Review: Maybe not what I needed - Bought this to retain pin in a revolver which was walking out when shooting. Didn't want to stake the pin. This didn't work even after 2 attempts and cleaning prep. Ended up using clear finger nail polish Review: Not sure what to expect - Haven't used it yet but it had a sticker covering up a label that said for sale in India only. ## Features - Applicable Materials - Most Metals - Capacity Vol. - 50 mL - Chemical Compound - Acrylic - Color - Yellow - Curing Method - Anaerobic ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000O01EG0 | | Brand | Loctite | | Brand Name | Loctite | | Color | Red | | Compatible Material | Ceramic, Plastic | | Container Type | Bottle | | Customer Reviews | 4.2 out of 5 stars 29 Reviews | | Full Cure Time | 24 Hours | | Global Trade Identification Number | 00079340214583 | | Item Form | Liquid | | Item Package Quantity | 1 | | Item Weight | 0.18 Pounds | | Manufacturer | Loctite | | Material | Acrylic | | Material Type | Acrylic | | Model | 641 | | Number of Pieces | 1 | | Other Special Features of the Product | Controlled Strength | | Part Number | 442-21458 | | Special Feature | Controlled Strength | | Specific Uses For Product | Retaining cylindrical parts that require disassembly | | UPC | 079340214583 | | Unit Count | 1.7 Fluid Ounces | | Viscosity Level | Medium | | Volume | 50 Milliliters | | Water Resistance Level | Not Water Resistant | ## Product Details - **Brand:** Loctite - **Material:** Metal - **Item Form:** Liquid - **Color:** Red - **Item Package Quantity:** 1 ## Images ![SEPTLS44221458 - Loctite 641 Retaining Compound, Controlled Strength - 21458 - Image 1](https://m.media-amazon.com/images/I/71fBQx-3GBL.jpg) ## Customer Reviews ### ā­ā­ā­ā­ Maybe not what I needed *by R***P on June 21, 2024* Bought this to retain pin in a revolver which was walking out when shooting.
