406 Colloidal Silica - West System

406 Colloidal Silica is an epoxy thickening additive used to control the viscosity of the epoxy. It prevents epoxy runoff in vertical and overhead joints. This is a very strong filler. It creates a smooth mixture, ideal for general epoxy bonding and filleting. It is also our most versatile epoxy filler. Often used in combination with other fillers, 406 can be used to improve strength, abrasion resistance, and consistency of epoxy fairing compounds. The result is a tougher, smoother surface. 4 oz. squeeze bottle Color: off-white.

G/Flex 650 Toughened Epoxy

G/flex 650 is a toughened, versatile, liquid epoxy for permanent waterproof bonding of fiberglass, ceramics, metals, plastics, damp and difficult-to-bond woods. With a modulus of elasticity of 150,000 PSI, it is a bit more flexible than standard epoxies and polyester, but much stiffer than adhesive sealants. This gives it the ability to make structural bonds that can absorb the stress of expansion, contraction, shock, and vibration. It is ideal for bonding dissimilar materials. It can be modified with WEST SYSTEM fillers and additives and used to wet-out fiberglass tapes and fabrics. Mixed at a 1:1 ratio, this 2-part epoxy gives you 46 minutes of pot life at 72°F and an open (working) time of 60-75 minutes. It reaches an initial cure in 3 to 4 hrs and a workable cure in 7-10 hours. 2 - 4oz. bottles / kit
