Our Duratec Crystal Clear Sealer is a low viscosity, rapid
curing sealer that penetrates deeply allowing a solid anchor for
lacquers, urethanes, polyesters, vinyl esters, and most epoxies
to a variety of substrates.
FEATURES
EASY TO APPLY
Spray, r oll, or brush on as your
application s ees fit.
RAPID C URING
Surfaces are ready for topcoats in
one to two hours – some even
fas
ter with no need to wait!
DEEP PENETRATION
Low v
iscosity allows sealer to
penetrate surfaces for a more
c
omplete seal.
HIGH COMPATIBILITY
Versatile t o work with your
substrate and your choice in
topcoat lacquers
, urethanes,
polyesters, viny
l esters, a nd most
epoxies.

SAFETY & HANDLING
Duratec Crystal Clear Sealer is extremely flammable. Do not apply near sparks,
open flames or heat. Keep area ventilated. Do not smoke. Avoid continuous
breathing of vapor. Duratec Crystal Clear Sealer contains ingredients which could
be harmful if mishandled. Contact with skin and eyes should be avoided and
necessary protective equipment and clothing should be worn. Individuals should
wash with soap and water before eating or drinking. All containers should be
properly labeled to prevent accidental ingestion or improper disposal. Individuals
should reseal any partly used material back in the container. Store under cool, dry
conditions and away from open flames and high temperatures.
For more detailed instructions on storage, please see the MSDS sheet.

Prepare
T
emperature should be at least 64 F. Low temperatures extend cure time.
Ensure the surface is clean and free of both chemical and environmental contaminants. If needed,
slightly sand the surface with 120-220 grit and then wipe off surface with a clean (not tack) rag.
Thoroughly stir the Duratec Crystal Clear Sealer in the can prior to catalyzing.
Catalyze Crystal Clear Sealer with a full strength MEKP, like Norox 925. Catalyst ratio is 2% by weight.
Due to the rapid gel time, mix only the amount that can be applied within 15-18 minutes.
NOTE: Higher temperatures yield a shorter pot life and gel time, while lower temperatures yield a
longer pot life and gel time.
Apply Sealer
Roll, brush, or spray the sealer on. If spraying, apply using air-assisted or airless spray at lowest
practical pressure. Wipe away any excess using a clean white cloth or paper towel. Do not use tack
rag.
Topcoating (Urethane, Polyester, Vinyl Esters)
In general, sealer will be ready to topcoat within an hour or two, but may be ready faster depending
on amount of sealer used and ambient temperature.
Sanding the sealer prior to
topcoating is not necessary if the time between sealing and topcoating is
less than eight hours. If more than 8 hours have passed, we suggest sanding with 180-200 to provide
mechanical tooth for the bond.
Topcoating (Epoxy)
Adhesion between the Duratec Crystal Clear Sealer and epoxy is dependent on a mechanical bond
with the epoxy rather than a chemical bond. We advocate for a cure time of at least eight hours.
Abrade the surface with sandpaper (180-220) prior to topcoating with epoxy.
The following use instructions are broad to address multiple applications. We recommend testing for product
compatability with your process. Please contact our Tech Team at (909) 546-1160 with any questions.
