | #13,644 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #5 in Retaining Compounds | | Brand | Loctite | | Color | Green | | Date First Available | April 4, 2007 | | Department | Unisex Adult | | Full Cure Time | 5 Minutes | | Global Trade Identification Number | 00079340006393, 00079340214484 | | Is Discontinued By Manufacturer | No | | Item Form | Liquid | | Item Package Quantity | 1 | | Item Volume | 50 Milliliters | | Item Weight | 2.88 ounces | | Item model number | 21448 | | Manufacturer | Loctite | | Package Information | Bottle | | Product Dimensions | 1 x 1 x 12 inches | | Special Feature | Green | | Specific Uses For Product | Repair | | UPC | 079340214484 079340006393 | | Unit Count | 1.69 Fluid Ounces | | Viscosity | 2500.0 mPa*s (cP) | | Viscosity Level | Medium | | Water Resistance Level | Not Water Resistant | ## Product Details - **Brand:** Loctite - **Color:** Green - **Item Form:** Liquid - **Special Feature:** Green - **Specific Uses For Product:** Repair ## Images ![21448 Green 638 High Strength Retaining Compound, 50 mL Bottle - Image 1](https://m.media-amazon.com/images/I/81lbCjVCb4L.jpg) ## Questions & Answers **Q: How much should a new bottle weigh?
