Spabond 340 Epoxy Adhesive System n Excellent gap filling properties n High strength and toughness industrial adhesive n Three hardener speeds to give a range of working times / clamp times n Low exotherm and shrinkage n Temperature performance up to 80°C Introduction Spabond 340 is a toughened, thixotropic adhesive system with a simple 2:1 by weight and by volume mix ratio. It is designed for use with a mixing machine and has a sag resistance of 30mm on a vertical surface. The range of hardeners available make this product ideal for bonding small or large structures. The components are pigmented to give a visual indication of mix quantity.

Spabond 340 resin should be combined with any one Spabond 340 hardener in the following mix ratio: Instructions for Use Working Conditions The product is optimised for use at 15 - 25°C. At lower temperatures the components thicken and may eventually become unworkable. To ensure accurate mixing and good workability pre-warm the resin & hardener as well as the surfaces to be bonded before use. Surface Preparation Before using the product ensure that surfaces to be bonded are clean, dry and dust-free. Prepare all surfaces by abrading with medium grit paper or other suitable abrasive, remove...

Transport & Storage The resin and hardeners should be kept in securely closed containers during transport and storage. Any accidental spillage should be soaked up with sand, sawdust, cotton waste or any other absorbent material. The area should then be washed clean (see appropriate Safety Data Sheet). Adequate long term storage conditions will result in a shelf life of two years for both the resin and hardeners. Storage should be in a warm dry place out of direct sunlight and protected from frost. The temperature should be between 10°C and 25°C. Containers should be firmly closed....
