How strong is G Flex?
G/flex is resilient and impact resistant. With a modulus of elasticity of 150,000 psi (WEST SYSTEM 105 Resin/205 Hardener has a modulus of elasticity of 450,000 psi), G/flex is more flexible and can deflect further before breaking than WEST SYSTEM 105/205, while being much stiffer than typical adhesive sealants.
How long does G flex epoxy last?
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.
Can you fiberglass over G Flex?
G/flex is ideal for bonding a variety of other materials, in- cluding dissimilar ones—metals, plastics, glass, ma- sonry, and fiberglass. It can be used to wet out and bond fiberglass tapes and fabrics.
Does West System epoxy bond to aluminum?
Adhesion to aluminum can best be im- proved by treating it with the two-part WEST SYSTEM 860 Aluminum Etch prior to apply- ing the epoxy. Aluminum can be prepared using the “abrade through wet epoxy” method with good results if an Aluminum Etch kit is not available.
Is West System epoxy waterproof?
But since WEST SYSTEM Epoxy is very strong and an excellent adhesive, it strengthens the wood and makes it waterproof.
Can G Flex be sanded?
When cured, G/flex 655 can be sanded, sawn, nailed and screwed. made with thermoformed plastics like HDPE (high-density polyethylene), ABS, and occasionally PVC. G/flex adheres to these materials with specific surface preparations.
Is there a flexible epoxy?
EPON™ Resin 872 is an epoxy resin modified for flexibility and toughness, useful in applications where thermal shock or impact must be withstood. EPON Resin 872, 873 and 874 series modified epoxy solutions at 75-90% solids are also available.
Do you sand between coats of epoxy?
First, sand down the entire surface of your piece with coarse sandpaper ( we use 80 grit sandpaper here at ArtResin ). Sanding epoxy resin between coats will not only get out the imperfection, but will also serve to provide some tooth between the first and second layers.
What is the shelf life of West System epoxy?
ATL Composites recommend that WEST SYSTEM® resin and hardeners should be kept in the original containers with the caps tightly sealed, and stored at room temperature (15oC to 32oC) to provide a 2 year shelf life from when the pack has been opened.
How many coats of epoxy should I use?
Most projects need between two and four. However many coats you’re planning on, you need to recoat at the right time and in the right way and ensure your surface is properly prepared.
Can you paint G Flex?
Cured G/flex can be varnished, painted, or recoated or bonded to with epoxy. Wash cured G/flex with water and sand surfaces to a dull finish, providing a texture for good adhesion.
How do I thin my G flex epoxy?
Thinning epoxy with heat. Heating the resin/hardener components and then mixing them together results in a thinned epoxy mixture that, when cured, retains all the characteristics of epoxy cured at room temperature.
What is G/Flex 650 used for?
This gives G/flex 650 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.
What is the difference between epoxy and G Flex 650?
G/flex 650 is a bit more flexible than standard epoxies and polyester, but much stiffer than adhesive sealants. This gives G/flex 650 the ability to make structural bonds that can absorb the stress of expansion, contraction, shock and vibration.
How long does it take for 650 G Flex to dry?
Mixed at a 1:1 ratio, G/flex 650 gives you 45 minutes of working time at 72°F. It reaches an initial cure in 7 to 10 hours and full cure in 24 hours. 650 G/flex Resins should be paired with comparable size 650 G/flex Hardeners. Includes 4 ounces of resin and 4 ounces of hardener. Drying Time: Initial cure: 6-10hrs.;
