Methyl ethyl ketone peroxide (MEKP) is an organic peroxide with the formula [ (CH 3) (C 2 H 5)C (O 2 H)] 2 O 2. MEKP is a colorless oily liquid. It is widely used in vulcanization (crosslinking) of polymers. [3] It is derived from the reaction of methyl ethyl ketone and hydrogen peroxide under acidic conditions.

MEKP hardener is a 50 % solution of methylethylketoneperoxide in a desensitised plasticizer. It is used in combination with cobalt accelerators for the cold curing of polyester resins. The MEKP hardener/cobalt accelerator system has medium activity and leads to uniform, low-stress hardening of the resin.

Polymer Imported Methyl Ethyl Ketone Peroxide (MEKP) Hardener – Polymer Products (Phils.) Inc. Higher concentrate, waterless type of MEKP. Mix thoroughly into pre-mixed resin 1-2% by …

MEKP is a clear hardener/catalyst for the room temperature cure of unsaturated polyester and vinyl ester resins. It is also needed with all gel coats. It is typically used between 1.25% to 1.75% (1 2/3 ounce to 2 1/3 ounces per gallon). Resins that have Duratec in their name require a 2% mix ratio (2 2/3 ounces per gallon).

MEKP (Methyl Ethyl Ketone Peroxide) is a catalyst used in the composites industry for polyester and vinyl ester resins and gel coats. It reacts with resin to turn it from a liquid to a solid (cure it).

Each resin product is available as a kit with the correct amount of hardener. However, hardener may be purchased individually. Phthalate free MEKP offers the greatest flexibility in terms of useful concentration range and pot-life thus finds use in a wide variety of ambient temperature cure application.

HP-MEKP is a methyl ethyl ketone peroxide hardener for curing unsaturated polyester resin at ambient temperature. Universally usable for unsaturated polyester resins from product line HP-P21, other polyester resins do need tests beforehand!

MEK Peroxide (Methyl Ethyl Ketone Peroxide) is the catalyst of choice for polyester resins, casting, tooling, vinyl ester, ISO resins, and gelcoats. When this catalyst is mixed with the resin or gelcoat, a powerful chemical reaction takes place, generating heat …

R10-103 Pre Mixed Polyester Resin with PPP Mekp – Polymer Products (Phils.) Inc. A general purpose, semiflexible polyester resin used primarily with fiberglass reinforcements. Also used to make glass reinforced plastic products which require some resiliency for greater toughness and impact resistance such as boats, car bodies, tanks, etc.

2024年7月22日 · Methyl ethyl ketone peroxide (mekp) is a liquid chemical compound from the family of ketone peroxides that it is used to initiate the polymerization of unsaturated polyester and vinylester resins at different curing temperatures.
