The Sylmasta Superfast Plastic Epoxy Putty Stick is a high-performance, fast-setting epoxy repair compound engineered for maintenance professionals who need dependable, permanent repairs without downtime. Each stick contains pre-measured portions of resin and hardener blended throughout, eliminating the need for mixing tools or guesswork. Simply cut off the required amount, knead by hand, and apply directly to the damaged surface.
Designed specifically for plastic repair, this epoxy putty bonds to most major plastic types — excluding polyethylene and polypropylene — and also adheres well to metals, masonry, wood, and glass. It’s ideal for sealing leaks in PVC and ABS pipes, reconstructing broken parts, or making fast structural fixes in industrial and facility maintenance settings.
Supplied as a kit with multiple 114g (4 oz) sticks, Superfast Plastic is compact, clean to handle, and easy to store. It cures quickly, forming a durable, non-rusting, and machinable repair that can be drilled, sanded, or painted. Its non-shrinking formulation and resistance to water, chemicals, and temperature extremes make it a trusted solution for both routine repairs and emergency fixes in the field.

Frequently Asked Questions
What plastics does it not work on?
Superfast Plastic does not bond effectively to polyolefins such as polyethylene (PE) or polypropylene (PP).
Can it be used on wet surfaces?
For best results, surfaces should be dry. However, once cured, the product is waterproof and suitable for wet environments.
How long does it take to fully cure?
Initial hardening occurs within 35–40 minutes. It can usually be returned to service after 2–3 hours at room temperature.
What is the maximum temperature it can handle?
It withstands up to 250°F (120°C) continuously and 300°F (150°C) intermittently.
Is any surface prep required?
Clean and roughen the surface to improve adhesion. Gloves are recommended when handling the uncured epoxy.
What is the shelf life?
When stored in dry, room-temperature conditions, shelf life is 18 months from the date of manufacture.
