Duratek Koruyucu Mad. San. ve Tic. A.S.

Epoxy and Polyurethane Based Products

Duratek has been specialized in polymer chemistry for 50 years. Duratek designs, produces and markets mainly epoxy, polyurethane and acrylic based materials. Duratek's sister company Paksoy Kimyevi / Kimar produces epoxy resins and hardeners (polyamines and polyaminoamides) totally independently with its own know how. This gives Duratek the advantage of starting to design a tailor made product from the raw material. Duratek produces certified lamination resins and adhesives for composites.

KL 790
HIGH Tg EPOXY LAMINATION SYSTEM

Suitable for hand lamination and filament winding techniques;
Curing at high temperature cycles is necessary: High Tg values (> 130oC) can be obtained;
Not a room curing system: can be used in large quantities, no pot life or no exothermic problems;
Parts like rocket body, shafts, pressure tanks, pipes and tubes, light masts, etc can be produced.

DURATEK 2400
MED. VISCOSITY EPOXY BASED FIBER LAM. RESIN

Mainly designed for centrifugal casting and filament winding processes, but it is also suitable for hand lay- up and vacuum assisted processes under certain conditions;
Pot life span and viscosity values are optimized for the best wetting of the fibers during centrifugal casting and filament winding;
Parts like rocket body, shafts, pressure tanks, pipes and tubes, light masts, etc can be produced;
Room temperature curing system;
High temperature resistance for a room temperature curing system: Tg > 120oC

Room temperature curing system.

KLM 474
EPOXY BASED WOOD LAMINATION ADHESIVE

KLM 474 is especially developed for wood lamination for keel and frame production. Its viscosity is already adjusted as an adhesive. Addition of any fillers on site is not necessary. KLM 474 has 1:1 mixing ratio by weight and volume, which makes it very easy to use. KLM 474 can be applied manually or by special dosing pumps. This glue also cures in moist settings. KLM 474 is certified by LR and successfully completed testing for Rina following the guidelines described by ISO 301.

GSM 874
LOW DENSITY EPOXY BASED PASTE (MANUAL APPLICATION)

GSM 874 is an epoxy based paste for modelling. This product is suitable for manual application.Other main characteristics: Low density (0,7 kg/lt); No sagging on vertical; Easy to level, does not accumulate on the trowel; Easy to sand; Highly elastic.

DURATEK 1000
EPOXY BASED LAMINATION RESIN (HLU & VB)
