Description of Epoxy HardenersAll working times(pot life) are based upon an optimum working temperature of about 80

degrees F. Temperatures variations will greatly affect curing times, and when below 65F can sometimes double curing times. Other factors that affect epoxy curing can be moisture and

humidity, as well as the thickness of lamination.

Description of Times Shown

Pot Life:  Represents the maximum amount of time that the mixture can remain in your pot. Once applied to your working surface(usually in thin layers) this will greatly increase the time you have before the epoxy sets.

Set Time:  This is the amount of time after the epoxy is applied in a thin film that it will arrive at a gel state, still wet, but no longer a liquid. To recoat without sanding between coats you must reapply after this point but before the drying time has completed.

Drying Time:  At this point the epoxy will be ready to sand and has reached about 90% of its cured hardness. Epoxy still might remain a bit flexible at this point but will complete 100% curing over the following 1-5 days. If air temperature get below 60 degrees, dry times can double from the times shown.

1 to 1 Epoxy Hardener for Laminating and Coating

For Use With Only 150 Thick Epoxy Resin

 

Mixing Ratio by Volume: 1:1

Pot Life: 30-35 Min @ 80F Set Time: 3-4 Hours Drying Time: 12-14 Hours

Generally used in combination with our thick resin for an excellent coating epoxy.

2 to 1 SLOW   Epoxy Hardener (#556)

Using this hardener provides for maximum working time at high temperatures. Ideal in high humidity conditions and temperatures over 85F.

Should not be used in conditions below 70F unless an extremely lengthy curing time is desired.

 

Mixing Ratio by Volume: 2:1

Pot Life: 35-40 Min @ 80F Set Time: 5-6 Hours Drying Time: 24-28 Hours

SlowNON-Blushing

3 to 1 MEDIUM Epoxy HardenerOur most popular hardener choice, an excellent general purpose hardener for most conditions

including high performance applications. Great for fiberglass and composite layup with carbon or

kevlar.

 

Mixing Ratio by Volume: 3:1

Pot Life: 20-25 Min @ 80F Set Time: 3-4 Hours Drying Time: 8-10 Hours

Medium

4 to 1 FAST Epoxy HardenerOur fast epoxy hardener is great for cold weather

conditions or for those who prefer fast curing times at normal temperatures. It is good for

fiberglass and composite layup as well as a fast cure bonding applications.

 

Mixing Ratio by Volume: 4:1

Pot Life: 15 Min @ 80F Set Time: 1-2 Hours

Fast

The faster cure of this particular hardener will also result in a more rigid laminate.

Drying Time: 3-4 Hours

Deskripsi Epoxy Hardeners

Waktu kerja (kehidupan pot) didasarkan pada suhu kerja optimum sekitar 80 derajat F. Suhu variasi akan sangat mempengaruhi kali menyembuhkan, dan ketika di bawah 65F kadang-kadang dapat melipatgandakan kali menyembuhkan. Faktor-faktor lain yang mempengaruhi epoxy curing dapat kelembaban dan kelembaban, serta ketebalan laminasi.

Deskripsi Times Tampil

Pot Life: Merupakan jumlah maksimum waktu yang campuran dapat tetap berada di pot Anda. Setelah diterapkan ke permukaan kerja Anda (biasanya dalam lapisan tipis) ini akan sangat meningkatkan waktu yang Anda miliki sebelum set epoxy.

Set Waktu: ini adalah jumlah waktu setelah epoxy diterapkan dalam film tipis yang akan tiba di negara gel, masih basah, tapi tidak lagi cairan. Recoat tanpa pengamplasan antara mantel Anda harus mengajukan permohonan kembali setelah titik ini, tetapi sebelum waktu pengeringan selesai.

Waktu pengeringan: Pada titik ini epoxy akan siap untuk pasir dan telah mencapai sekitar 90% dari kekerasannya sembuh. Epoxy masih mungkin tetap agak fleksibel pada saat ini, tetapi akan menyelesaikan 100% menyembuhkan selama 1-5 hari berikutnya. Jika suhu udara mendapatkan di bawah 60 derajat, kali kering dapat melipatgandakan dari kali ditampilkan
