Of course when using it for bonding the only problem is the length of time needed to cure; for handling there is a wait of 8 hours and full strength isn’t attained until the 24 hour mark is reached. To best take advantage of its strength use it to fillet already formed joints. It can be mixed with micro-balloons to form a putty-like consistency which is ideal for the task, although using this technique does slow down the curing time, by around 25%. Slow-Cure bonds best to clean, textured surfaces. Smooth, non-porous surfaces should be roughened with coarse sand paper to improve adhesion. Acetone and Isopropyl rubbing alcohol work as the best solvents for cleaning uncured epoxy from surfaces. ## Features - BSI Slow Cure 30 Minute Epoxy Glue ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0166FFFS4 | | Best Sellers Rank | 88,392 in DIY & Tools (See Top 100 in DIY & Tools) 371 in Universal Adhesives | | Brand | Bob Smith Industries | | Colour | Transparent/Green | | Compatible Material | Fibreglass | | Container Type | Bottle | | Customer Reviews | 4.7 4.7 out of 5 stars (3,054) 4.7 out of 5 stars | | Full Cure Time | 3E+1 Minutes | | Included Components | One 2.25 oz bottle of Epoxy and one 2.25 oz bottle of Hardener | | Item Form | Liquid | | Item Package Quantity | 1 | | Item Volume | 130 Millilitres | | Item Weight | 0.1 Kilograms | | Manufacturer | Bob Smith Industries | | Manufacturer Part Number | BSI-205 | | Material | Epoxy Resin | | Model Number | BSI-205 | | Number Of Pieces | 1 | | Other Special Features Of The Product | High Strength, Waterproof, Versatile Bonding | | Specific Uses For Product | Bonding, Forming reinforcing fillets, General adhesive purposes, Woodworking, Metalworking, Fiberglass repair | | Tensile Strength | 4500 Pounds Per Square Inch | | Unit Count | 127.5729 gram | | Upc | 354123445706 007336205000 707336205085 707336205009 | | Viscosity Level | Medium to High | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** Bob Smith Industries - **Item form:** Liquid - **Material:** Epoxy Resin - **Special feature:** High Strength, Waterproof, Versatile Bonding ## Images ![BSI Slow Cure 30 Minute Epoxy Glue (128g) - BSI205 - Image 1](https://m.media-amazon.com/images/I/51POalvT6cL.jpg) ## Available Options This product comes in different **Colour Name** options. ## Questions & Answers **Q: Can I use this Epoxy for adhering stones for jewelry** A: Yes, but it will tend to not work as well for larger stones glued to flat surfaces. My wife makes glass jewelry and swears by E6000 silicone **Q: Is the consistency runny enough to use for sealing the end grain of exterior wood?** A: I haven't tried it for sealing end grain. That said, I would expect it to work. Just watch your cure time; the BSI-205 gets an initial set after some 30 minutes, but may need 12 or more hours to develop a full set. Double-check the instructions for set time. **Q: Does this bond metal and wood together?** A: Yes it will bond wood and metal together. Works best when either material is scuffed up a bit. Russ-Pen Kit Mall **Q: Can this be use for filling dings on electric guitar basses? Can it then be sanded down to mirror like finish?** A: Epoxy can be used to fill dings on almost anything. Epoxy can be sanded once it's cured. To get a mirror-like finish might require some kind of coating- paint, polish? Good Luck! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Quality Epoxy *by on Reviewed in the United Kingdom 14 June 2026* Very strong long open epoxy, I needed to set some knife blanks into wooden handles and this worked very well when left overnight to cure. Easy to mix up in small amounts and dries with a very clean finish, any excess is easy enough to wipe away when applying. ### ⭐⭐⭐⭐⭐ Great stuff *by on Reviewed in the United Kingdom 16 January 2026* It repaired a broken ceramic bird bath with no problem. You get plenty of time to adjust the piece before it starts to cure, and once it has it's secure and hard as steel. ### ⭐⭐⭐⭐⭐ Excellent Epoxy product. *by on Reviewed in the United Kingdom 28 November 2025* An excellent high quality Epoxy product which works perfectly. The packaging is well made too and after use you can store it back inside. Just carefully pull down the rear flap of the pack to open, no need for scissors to open.I use mainly for RC models and small repair jobs round the house.I would highly recommend to anyone wanting a top quality Epoxy product. ## Frequently Bought Together - Bob Smith Industries BSI-205 Clear Slow-Cure Epoxy (4.5 oz.
