How hard and strong is cured Superfast Plastic per the TDS?
Shore D hardness is 65 after the full 24-hour cure. Lap shear strength on plastic is 2.4 MPa and compressive strength is 69 MPa. Density is 1.6 g/cm³. Typical properties are for information only, not specification limits.
What service temperatures does Sylmasta Superfast Plastic support?
Continuous service is listed to 120°C and intermittent service to 150°C. Store unused stick out of direct sunlight in dry, frost-free conditions between 15°C and 20°C for a 24-month shelf life from manufacture.
Will cured Superfast Plastic rust, shrink, or pull away?
No. Superfast Plastic does not rust, will not shrink or pull away when setting, and is resistant to water, chemicals, and temperature extremes. The epoxy contains no solvents or VOCs and is non-flammable.
Can finished Superfast Plastic repairs be machined or painted?
Yes. Cured material sets off-white and can be tapped, drilled, sawed, machined, ground, filed, or painted. Unused epoxy stays fresh for future cuts when kept in original packaging.
