Why is my epoxy flexible?
Resin needs more time to cure While a resin is curing, it will no longer be liquid, but can be soft and pliable.
If this is happening to you, double check the cure time for your resin.
With any luck, you simply need to give it more time to dry..
What happens if you don’t use enough hardener resin?
Off ratio: Too much or too little hardener will affect the cure time and thoroughness of the cure. Remove epoxy. Do not apply additional material over non-curing epoxy. … DO NOT add extra hardener for a faster epoxy cure!
Is epoxy permanent?
Epoxy is a permanent adhesive used on many types of surfaces, from plastic to metal. Once epoxy has hardened, removing it can be tricky. Epoxy starts in a liquid state. … Removing epoxy can be accomplished relatively easily, as long as you take the proper safety precautions and are patient.
How long does marine epoxy take to dry?
24 hoursSupport parts until bond sets (approx. 120-150 minutes at room temperature). Allow full cure of 24 hours before subjecting to normal use. Moderate heat will speed hardening while cooler temperatures will require a longer set time.
Is there a flexible epoxy?
Flexible Epoxy Resins for Higher Solids. … 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.
What is marine grade epoxy?
MAX MARINE GRADE Epoxy Resin is a two-part epoxy/polyamide resin system specially formulated to provide structural strength to a variety of marine and boat building use such as structural fiberglassing, waterproofing, and high strength bonding application.
Why is my epoxy not hardening?
If your resin hasn’t cured properly, this means that the chemical reaction between the resin and hardener was not able to take place. … Try moving your piece to a warmer spot: if it doesn’t dry, re-pour with a fresh coat of resin.
How thick can you pour West System epoxy?
While it is a slower curing system, it still should not be poured more than ¼” deep at a time. We have found that building up castings ¼” at a time allows the epoxy to cure without overheating.
Is polyester resin flexible?
Polyester resins are typically low strength unless used with a reinforcing material like glass fibre, are relatively brittle unless reinforced, and have low adhesion. Epoxies, by contrast, are inherently strong, somewhat flexible and have excellent adhesion. However, polyester resins are much cheaper.

Which epoxy is best for plastic?
Loctite. Several of Loctite’s well-known adhesives are formulated to work especially well with plastic. Its Plastics Bonding System offers the resin and activator of an epoxy in small, separate tubes with precise applicators, making it an excellent choice for jobs that require a degree of delicacy.
Which is the strongest glue for plastic?
Loctite Plastics Bonding SystemFor the strongest glue to use on harder plastics try Loctite Plastics Bonding System, a two-part cyanoacrylate adhesive. It’s water-resistant, sets in seconds with minimal application, and dries clear.
Is epoxy stronger than Gorilla Glue?
As a material, hardened epoxy is stronger than the polyurethane that makes up Gorilla Glue, but again, that doesn’t matter in actual use.
Is epoxy stronger than fiberglass?
Epoxy resin can be as much as 35% stronger than the resin used on a fiberglass board. … An epoxy surfboard has better buoyancy than a fiberglass board, making it easier to paddle, float, and ultimately catch waves, making them a great choice for those surfers just starting out.
Is 2 part epoxy flexible?
Two-part epoxy adhesives range in performance from rigid to flexible, including some toughened formulations designed for fatigue resistance. Like one-part epoxy adhesives, they are resistant to extremes of heat, cold, humidity, many solvents and other conditions.
Why is my resin not clear?
Foggy resin projects can happen for a few reasons: Make sure the mold is clean and completely dry before pouring. The mold can play a part in the finish. If the surface of your mold is shiny, the resin will be shiny. This silicone mold is very matte, therefore the resin turned out dull and matte.
Does epoxy stick to PVC?
Occasionally our customers ask about using WEST SYSTEM® Epoxy to bond PVC (polyvinyl chloride) plastic to another surface. Typically, traditional epoxy doesn’t adhere well to many plastics due to a lack of surface texture for a mechanical bond.
Can I use Gorilla Glue on plastic?
Gorilla Glue will work well on many types of plastic; however, we do not recommend for use on polypropylene (PP) or polyethylene (PE) plastics or any type of rubber with high oil or plasticizer content.
Does epoxy go bad?
WEST SYSTEM resins and hardeners do no have a strict shelf life. Certain changes may make them less effective for some jobs, but the resin and hardener will still be reactive. … The “expiration dates” on our containers are 2 years from the date of manufacturer, but actual shelf life is typically far longer.
